MATERIALS AND METHODS The present study was performed with a total of seven calves of Amazonian manatee under captive Measurements of fin width, tail width and peduncle have been used mostly for periodic monitoring of captive animals, but studies that use these variables as predictors of body weight could not be found. a The Amazonian manatee (Trichechus inunguis) is an aquatic mammal (Family Trichechidae) that inhabits freshwater environments. Some Amazonian manatees living in deep bodies of water apparently fast during dry seasons (November and December) when water levels drop as much as 9 to 15 m (30-50 ft.), eliminating their access to vegetation. It was in Rondônia, however, that the three fossils recently used to describe a new species of manatee, Trichechus hesperamazonicus, were found. It is found living in the freshwater habitats of the Amazon Basin in the countries of Brazil, Peru, Bolivia, Colombia and Ecuador. For this reason is useful have a valid and easy to apply tools (i.e. 99. The largest females may weigh up to 3910 pounds (1,775 kg). R One of the 3 manatee species in the world, Trichechus inunguis is a river dweller that can reach 2.8 m in length and weigh half a ton. At 3 meters (m) long and almost 500 kilograms in weight, the Amazonian manatee (Trichechus inunguis) prefers the calmer waters of the rivers and temporary lagoons found further north and east. They tend to eat much more during the wet season and that allows them to store up fat that they can survive on during that dry season when it is time for a change in the cycle. = £13.99 £ 13. = The Amaz… Mean, standard deviation, maximum and minimum of data collected in the biometry of calves of Amazonian manatee (Trichechus inunguis) in captivity. (2001) [ 26 ] animals up to 3 months of age was analyzed. Manatees are found from the mouth of the Amazon River to the upper reaches of the tributaries of Brazil, Colombia, Ecuador, Guyana and Peru. This is in line with what was found in this study, in which abdominal circumference showed the highest correlation coefficient (0.924) with respect to weight and its regression equation with body weight was the highest coefficient of determination (R2 = 0.855, 70.419 BW The Amazonian Manatee (Trichechus inunguis) is a freshwater species of manatee which inhabits the Amazon basin.Its habitat includes Brazil, Peru, Colombia, Ecuador, Guyana and Venezuela. It is endemic to the Amazon Basin, and occurs from Marajó Island (at the mouth of the Amazon River in Brazil) to the headwaters of the floodplain in Colombia, Peru and Ecuador. The Amazonian Manatee is a common sight around the Amazon Basin. j − Having the tool to predict the body weight of animals using biometric measures could facilitate and improve the management of these animals in captivity, also reducing the effects of stress caused by the manipulation of the animal for weighing. , The species is slow-moving a… The color of this species of manatee can be brownish or gray. ( They are often referred to as the sea cow in this region. = 0.682) (Figure 6), of which the estimation errors were: 2.02, 2.83, 1.86, 4.35, 2.99, and. Amazonian manatees have marching teeth: A unique feature amongst all mammals is that manatees have … 78.072 If fasting is necessary they fat reserves and low metabolic rates allow the Amazonian manatee to survive up to seven months with little or no food.

( (R2 = 0.829, Due to its peculiar shape it has been described as a cross between a seal and a hippo. They continue to be replaced as needed for their entire lives. Table of correlation coefficients of biometric measures with the body weight (N = 58) of calves of Amazonian manatee (Trichechus inunguis) in captivity. Geographical Distribution This is a freshwater species.   The Amazonian manatee species inhabit the Amazon River and the African manatee swims along the west coast and rivers of Africa. The importance of conserving this species is its ecological role as biological control of aquatic plants, contributing to fertilization water and plankton production, and so be a kind of high ecological value [ 3 ]. R Scatterplot of linear regression body weight-fin width (N = 58) of calves of Amazonian manatee (Trichechus inunguis) in captivity. ( It is the smallest of the tree species. They are able to smell using the taste buds on their tongue. Manatees consume about 4% to 9% (15 to 49 kg or 32-108 lb. BW Typically, manatees stay in rivers, seas and oceans along the coast of several countries.   + Meet The Manatees: Introduction . and there weight is 363 to 544 pounds! 2 TW They have also been seen playing games and having fun with each other. R The Amazonian manatee thrives in areas that have abundant vegetation. = 0.187) (Figure 4); Figure 1. 5 Birds Perfectly Adapted to Modern Cities. a We suggest new studies of prediction of BW using biometrics, with animals of similar age to the present study and with more data. They move around often in order to find food, for mating, and to stay safe. Despite eating in a slow and secretive manner, an Amazonian manatee each day is able to eat as much as 8% of its body weight. − This works in their favor as they are able to go for long periods of time without food if they need to. Work done with funding from the 6th Undergraduate Thesis Grant Competition (2016) of La Molina National Agrarian University, Faculty of Animal Husbandry. = 0.615 and R2 = 0.688, What is the size and weight of west Indian manatee? Amazonian manatees are the smallest of the three species. Size: Amazonian Manatees can be up to 2.8 meters long (almost 9 feet), and weigh between 350 and 500 kg (770-1,100 lbs). It was conducted out with 7 calves (4 males and 3 females) of approximately 8 months of age and average body weight of 29.94 ± 0.055 kg… (2), BW With a size of 10-13 feet and weight of 1,100 pounds, the West African Manatee is bigger than the Amazonian Manatee, though of similar size and appearance to the West Indian Manatee except for its blunter snout. − 75.385 ∗ The Amazonian manatee is the smallest member of the manatee family and can be distinguished by its smoother rubbery skin and lack of vestigial nails on its flippers. (2010) [ 27 ] in which the weight ratio was analyzed, overall length and maximum circumference by linear multiple regression and body volume calculated using data from these variables. 0.966 Totally a herbivore, a Manatee may eat up to 10% of its body weight daily, like cows they love to eat, and are thus sometimes called sea cows, a Manatee also is very flatulent, emitting a very vicious overpowering fart. a In conclusion, the biometric measurements of TCL, TL, FW, TW, CIR and PED showed a high correlation with the BW and can be used as predictive variables of BW of manatee calves, as they are easy to be measured. = = BW for its rehabilitation. ) The Columbus monkey and the Spider Monkey weigh a total of 22kg. SENDEFN. ( In addition, we calculated three equations for prediction of body weight, Equation (1) was performed using all biometric measurements (TCL, TL, FW, TW, CIR and PED), in Equation (2) used biometric measurements LT, TW, CIR and PED (R2 > 0.6) and Equation (3) comprises biometric measures TCL and CIR (R2 > 0.8); whose results were as follows: BW If fasting is necessary they fat reserves and low metabolic rates allow the Amazonian manatee to survive up to seven months with little or no food. 3. Your contribution will be appreciated to improve our site. = , TL The Amazonian manatee can reach up to 9 feet in length and weigh up to 500 lbs. Gestation period is 12 months and females give birth to one calf. PED She and Pinto had been tracking Helena since she was released from a manatee rehabilitation center in the Amazon’s Amanã Sustainable Development Reserve on … ( Length at birth is about 90 cm; weight is 10 to 15 kg. which would translate to eating anywhere from 44 to 130 lbs. 2 ∗ Amazonian Manatee. R 004-2014- MINAGRI categorize this species as vulnerable [ 10 ] and are included in Appendix I of CITES (The Convention on International Trade in Endangered Species of Wild Fauna and Flora) [ 11 - 13 ]. R TL 49.929 2 R This is the smallest of the manatee species.   = j The manatee is typically herbivorous, but may occasionally feed on small fish and shellfish. A grown-up manatee can reach up to 3 meters in length and around 450 kg in weight. TCL The manatee has a streamlined body – full around the middle and narrowing to a paddle-shaped tail. 13.025 Amazonian manatee as predictors of body weight, and to generate high reliability prediction equations to facilitate the monitoring and management of the growth of this species under captivity conditions. The average size is just over 9 feet in length and anywhere from 790 to 1,200 pounds. It is known that during the first year of life, most mammalian species gain more length, and only after weaning longitudinal growth increases in proportion to the weight and the regression coefficient tends to approach 3 [ 26 ]. Small amounts of plants will be introduced at a young age and steadily increased with time. 63.198 The heaviest recorded was 836.5 lb (379.5 kg). These rates are similar to those reached by the T. manutus calf at Miami Seaquarium while nursing from its mother Fig. Copyright © 2006-2017 Scientific Research Publishing Inc. All rights reserved. − 70.912 This can result in disease risk for them. The Amazonian manatee species inhabit the Amazon River and the African manatee swims along the west coast and rivers of Africa. The results showed a significant correlation (P < 0.05) between BW and TCL, TL, FW, TW, CIR and PED. The skin is thick and wrinkled. In the case of the Amazonian manatee, the weight/length ratio was calculated only for calves up to three months of age [26, 27].   The research work on this species is scarce because there are no tools that facilitate its management and conservation. They are herbivores and have access to a wide variety of types of plants. Figure 5. (R2 = 0.663, Metabolic rates of Amazonian manatees are among the lowest of any mammal species, being about 36 per-cent of the "normal" eutherian metabolic rate (Gallivan and Best 1980): SMR = 30mb068 where: SMR = stan-dard metabolic rate of T. inunguis (kcal/d) and mb= body weight (kg). = They can consume from 8 % to 10% of their body weight per day. ( PED (2.8 metres). The objective of the present study was to evaluate the sensitivity of the biometric measurements of the Amazonian manatee as predictors of body weight, and to generate high reliability prediction equations to facilitate the monitoring and management of the growth of this species under captivity conditions. ( They tend to live in water that is very murky from the mud so that can make it hard to see them. 3. Biometry and weighing were performed periodically, with the following measurements: body weight (BW), total curved length (TCL), total length (TL), circumference (CIR), fin width (FW), tail width (TW) and peduncle (PED). a BW 29.857 2 (2010) [ 30 ], who concluded that the total curved length is an important measure to describe the growth of manatees. Amazonian manatees are smaller, reaching a length of 2.8 metres (9.2 feet) and a weight of 480 kg (1,056 pounds), and, unlike the other two species, they are darker gray in colour, commonly have a white patch on the chest, and lack nails on the flippers. Total length has been widely used in predicting body mass, body volume and growth curve in Amazonian manatees. As a solitary animal it roams throughout the Amazon basin and can be spotted in Ecuador, Colombia, Peru, Bolivia, Venezuela, Guyana, and Brazil.   Thanks to their low metabolism, manatees have to eat pounds and pounds of plants each day – enough to equal 10 to 15% of their body weight. This species grows to a length of 60 cm SL (for a female specimen) and a maximum weight of 4.6 kg. A herbivorous species, it feeds on a large variety of aquatic and semi-aquatic vegetation such as grasses, water lettuce and water hyacinths. Students and teachers are allowed to use this information for school projects and homework. − CIR a west Indian manatee is 10f.t. It was conducted out with 7 calves (4 males and 3 females) of approximately 8 months of age and average body weight of 29.94 ± 0.055 kg, arranged in pools of sufficient size. The Amazonian manatee makes seasonal movements following the flood regime of the Amazon Basin. 034-2004-AG) [ 15 ]. This difference could be due to the fact that in the present work the data were analyzed in the scale of Kg/m, whereas in the previous works worked on scales of Kg/cm. Reproduction. j (2010) [ 27 ] used 91 data of manatees of different age ranges and total length (73.5 - 261 cm) and body weight (7.8 - 363 kg), in comparison with the present work that we analyzed 58 data of manatees of similar ages and weights, with ranges of total length (1.10 - 1.18 m) and body weight (23.7 - 44 kg), leading to a more homogeneous group of animals; and in the study by Rosas et al. The Amazonian manatee (Trichechus inunguis) is a species of manatee of the order Sirenia. The largest recorded Amazonian manatee was 9.2 feet (2.8 meters). Fasting the manatees for 2 wk caused a 17.5% decrease in body weight and a 22.5% decrease in metabolic rate but no decrease in the weight-specific metabolic rate. Mating can occur any time of the year, and tends to do so as long as there is enough food and low stress. (3). There are mating herds that form with a male and several females.   Abdominal circumference has been little used in manatees; however, there are studies such as Amaral et al. Figure 4. 2.804 The longest recorded specimen measured 9.2 feet. = 0.965; 0.91). The watergulp, Fluvisaurus hauristus, is an aquatic, viviparous, manatee-like thescelosaur from the Amazon River, in The New Dinosaurs: An Alternative Evolution. Seasonal Variations in Blood Parameters of the Amazonian Manatee, Trichechus inunguis Elton P. Colares *, Ioni G. Colares, ... Every season the body weight of each manatee was determined with a Salter balance (500 x 0.5 kg). R West African manatees closely resemble West Indian manatees and are similar in size. j Posted by BioExpedition | Oct 30, 2012 | Mammals, Manatee |. ∗ Best Seller in Girls' Jackets +7 Trespass. ) On an average day an Amazonian manatee can feed on up to 5 to 18% of its body weight. = However, the regression coefficient obtained in the present study was higher (b = 80.1) than previously reported. Observations during the fast indicate that manatees reduce their daily energy require-ments by a reduction in activity. The maximum length and mass measured were 266.5 cm and 379.5 kg, respectively. (R2 = 0.855, = 2. Manatees are believed to have evolved from a wading, plant-eating animal. A signal would tell them that Helena, an Amazonian manatee, was still alive. ) 2 j ) The objective of the study was to determine a prediction equation of body weight of Amazonian manatee calves in captivity using their biometry. It is found in flooded forests and meadows when food is abundant, but water levels fall from July-August and some become restricted to deep lakes until the … This low metabolic rate may be essential for survival CIR As is the case with others manatee species, the females are a bit larger than the males. This species of manatee is basically a fresh water creature found in the upper reaches of the Amazon river and its tributaries that span the countries of Brazil, Guyana, Colombia, Ecuador and Peru. According to National Geographic, a manatee can eat a tenth of its own weight in 24 … It is unknown in the wild. 04 ($21.04/Count) $24.95 $24.95 which are necessary in monitoring captive or semi-captive animals for the purpose of having an animal status indicator and improve the conditions (nutritional, environmental, structural, ethological, etc.) 95.313 Amazonian Manatee (Trichechus inunguis), Biometric Measurements, Body Weight, Weight Prediction, Correlation. 2 R 2 14.801 One particularly large specimen weighed 480 kilograms (105 pounds).   Rainforest animal weights 1. ∗ The Giant River Otter and the Mandrill weigh a total of 56kg. It can hold its breath underwater for up to 20 minutes! The Amazonian manatee is completely aquatic and never leaves the water. They instinctively close the nostrils when they are under the water. ... Amazonian manatee (Trichechus inunguis), Amazon river dolphin (Inia geoffrensis), bush dog (Speothos venaticus), short-eared dog (Atelocynus microtis), harpy eagle (Harpia harpyja) and the Arapaima fish. Captive adults daily consume from 9 – 15 kilograms (20 – 33 pounds) of leafy vegetables. They are often referred to as the sea cow in this region. The females are free to leave that herd and may mate with more than one male. j At the same time blood samples were collected. TCL ∗ 56.841 = 89.172 For example, they may go very close to humans to rub against them due to their ongoing need for touch.

Using their divided upper lip, an adult manatee will commonly eat up to 10–15% of their body weight, or 50 kilograms (110 lb), per day, which requires the manatee to graze for several hours per day. − Conservation Status: All three species are rated Vulnerable; Other interesting manatee facts: Manatees have the smallest brains in relation to body mass of all mammals. Jaguar: Amazon Rainforest Animals-Jaguar. ) Can you solve the puzzles to find the weight of each animal? Amazonian Manatee Diet. The 3 Toed Sloth and the Spider Monkey weigh a total of 13kg. Scatterplot of linear regression body weight-peduncle (N = 58) of calves of Amazonian manatee (Trichechus inunguis) in captivity. PED 2.556 ∗ = 0.852) (Figure 3); It is about 1 year later when a young calf is born. 2 The young are very well cared for by their mothers, and will nurse up to 18 months. Amazonian manatees are shorter and more slender than the Indian manatees. The equation for body weight/length relationship was M = 0.00001070 * TL 3.122 ( r2 = 0.984) (Equation I) and no differences between sexes and between captive and free-ranging animals were found ( P > 0.05). , They also tend to get too close to boats or fishing nets out of curiosity. a The 3 Toed Sloth and the Columbus Monkey weigh a total of 17kg . Names: The Amazonian manatee is also referred to as a sea cow, South American manatee, and peixe-boi (in Brazil). Amazonian manatees breed throughout the year. The African manatee and the West Indian manatee are more closely related to each other than to the Amazonian manatee. They have also been seen playing games and having fun with each other. They are one of three species still existing in the genus Trichechus, the only genus in the family Trichechidae. ( Amazonian manatees are found in waters of the Amazon River and its tributaries in Brazil, Guyana, Colombia, Peru, and Ecuador. Amazonian manatees are smaller, reaching a length of 2.8 metres (9.2 feet) and a weight of 480 kg (1,056 pounds), and, unlike the other two species, they are darker gray in colour, commonly have a white patch on the chest, and lack nails on the flippers. = 0.657) (Figure 2); Ranges of body weight and size observed are 7.5–346.5 kg and 76.0 –255.5 cm for captive males, 8.1–379.5 kg and 71.0–266.5 cm for captive females, and 120.0–270.0 kg and 162.0 –230.0 cm for free-ranging manatees, respectively. In addition, three linear multiple regression equations of BW were calculated using the predictor variables previously analyzed by Person correlation analysis. All the young manatees appear to be in good health and demonstrate an average weekly weight increase of 1 kg and growth rate of 1 . Manatees are born underwater. Manatees are typically found in shallow coastal areas and rivers where they feed on sea grass, mangrove leaves, and algae. As a result, it is also very difficult to get a definite number about how many of them remain in the wild. 2 The elusive Amazonian manatee (Trichechus inunguis) is a large plant-eating mammal that lives in freshwater. While with the pups the cub had developed play behaviour patterns which closely resembled those seen among hand-reared orphaned … Amazonian manatee** Antillean manatee (West Indian Manatee) West Indian manatee (no subspecies)** Antillean manatee (West Indian Manatee) Trichechus manatus manatus: LINNAEUS, 1758: Photo by: E.

ERRORS in the site, please contact us. They tend to live in bodies of water that have connections to larger rivers so that they can always find enough vegetation.

They are often referred to as the sea cow in this region. Although an Amazonian manatee has very small eyes, surprisingly it can see very well, and it even has a membrane that it is able to draw across its eyeballs for protection. ∗ The females are much younger, with the average age being around 3 years old. predictor equations, weight/length ratios, body condition index, etc.) These herbivores munch on food for almost half the day, eating ten percent of their body weight in plant mass every day. One particularly large specimen weighed 480 kilograms (105 pounds). a = 0.852), this allowed to calculate the Equation (3), summarized in the use of the variables girth and total length. for an average adult manatee) of their body weight in wet vegetation daily. The only fresh water manatee in the world, the Amazonian manatee is found in the waters surrounding Iquitos Peru and throughout the Amazon basin. 0.237 Don’t even try to compete with the manatee! Amazonian manatees are smaller, reaching a length of 2.8 metres (9.2 feet) and a weight of 480 kg (1,056 pounds), and, unlike the other two species, they are more blackish in colour, commonly have a white patch on the chest, and lack nails on the flippers. Males are from 5 to 6 years of age when they mate. Nonlinear growth models for this species have been studied using body length information from captive animals. As this food is low quality, a manatee must spend a lot of time eating and it can consume up to 15% of its body weight every day. 10 Facts About Amazonian Manatees: 1. to 14 f.t. a ) FW Natural Science Furthermore, the use of other biometrics such as curvilinear length and circumference of the body are also important tools in the estimation of body weight in predictive models, such as the seals [ 23 - 25 ]. − Length at birth is about 90 cm; weight is 10 to 15 kg. The Sirenia order is the only order of aquatic mammal’s survivors that are exclusively herbivorous [ 4 ]. This species of manatee seems to have a slower metabolism than the others. ) j The new teeth will come in at the back and then move the others forward. A manatee can eat a tenth of its weight in just 24 hrs. The biggest of every single marine well evolved mammal found in the Amazon River and its streams. Figure 3. For comparison, do you think you eat a tenth of your body weight in 24 hours?
