How much does a West Indian manatee weight?

It is hard to guess what a West Indian manatee weights. But we have the answer:

An adult West Indian manatee (Trichechus manatus) on average weights 467.16 kg (1029.91 lbs).

The West Indian manatee is from the family Trichechidae (genus: Trichechus). It is usually born with about 29.62 kg (65.3 lbs). They can live for up to 30 years. When reaching adult age, they grow up to 3.5 meter (11′ 6″). Usually, West Indian manatees have 1 babies per litter.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The West Indian Manatee (Trichechus manatus) or “sea cow”, also known as North American manatee, is the largest surviving member of the aquatic mammal order Sirenia (which also includes the dugong and the extinct Steller’s sea cow). It is further divided into two subspecies, the Florida manatee (T. m. latirostris) and the Antillean or Caribbean manatee (T. m. manatus), based on genetic and morphological studies. The Florida subspecies is primarily found along the coasts of Florida, but its range extends as far west as Texas and as far north as Massachusetts. The Antillean subspecies has a sparse distribution throughout the Caribbean, ranging as far north as Mexico and as far south as Brazil.Manatees are obligate herbivores, have developed vocal communication abilities, and are covered in highly sensitive vibrissae that are used for feeding and navigation. In breeding season, several males form mating herds around an individual female; on average, one calf is born to a female manatee every two to three years.The West Indian manatee was listed as endangered under the Endangered Species Act in the 1970’s, when there were only several hundred left, and the decades since have witnessed significant efforts by federal, state, private, and nonprofit organizations to protect these species from natural and human-induced threats, particularly collisions with watercraft. On March 30, 2017, the US Secretary of the Interior Ryan Zinke announced the federal reclassification of the West Indian manatee from endangered to threatened, citing a substantial increase in the total population.
