Trichechus manatus (American Manatee) is a species of mammals in the family manatees. They are listed as vulnerable by IUCN and in cites appendix i. They are associated with freshwater habitat. They are native to Antarctica, The Neotropics, Atlantic Ocean, and The Nearctic. They are omnivores. Individuals are known to live for 360 months and can grow to 4 m. They rely on lift powered swimming to move around.

URI: http://eol.org/schema/terms/vulnerable
Definition: A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.

URI: http://eol.org/schema/terms/CITES_I
Definition: Appendix I lists species that are the most endangered among CITES-listed animals and plants. They are threatened with extinction and CITES prohibits international trade in specimens of these species except when the purpose of the import is not commercial, for instance for scientific research. In these exceptional cases, trade may take place provided it is authorized by the granting of both an import permit and an export permit (or re-export certificate). Article VII of the Convention provides for a number of exemptions to this general prohibition.

URI: https://eol.org/schema/terms/lift_based_swimming
Definition: Hydrofoils, or fins, are used to push against the water to create a normal force to provide thrust, propelling the animal through water. The reduction of fin cross-sectional area helps to minimize drag, and therefore increase efficiency. Regardless of size of the animal, at any particular speed, maximum possible lift is proportional to (wing area) x (speed)<sup>2</sup>. Dolphins and whales have large, horizontal caudal hydrofoils, while many fish and sharks have vertical caudal hydrofoils.
