The main causes of death for manatees are human-related issues, such as habitat destruction and human objects. Their slow ...
Hunting is the largest source of mortality in Amazonian manatees, and there are no management plans except in Colombia.

Manatees do not have incisors; these have been replaced by horny gingival plates. [50] Some individuals may also inadvertently eat invertebrates (such as small aquatic insects and crustaceans) and will eat fish both in captivity and in the wild. [47] [48] Manatees are nonruminants with an enlarged hindgut. Unlike other hindgut fermenters, such ...
