Manatee conservation. Manatees are large marine mammals that inhabit slow rivers, canals, saltwater bays, estuaries, and coastal areas. They are a migratory species, inhabiting the Florida waters during the winter and moving as far north as Virginia and into the Chesapeake Bay, sometimes seen as far north as Baltimore, Maryland and as far west ...
Manatee counts are highly variable without an accurate way to estimate numbers. In Florida in 1996, a winter survey found 2,639 manatees; in 1997, a January survey found 2,229, and a February survey found 1,706. [18] A statewide synoptic survey in January 2010 found 5,067 manatees living in Florida, the highest number recorded to that time. [41]
The average West Indian manatee is about 2.7–3.5 m (8.9–11.5 ft) long and weighs 200–600 kg (440–1,320 lb), with females generally larger than males. [15] The largest individual on record weighed 1,655 kg (3,649 lb) and measured 4.6 m (15 ft) long.
In 1996 ,manatees were placed under protection through Fishery Decree Law 164. This law provided penalties against those who manipulate, harm, or injure manatees. The hunting of manatees in Cuba in the 1990s may have been the result of economic hardship, with the manatees being seen as a source of protein. [ 71 ]
In 2021 and 2022, Florida’s manatee population took a hit as thousands of manatees died of starvation. ... Seventy-two manatee deaths so far in 2023 were linked to watercraft.

Sirenia is the order of placental mammals which comprises modern "sea cows" (manatees and the Dugong) and their extinct relatives. They are the only extant herbivorous marine mammals and the only group of herbivorous mammals to have become completely aquatic. Sirenians are thought to have a 50-million-year-old fossil record (early Eocene -recent).
Manatees are omnivores; and are known to occasionally eat clams, mollusks, and fish found in nets. [7] The percentage of the diet that is composed of non-plant material varies based on location, [ 1 ] with manatees living off the coast having a lifetime average of 50% non-plant material. [ 1 ]
