West Indian Manatee: Species Profile
While some claim the West Indian manatee is ugly, with ‘a face only a mother could love,’ most people seem drawn to this marine creature, describing it as homely and having the appeal of a plump grandmother with flippers like oven mitts, outstretched as if inviting a hug.
Manatees may not win the gold in a beauty contest, but they definitely take the prize for popularity. A trendy target of the tourism industry, manatees put up with an annual intrusion of humans who leap into their winter freshwater havens to commune with the placid sea cows. Whether it’s their sad, puppy-like demeanor or their sluggish, gentle manner, something about manatees is awfully endearing.
Primarily herbivorous, manatees spend up to eight hours each day quietly grazing on seagrasses and other aquatic plants, though they will occasionally feed on fish. Manatees surface for air about once every five minutes, but can remain submerged for up to twenty minutes when they are resting. Their lungs are positioned along the backbone, which helps with buoyancy control. They swim by waving their wide paddle tails up and down, and because they do not possess the neck vertebra that most other mammals have, they must turn their entire bodies to look around.
Manatees can hear quite well, at least at high frequencies. This is likely an adaptation to shallow water living, where low frequency sounds aren’t transmitted well because of physical barriers. Their inability to hear the low frequency churning of an approaching boat might explain why manatees are susceptible to injury by boat propellers, a top reason for the decline in their populations.
