Question

know as sea cows,they are large fully aquatic and herbivorous mammals they will soon become extinct if they are continuously hit by boats and cut by propellers​

Answer 1

Answer:

Manatees look a bit like walruses or chunky porpoises and are sometimes referred to as sea cows, but they're actually much more closely related to elephants.

Explanation:

Manatees are aquatic mammals with voracious appetites—spending up to 8 hours a day grazing. Size relative to a 6-ft man: Manatees are sometimes called sea cows, and their languid pace lends merit to the comparison.
