I really do not see what all the fuss is. The first Europeans to see manatees (Manatae? Manatii?) thought they were the mermaids of legend.
But then, they had been at sea with bad food and worse water for months when they reached the rivers where the manatees (manatae? manatii?) swam. They probably should be forgiven for the lowering of what were already pretty low standards.
stay safe.
