Seacow is known locally as dugong, a unique animal, being the only herbivorous mammal in existence today. We probably owe our childhood fantasies of the mythical mermaid to the dugong, which, because of its fish-like tail, smooth brownish skin, mammary glands, and woman-like genitalia, was often mistaken by sailors, weary from long voyages, as a mermaid. The dugong can grow to more than three meters in length and can weigh more than 400 kg. Its body is torpedo-shaped with small short flippers and whale-like flukes. Its lip is shaped like a disk with thick hair.
