sea cow

Definition

The term "sea cow" refers to a large sea animal that eats sea grass and other vegetation on the ocean floor.

This animal is grey with thick skin. It moves in the water using its flippers.
The skins or hides of the sea cow were used by people in Bible times for making tents. These animal hides were used in the coverings for the tabernacle.
It was nicknamed the "sea cow" because it eats grass like a cow does, but they are not similar in other ways.
Related animals are the "dugong" and the "manatee."
