Welcome back, Herders! Today is about Wolf Eels!!!!! Wolf-eels live in shallow water as deep as 740 feet (225 m). They swim by making deep S-shapes with their bodies, like a snake moving across the ground. The slender fish are as gray as a rain cloud, with large heads and dark spots over their backs. Males have thick jaws and a bulging forehead. Combined with their long, snaggly front teeth they look ferocious, but wolf-eels tend to be aggressive only to other wolf-eels. Wolf-eels mate for life and the pair takes special care of its eggs as they develop. Beginning around age seven, the female lays up to 10,000 eggs at a time, then coils around them and uses her body to shape the eggs into a neat sphere roughly the size of a grapefruit.
