Each sea hare is both male and female and has both sexual organs. Sea hares may lay up to eighty million eggs apiece but most of these are eaten by predators.
Many kinds of plants, birds, fish, shellfish and other animals depend on the special mix of fresh and salt water found in sloughs and estuaries. When we protect wetlands against development, we protect the homes of many animals.
When threatened by predators, sea hares release a dark purple fluid in defense. The ink gets its purple color from a pigment in the red algae that makes up part of the sea hare's diet.
Sea hares can't see like we do; their simple eyes can only tell light from dark.
