|Description: Sea hares are categorized as mollusks and some have small internal shells to protect vital organs. They have two tenacles atop their heads that resemble a hare's ears. Sea hares live in a variety of intertidal habitats, from grassy to rocky areas. They are herbivores that consume algae, seaweed and other plant life. They move very slowly by flapping their "wings", making them an easy prey for predators. Their main defense mechanism is emitting a dark inky substance in the water which in some cases is toxic.
