Aplysia is called Aplysia because it looks like a rabbit. The most important one is "aplysia", which looks very similar.

Aplysia is sometimes called sea deer, sea unicorn, sea slug, and manatee in Chinese. The names vary depending on the appearance.

Aplysia is a member of the marine invertebrate family. In terms of biological classification, it belongs to the phylum Mollusca; the class Gastropoda; and the subclass Opisthobranchia.

The biggest difference between Aplysia and other gastropods is that its shell is hidden inside the body and may even degenerate into no shell.

Aplysia is a hermaphrodite with cross-fertilization. During the mating season, you can often see several Aplysia stacked side by side to mate. This is one of the special features of this creature.

Aplysia mainly lives on the reefs of the continental shelf. Some feed on coelenterates; some feed on large marine algae. The feeding organ is the tank-track-like radula in their mouth, and the radula is also the basis for the classification and identification of this creature.

The life cycle of Aplysia lasts from a few days to one or two years. After mating, the adults will lay a ring-shaped egg belt on the bottom rock or reef. When the embryo matures, it breaks through the egg sac and emerges. Floating in the sea, they feed on marine plant plankton or smaller marine animal plankton. When the sensory organs of the larvae initially mature, once they sense the ocean chemicals that induce their sedimentation metamorphosis, the larvae will settle on the attachment and begin metamorphosis. After the metamorphosis is completed, they will become sub-adult sea hares, and then adults. Big sea hare.
