It is a kind of snail, belongs to the shallow sea life shellfish, is the sea hare family of marine gastropods collectively, because of its two pairs of antennae on the head protruding like rabbit ears and so named.

Morphological features:

The two pairs of tentacles on the head of the sea hare protrude like rabbit's ears, and the body is smooth or has many protuberances. The antennae are clearly divided into two pairs, the front pair is slightly shorter, specializing in the sense of touch, and the back pair is slightly longer, specializing in the sense of smell.

Sea hares are small, generally only 10 centimeters long, weighing about 130 grams, the body is ovoid, the body can be deformed when moving. The sea hare is not a mammal, there is no fur on the outside of the body. It belongs to the mollusc family gastropods. But with the common gastropods (such as abalone, snails, snails) is different. The sea hare does not have a calcareous shell, but degenerates into a thin and transparent, non-spiral horny shell, which is buried under the dorsal coat membrane, and can not be seen at all from the outside, but on the back of the body is covered by a thin and translucent horny membrane (which is the same as slugs, so it is also known as the sea slugs), and the thin crust of the shell is generally white with a pearly luster.

The sea hare's foot is quite wide, with both sides of the foot lobe developed, and the back side of the foot extending toward the back. Normally, sea hares use their feet to crawl on beaches or underwater, and make short-distance swims with the movement of their feet.

Species:

There are many species of sea hare, the common ones are "black fingerprint sea hare", "blue spotted dorsal anus sea hare", "spotted sea hare".

Living Environment:

The sea hare prefers to live in an environment where the sea water is clear, the water flow is smooth, and the seaweeds are thick, and it feeds on various kinds of seaweeds. It has a very special set of enemy avoidance skills, is to eat what color seaweed will become what color. Such as a kind of red algae eating sea hare body rose red, eat inkhorn algae sea hare body is brownish green. Some sea hare body surface also has a fluffy and dendritic protrusions, thus making the sea hare's body type, body color and pattern and habitat in the environment of the seaweed is very similar, so it avoids a lot of trouble and danger for themselves.

The sea hare is capable of both passive avoidance and active defense. In the sea hare body there are two kinds of glands, one is called purple gland, born in the edge of the outer coat membrane underneath, in case of enemy, can release a lot of purple-red liquid, the surrounding seawater will be dyed purple, to escape from the enemy's line of sight. There is also a poisonous gland in the anterior part of the outer coat membrane, can secrete a slightly acidic milky liquid, the smell is unpleasant, the other side if contacted with this liquid will be poisoned and injured, or even die, so the enemy smells this odor, far away from avoidance, is the chemical weapon of the imperial enemy.
