With different characteristics and habits.
1, the difference in biological classification: the sea hare belongs to the gastropods nudibranchs, while the squid belongs to the cephalopods decapods.
2, morphological characteristics of the difference: the sea hare's body is relatively more rounded, ovoid or oval, with two pairs of antennae on the head, like a rabbit's ears protruding, the body is smooth or have a lot of protrusions. The squid has a more elongated, conical or cylindrical body, with 10 tentacles in front of the head and a triangular fleshy fin at the end of the tail.
3, the difference in food: sea hare mainly ingest plant matter, such as seaweed, seaweed, etc., the digestive system is relatively simple. Squid is a carnivore, mainly prey on other small fish, crustaceans, etc., the digestive system is more complex.
4, the difference in the way of movement: sea hares usually move their bodies through muscle contraction. The squid swims quickly by spraying water, and the water spray holes can spray water to push the body forward.
5, the difference in reproduction: sea hares usually reproduce through in vitro fertilization, hermaphrodites, can mate with each other. Squid usually reproduce through in vivo fertilization, where the male injects semen into the female and the fertilized eggs develop into larvae in the female before being released.
6, the difference in eating experience: sea hare's meat is usually more delicate than squid, the taste is more crisp, fishy flavor is relatively small. Squid, because of its larger size and greater toughness, is usually used to make dishes such as barbecue and stew. In summary, sea hares and squids are significantly different in terms of their biological classification, morphological features, feeding habits, locomotion, reproduction and eating experience
