The front end of the touch wrist has a sucker, and there is a horny tooth ring in the sucker. When catching food, use the touch wrist to entangle and swallow it. They like to flock together, especially during mating and spawning periods in spring and summer.

The first pair is in the middle of the back, and 2~5 pairs are arranged in turn to the ventral side. The fourth pair of wrists is especially long. The end is expanded into tongue shape. The front end of the body is spherical. The top is the mouth. There are 10 wrists in total. There are 8 short wrists. There are also two long touch wrists for predation. There are oral membranes around them. They are called touch wrists. They can prey and can be retracted into the touch wrist sac.

Difference in feeding habits between squid and cuttlefish

1. Squid: Squid is a fierce carnivorous animal. Its food is mostly small pelagic species such as small male fish, sardines, scad and shrimp. It also preys on a large number of its own kind. It is also an important prey for tuna, mackerel, hairtail and seabirds.

When attacked by enemies, it will eject a stream of ink from the ink sac, dye the surrounding seawater black, and then take the opportunity to escape.

The difference between squid and squid

1. Squid: Squid is distributed in tropical and temperate waters between 40° N and S. The world's main squid fishing grounds are in the northern South China Sea, Siam Bay, Kyushu, central Philippine Islands, western Western Europe and eastern and western waters of the United States. Fishing grounds are mostly located around islands and reefs, where the water flow is gentle, salinity is high, the bottom is coarse and hard, the seabed is concave, and the coastal water system and warm water system meet.

2, squid: squid distributed in the world's oceans, mainly living in tropical and temperate coastal shallow water, winter often moved to deeper waters. Common squid reproduce in spring and summer, laying about 100 to 300 eggs. There are many kinds of squid in China, and Sepiella mansoni abounds in the East China Sea. Loligo formosanus distributes in the south of Taiwan Strait, Shantou offshore and Beibu Gulf as spawning sites.
