Squid lives in the sea not too far from the shore. Every spring, when spawning, groups of squid swim to the shore to lay eggs. The egg is wrapped in a rod-shaped transparent colloid sheath. There are often many rod-shaped egg sheaths attached to rocks or other objects at the bottom.

The incubation period varies from species to species. For example, the cuttlefish Sepiella maindroni takes about 65,438+0 months, while the squid from China only takes about 8 ~ 65,438+06 days. The water temperature has a great influence on the incubation time, and the incubation rate is very high, generally reaching 70~80%.

The hatched larvae are similar in appearance to their parents, and can swim back and forth in the water layer with the help of funnel spray to grab food. Larvae grows very fast, and it can grow to be close to the trunk length of its parent in about half a year. In the second year, the gonads are fully mature and return to the sea where they were born to mate and lay eggs.
