Will

The scientific name of the sea centipede is sandworm, which taxonomically belongs to the phylum Annelida, class Polychaeta, order Vaginata, family Sandworms. A kind of animal fishing bait. The body is clearly divided into segments, and the two sides of the body segments protrude into warty feet with bristles, which are used for action.

Sea centipedes can bite. Normally the sea centipede will not attack people for no reason, but when the sea centipede feels threatened, such as when its body is pinched, when it is suddenly pawed, or when its tail foot is stepped on, it will bite the object that poses a threat to it. When a person is bitten by a small centipede, redness, swelling and pain usually occur only locally.

Sandworms are mostly dioecious and have no obvious reproductive organs, only in the pre-reproductive period to form the reproductive glands, appearing body color or morphology changes, called iso-sandworm body. Its development is more complex, the fertilized egg must go through the spiral egg cleavage, tandem wheel larvae, after the tandem wheel larvae, wart-footed larvae, just jointed larvae and other development to form an adult body.

Habits

Sandworms like to inhabit the intertidal zone, but of course they can be found in the deep sea. Anglers can find sandworms under rocky outcrops, in crevices in rocks, and in coral thickets. The sandworm's diet consists mainly of other worms and small animals. The reproduction of sandworms is also very peculiar. Sexually mature sandworms will leave their habitat and head to the surface to oviposit their eggs, at which time there will be multiple males swirling around a female, which is known by experts as the Wedding Dance. At the end of the wedding dance, the reproduction of the sandworms also ends, and both male and female sandworms will die one after another and then fall into the sea.

Economic value

Sandworms and brine worms are one of the main components of the food chain of marine organisms, and they are good food for fish, shrimp, and crabs, so they are quite important to the aquaculture industry. Sandworms have medicinal and therapeutic value, has been utilized as food and nutritional health products. Therefore, the demand has increased, in addition to artificial breeding to provide bait and food, the demand for natural resources is also relatively aggravated, in order to maintain the marine ecological balance, the rational use of such resources, some areas have formulated relevant fisheries regulations to strengthen the protection and management.
