Starfish are ready to eat after 15 minutes of cooking. Starfish have very little meat. Usually you have to break off the legs of the starfish and eat only the seeds and gonads in the center of the starfish. So to make starfish, you have to break off the legs of the starfish, then cut the starfish along the slit in the middle of the starfish, remove the starfish seeds, and put the removed starfish seeds into a pot to steam for 15 minutes. Starfish:It is one of the most representative structural physiology of starfish echinoderms. The body is flattened, mostly five-radial symmetrical, and the body disk is not clearly delimited from the carpus. When alive, the mouth faces downward and the mouth faces upward. The wrists are grooved ventrally and the tube feet extend out of the grooves. The bony plates of the endoskeleton are connected by connective tissue, which is elastic and flexible. The body has spines and forked spines that are projections of the skeleton. Membranous vesicles protruding from the bony plates are covered with epithelium lining the body cavity epithelium, whose inner lumen is connected to secondary body cavities called dermal gills, which have the function of respiration and diffusion of metabolites to the outside world. The plumbing system is well developed. In terms of individual development, there are feather-carpal larvae and short-carpal larvae.
