@momentsgang: Sea urchins are spiny, globular echinoderms in the class Echinoidea. About 950 species of sea urchin are distributed on the seabeds of every ocean and inhabit every depth zone from the intertidal seashore down to 5,000 meters. The spherical, hard shells of sea urchins are round and covered in spines. Sea urchin is served in a variety of forms across many cultures. In Japanese restaurants it is often served raw, with rice, or tucked into dumplings. It's also popular in Mediterranean cuisine where you will find sea urchin blended into sauces, tossed with pasta, or spread on crostini. #EduTok
