 The ocean urchin is found over the sea depths around the world, however seldom in the colder, polar locales. Ocean urchins are normally found along the rough sea depths in both shallow and more profound water and ocean urchins are additionally ordinarily discovered possessing coral reefs. There are about 200 distinct types of perceived ocean urchin, that come in all shapes and sizes. Some ocean urchins are shrouded in long thin spikes where others have a hard shell that is comprised of pasty plates. The red ocean urchin is the longest living animal on earth, with some living over 200 years.

 Ocean urchins are omnivorous creatures and in this way eat both plant and creature matter. The ocean urchin principally nourishes on green growth on the coral and rocks, alongside breaking down issue, for example, dead fish, mussels, wipes and barnacles. Ocean urchins are preyed about by numerous predators that possess their marine condition, yet in addition those creatures that don't. The fundamental predators of the ocean urchin are crabs, extensive fish, ocean otters, eels, winged creatures and people. In a few nations, certain types of the ocean urchin are chased and filled in as a delicacy.

 Ocean urchins have a round formed body and with long spines that chill out. The spines of the ocean urchin are utilized for insurance, to move about, and to trap sustenance particles that are gliding around in the water. Ocean urchins have five combined lines of little tube feet which are found among the spines. The feet of the ocean urchin have suckers which help the ocean urchin to move about, catch nourishment, and to clutch the sea floor. Ocean urchins additionally have little paw like structure among their spines which the ocean urchin utilizes for assurance. These structures (known as pedicellarines) are little stinging structures that are utilized for barrier and acquiring nourishment, as well as indispensable in keeping the body of the ocean urchin clean.

Ocean urchins produce amid the spring, and the female ocean urchin discharges a huge number of minor, jam covered eggs into the water that are then treated by the sperm of the male ocean urchin. The minor ocean urchin eggs turn out to be a piece of the microscopic fish and the ocean urchin babies (hatchlings) don't incubate for a while. The ocean urchin youthful won't turn out to be sufficiently expansive to withdraw from the microscopic fish and down to the sea floor until the point that they are somewhere in the range of 2 and 5 years of age. Because of digging on the sea floor and contamination in the water, the ocean urchin populaces are declining and the ocean urchin and today thought to be undermined with termination.
