Just the information of a sea creature! Thanks

Sea money, also called sand money sea urchin. The body is flat and disc-shaped, especially suitable for burrowing into the sand, and the body is covered with fine spines for digging and crawling. The mouth is located below the body**.

The upper surface of the body is 5 radially symmetrical, like 5 petals from the center. Most of the coins are 510 centimeters (24 inches) in diameter.

This is a sea urchin shell, which is the skeleton of a sea urchin.

Sea urchins are a class under the phylum Echinoderms and are a class of invertebrates that live in the shallow waters of the ocean. The main feature is that the body is spherical, disc-shaped, or heart-shaped, and there is no wrist. The endoskeletons heal each other to form a solid shell.

The mouth of the sea urchin is under the body, and there are 5 pairs of branched gills around the mouth, which are the respiratory organs. Most species have complex chewers in their mouths with teeth that allow them to chew food. The digestive tract is long tubular and coiled in the body.

Most of them feed on algae, but there are also carnivorous species that feed on hydras and worms.

When a sea urchin dies, the soft tissues of its body disappear, leaving only a hard, spherical (disc-shaped) skeleton. Sea urchin shells.

Judging by your **, this one is a stingray. Stingray is a tropical seawater water, it is a cartilaginous fish, and there are now many varieties of stingray that we keep as aquarium fish. Stingrays generally have a flattened, slightly round or diamond-shaped body, cartilage without scales, and well-developed pectoral fins, like butterflies spreading their wings, and their tail is whip-shaped, with venomous spines.

Stingrays live on the bottom of the sea. Stingrays tend to feed on benthic small invertebrates or filter-feed zooplankton.

I've seen this in the Sea Life Museum, and it seems to be called a water ghost.

It's an alien creature, you've got a treasure!
