the The Star Fish/Sea Star
The sea-star/starfish is one organism in the coral reef that can regenerate. It belongs to a group of marine animals called echinoderms. Its scientific name is Asteroidea. In science class we learned about regeneration. Regeneration means to recover or to regrow limbs. The sea-star can regenerate entire limbs. The reason why it is called a sea-star is because it looks like a star in the sea. The sea-star doesn’t contain blood. You can find this organism on rocks, near some docks, tide pools, lagoons, seagrass beds, and on rugged coastlines. The sea star is an invertebrate, meaning it has no backbone. They can be found around the world in the Indian and Pacific oceans. All sea stars cannot survive in fresh water. It would die trying to live in freshwater. It eats sea cucumbers, barnacles, snails, sea urchins, clams, and mussels. The natural predators of a sea-star are sharks, manta rays, alaskan king crabs, and other sea-stars. Without sea-stars the whole ecosystem would collapse. The reason for this is because other species such as sea cucumbers and barnacles would over populate. Decomposers of the coral reef can be sea cucumbers, snails, crabs, fan worms, bristle worms, and bacteria. They help break down the nutrients in the coral reef.
Why Is Regeneration So Important To The Sea Star?
It is important because without it the sea star wouldn't be able to survive. Regeneration isn't just used to recover limbs. It's also used to reproduce asexually. The sea star can reproduce sexually by sending millions of eggs and sperm into the sea and mixing together. It reproduces asexually by ripping off a piece of itself and regenerate from that limb. That'll make two sea stars with the same DNA.
