The starfish is a marine invertebrate that can be found in both salt and fresh water. There are over 1,500 different species of starfish, ranging in size from a few inches to over a foot in diameter. Starfish are typically a reddish-brown color, but can also be found in shades of orange, yellow, and even blue.
Starfish are echinoderms, which means they have a skeleton on the inside of their body. This skeleton is made of calcium carbonate, which is the same material that seashells are made of. Starfish use their skeleton to help them move and to protect their internal organs.
One of the most unique things about starfish is their ability to regenerate lost body parts. If a starfish loses an arm, it will grow back a new one. If a starfish loses its head, it will die, but the rest of its body will still regenerate a new head.
Starfish are carnivores and feed on small crustaceans and fish. They use their five arms to capture prey. Starfish can also digest food outside their bodies, which allows them to eat prey that is larger than they are.
Starfish are not very good swimmers and typically move by crawling along the ocean floor. They can also use their arms to swim short distances.
Starfish are typically found in coral reefs and other areas with rocky surfaces. They can survive in both salt and fresh water, but they cannot live in water that is too cold or too hot.
Starfish are a popular pet for marine aquariums. They are easy to care for and can live for many years.

Do sea stars have eyes?
Do sea stars have eyes?
Sea stars, also known as starfish, are marine invertebrates that belong to the class Asteroidea in the phylum Echinodermata. They are found in all of the world’s oceans and can be distinguished from other echinoderms by their radial symmetry.
Sea stars have a number of adaptations that allow them to thrive in the marine environment. One of these adaptations is their ability to see. Sea stars have two types of eyes, primary and secondary. The primary eyes are located on the tips of the arms and are used to detect movement and light. The secondary eyes are located on the underside of the body and are used to detect shapes and colors.
Sea stars use their eyes to find food, avoid predators, and find their way back to their homes. They are able to see in both light and dark environments and can even see in the deep ocean where there is little light.
Sea stars are not the only marine invertebrates that have eyes. Other animals that have eyes include octopuses, squids, and cuttlefish.
