Structure of Body

Starfish is not really fish because fish is composed of backbones, fins and gills. Starfish is an echinoderm, which is an invertebrate that has a proportional radial body. Instead of scales, starfish species are mostly equipped with a leathery, rigid skin, which protects them against the attack of predators like birds and fishes. Calcium carbonate makes up the skin of all starfishes.

Most of the starfish species are equipped with five arms, which extend out of a central point; nonetheless, there are a number of exceptions. Let us say for instance, the Coscinasterias calamaria and Sunflower stars can have up to eleven arms and twenty-four arms respectively. Eyespots are contained in the arms of starfish that are sensitive to light and responsible for detecting motion.

One of the most interesting starfish facts is that they have the ability to regenerate any injured or lost arms throughout a particular period of time. National Geographic reports that there are a number of species whose arms are home to their vital organs. For that reason, limbs that have been separated from the body can be capable of regenerating on their own and eventually become new starfish over time.
