INTERESTING FACTS: STARFISH
Stars are found not only in the universe and among people, but also in the underwater world. Starfish or sea stars are adapted only to salt water. There are more than 2000 different species.
Starfish are marine invertebrates that belong to the phylum Echinodermata, i.e. they have a pentameric radial symmetry (five arms). Also there are starfish that have three, four or six arms and not all of them are star-shaped. Starfish can regenerate lost arms.
Starfish have an unusual anatomy – they have no gills, scales or fins like fish do, as well as they do not have brain and blood. They use sea water, instead of blood, to pump nutrients through their bodies and are able to digest food outside the body. This is particularly surprising that although starfish have no brain, blood and even the central nervous system, they have eyespots at the ends of the arms. Although these eyespots cannot see details, they are able to differentiate the shades of light, which makes it possible to move through the landscape, to hunt and hide from predators.
Starfish have hundreds of tiny feet at the end of each arm. In order to move, these feet are filled with sea water and make arms to move like feet. This makes it possible for some adult stars to travel at an impressive speed of one meter per minute.
During your dives in Bali and in the vicinity of the island you can meet a large number of starfish that are varied in colors, shapes and sizes.
