The other really important part to the sunflower star is its tube feet. All the main organs play there part and are held by the oral disk making it a vital part of the sunflower starfish.

There is a ring shaped water canal in the main organs, which has branches leading out to the legs and tub feet.

The oral disk is a disk in the center of the sunflower starfish which contains its main organs. When they grow up they can have about sixteen to twenty four legs. They do have a big difference in legs to normal starfish’s, when they are young they have a normal amount of legs though, which is five. The arms of a sunflower star fish are another very interesting part of them. The skin on the sunflower star fish is complicated but suits its life style. From respiration the sunflower has to store and release wastes which is where the gills come in, but also are used for absorbing oxygen. The gills of the sunflower starfish are located in places called papules, which are tine raised areas where it is thinner. The sunflower starfish’s ossicles are more widely spread than other starfish, which is why the sunflower starfish is more flexible and soft. All sunflowers have ossicles, which are the hard skeleton units under the skin. These are tiny stalked pincers that cover all the skin. The covering or protection is called Pedicellariae. The sunflower starfish has soft flexible skin, that is nevertheless very protective for defense from predators and parasites. View of the Sunflower starfish tube feet.
