Echinoderm - Sunflower Sea Star
Morphology
The Sunflower Sea Star's fleshy body requires water to support itself. Their colors range from orange, yellow and red to brown and sometimes purple. Sunflower Sea Stars tend to have 16 to 24 arms with powerful suckers on them, and they display a radial symmetry.
Biology
The sunflower sea star can extend its mouth, for larger prey, the stomach can also extend outside the mouth to digest prey. To escape predators they can shed arms, which will grow back within a few days in a process called regeneration.
