Anatomy of the Starfish Facts

A lot of starfish facts talk about the anatomy of this sea creature. The shape of the common starfish which is what people perceive as a star is already interesting as it is. But if you look into the structure both internal and external parts of the starfish, you will really be fascinated by this animal.

Just like humans, the starfish has different skin layers such as the epidermis and the dermis. But they also have an epithelium layer where the muscles can be found. One of the most interesting aspects of the anatomy of a starfish is the vascular system. Starfishes are not mammals so they do not have blood. Instead, the vascular system makes use of seawater to aid in its movement, gas intake, adhesion, and the handling of food. The body of the starfish is filled with canals where water flows in and out of the system.

But even without actual red blood, the starfish still has a circulatory system with a heart that constantly beats at a rate of 6 times in one minute. The movement of the fluid in this system aids in spreading nutrients in the body but has no connection with respiration unlike humans.
