Interesting Facts About Starfish and PicturesStarfish do not rely on a jointed, movable skeleton for support and movement (although starfish are still protected by their skeleton), but instead possess a hydraulic water vascular system that aids the starfish in movement.
The water vascular system of the starfish has many projections called tube feet on the ventral face of the starfish's arms which function in movement and aid with feeding.
Starfish can change their gender when it is convenient to them.
The female starfish is capable is releasing over 2 million eggs at any one time, although the average amount of eggs that the female starfish releases is closer to 1 million.
The eggs released by the female starfish are then fertilized by the male starfish and the fertilized eggs develop into larvae which are able to swim about.
The starfish is today considered to be a threatened species of animal mainly due to habitat loss and pollution which are drastically reducing the starfish populations.
