COMMON PURPLE SEA STAR
If the purple sea star looses an arm, a new one will grow in its place. The single arm will often regenerate four new ones and a body. Two new starfish! Wouldn't it be wonderful if we were able to grow back fingers and arms like a sea star?
The bull Kelp is attached to the rocks by a holdfast. A hollow bulb allows leaf like blades to float near the surface to be exposed to the sun for photosynthesis. Look for the whip like stalks that have broken loose and washed ashore after storms.
If you look between the foot and the shell of the keyhole limpet you will probably find a scaleworm. These two animals live together in a symbiotic or 'friend-helping-friend' relationship. The shelled limpet shares its home and food with the scaleworm and in return the scaleworm snaps at the tube feet of attacking purple sea stars.
