The possessive form is the 'starfish's arms'.
Starfish are able to reproduce sexually and asexually. Asexually, the starfish are able to reproduce if part of the starfish's arm is removed, along with part of the central body. From that detached piece, another starfish will form, along with the first starfish regenerating a new arm where the original arm was located.
Flatworms have the ability to regenerate into two new beings if they are split in two. This is due to their unique biological structure and regenerative abilities.
Starfish can either spawn together with eggs and sperm or they can reproduce by themselves. A new starfish can form from a separated part which is considered reproduction. They don't exactly have mating behaviors though.
No, cutting a starfish in half will not result in two separate starfish growing from the pieces. While some species of starfish can regenerate limbs, they do not have the ability to form two separate individuals from a single cut piece.
there are cusion starfish, reef starfish, spiny starfish and fire brick starfish in new zealand.
It is called toilet water.
No. There is no hard, inflexible exoskeleton. The starfish skin has hard protuberances called ossicles, in the form of small plates and spines, which offers most species some protection. The only way a starfish can become smaller is through extreme starvation, disease, or losing one or more arms to a predator. In many starfish, the arms will regrow.
Since starfish are saltwater creatures you should be able to acquire one form your local petstore. If no local petstore or they do not carry a saltwater section, then there is always thousands of online retailers.
