What might happen if a predator bit off one of the arms of the starfish?
Asexual Reproduction An amazing thing can happen when a starfish loses a limb — if it’s not eaten by a predator, that is. In this case, a severed limb can become an entire body, producing an entirely new starfish.
Do starfish impregnate themselves?
Most adult starfish of other species do reproduce via a separate male and female. The extreme self-parenting starfish often have no such male-female interaction. As a hermaphrodite, the individual produces its own eggs, which are then fertilized right inside the body, likely with that same individual’s own sperm.
How do starfish reproduce asexually?
Asexual reproduction in starfish takes place by fission or through autotomy of arms. In fission, the central disc breaks into two pieces and each portion then regenerates the missing parts. In autotomy , an arm is shed which continues to live independently as a “comet”, eventually growing a new disc and further arms.
