4. Starfish Lifecycle Adult Starfish Fragmentation of limb
Starfish are asexual reproducers because the new organism is reproduced from a single parent.
However, not all starfish are asexual reproducers. Some species of star fish send out eggs to be fertilized by the male starfish. This is called spawning. The new embryos live in the open water amongst plankton.
Limb regeneration
Fragmented limb begins to develop star formation
