During asexual reproduction, a starfish can split its body in two, creating two new individuals. This process is known as fission. Fission typically occurs when the starfish is injured or stressed, and it can be a way for the starfish to regenerate lost body parts.
The number of young that a starfish produces depends on the species and the environmental conditions. Some starfish species can produce up to 200 million eggs in a single spawning event, while others may produce only a few thousand. The survival rate of starfish larvae is also highly variable, and it can be influenced by a number of factors, including predation, disease, and food availability.
