Due to the increasing temperature in ocean it is more advantageous for start fishes to reproduce asexually because they can regenerate via a process called fragmentation.
In fragmentation, a part of arm or a part of disc is separated from the parent body and grows into a complete new organism; an individual star fish.
Moreover, regeneration is the ability of an organism to renew, or re-grow any part of the body, makes it resilient to environmental fluctuations.
