Detailed explanation-1: -As adults, echinoderms can regenerate many organs, including limbs, disc, gut, spines and podia and, in some species, regeneration is used for asexual reproduction2, 3. Moreover, the process has been studied extensively at molecular, cellular, tissue and ecological levels (for example, Refs 2–7).
Detailed explanation-2: -Echinoderms utilise regeneration processes at all stages of their life cycle (embryo, larva and adult). Echinoderms can regenerate body parts and even complete individual from a fragment following self-induced or traumatic amputation processes.
Detailed explanation-3: -Our human cells can do a lot of amazing things but the cells of echinoderms take it to a whole other level. Sea stars, brittle stars, and sea cucumbers all have the ability to regrow entire body parts!
Detailed explanation-4: -Some animals are known for their ability to regrow – or regenerate – body parts following dramatic injury. Starfish are among the most famous and dramatic examples, being able to grow an entire new body from just a single arm.
Detailed explanation-5: -These animals are known to undergo regeneration of various organs, including respiratory trees, longitudinal muscles, radial nerve cord, tentacles, polian vesicles, and digestive tract, among others.
