Sea spiders can regrow body parts, not just limbs: study

Sea spiders can regrow body parts after amputation and not just limbs, according to a study released on Monday that may pave the way for further scientific research into regeneration. What the researchers discovered with their experiments with the tiny eight-legged sea spiders is that they are able to regenerate body parts other than limbs. For the study, they amputated different hind limbs and posterior parts of 23 immature and adult sea spiders and monitored the results. There was no regeneration of body parts in the adult sea spiders but some of them are still alive two years later.
