Question

the anterior portion of the worm Eunice virids that regenerates its posterior part know as?​

Answer 1

Explanation:

Annelids are an excellent group in which to investigate regeneration abilities in a comparative context. Although annelids have the general (and well earned) reputation of having extensive regeneration capabilities, this ability actually varies widely among representatives of the phylum, ranging from species completely incapable of any regeneration such as leeches) to species capable of regenerating an entire individual from a single mid-body segment (such as some sabellids, chaetopterids, lumbriculids: Morgulis 1907; Berrill 1928; Okada 1934). Even a cursory overview of annelid regeneration abilities makes it clear that there have been multiple losses and/or gains of regeneration potential and that these losses or gains are scattered through a long period of evolutionary history.
