Talk:Statocyst

Bilaterians?
Bilaterians are a huge group including almost all but five phyla. When the article lists "Cnidarians, Ctenophores, Bilaterians", that pretty much includes all animals except sponges. (Well, sponges and the single extant species from the phylum Placozoa.) Referring to this as "some aquatic invertebrates" seems odd...  I suspect that the actual list of animals that have statocysts is much less inclusive than the article currently implies. Smeazel (talk) 11:54, 23 May 2011 (UTC)


 * OK, I did some digging around to find out just what animals do have statocysts, and edited the article accordingly. The list is probably not exhaustive, though, and this article could use some attention from an expert on the subject (which I am not). Smeazel (talk) 11:58, 23 May 2011 (UTC)

Can animal replace using stone?
I recall a lobster/crayfish-like creature kept in a tank that had a visible rock that I think if it fell out it would replace. That is to say, the tiny stone did not grow in the cavity but was placed there -- taken from the stones in the gravel of the aquarium. Am I remembering correctly and if so, can anyone suggest the name of the animal?--Jrm2007 (talk) 20:09, 30 May 2014 (UTC)
