Talk:Sand dollar

Is it correct to call it cloning when an immature organism divides, as was described in this article as a form of self-defence, or is this just a form of asexual reproduction?24.113.68.87 (talk) 23:03, 3 May 2008 (UTC)

I messed with the page, but i changed it back, so no worries. "When alive, the local species, Echinarachnius parma is outfitted in a maroon-colored suit of moveable spines that encompass the entire shell." Local to where? This sentence is copied from Cheryl Page's page and makes no sense in Wikipedia. -phma 22:27, 26 Apr 2004 (UTC)

This article states that by the time it has washed up onto the beach it has turned white and is dead. I havnnne discovered 2 that are quite alive. Is it possible to keep them alive at home?

They require cold sea water. Some aquariums feed them a slurry of that green algae some people drink.They Eat what

Contradiction

Is it a skeleton or is it an animal?

Both, but starting the discussion with the skeleton is wrong. I see no reason to have the sentence about one species being maroon either. That's like starting a page on vertebrates with a comment on yellow-bellied sapsuckers. Consider both fixed. --205.160.180.136 13:19, 13 April 2006 (UTC)

Is a sand dollar a fish

is a sand dollar a fish?

A sand dollar is not a fish, it is an echinoderm, quite different from a fish. And, does it look like a fish?!

A sand dollar is an organism that belongs to a group (a phylum) that is distantly related to another group (Urochordata) that gave rise to the fish eventually. So heck no. (because kids are lurking)

Yes, echinoderms include sea stars, sea urchins, and sand dollars. Fish are vertebrates. I agree with that guy.

doves?

Some info about the "doves" would be nice. I have some pictures here: [[1]]. Apparently they form the equivalent of a jaw. --CTho 02:52, 5 August 2006 (UTC) In a living sand dollar, the five "doves" fit together to form a star-shaped structure called the Aristotle's Lantern. The doves are joined by muscles that contract to bring the pieces closer together to crush sand grains. Each dove has a tooth that bisects the structure.

Please don't merge!!!

Please don't merge!! It is like merging Mallard with Duck!! :o --HoopoeBaijiKite 21:00, 18 June 2007 (UTC)

I agree, I've removed the template from both pages. The request was made by an anon user anyway. Jack 17:59, 22 July 2007 (UTC)

Pansy shell redirect

I've made a redirect page of Pansy shell to here. I hope I'm right in assuming that they are the same thing. I know Pansy shell may not be recognised as a proper name for them, but tourist areas of Southern Africa like to call them that. Jack 17:56, 22 July 2007 (UTC)

Where is their habitat?

Where does sand dollors live?
