Talk:Sand dollar
From Wikipedia, the free encyclopedia
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 have 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.

[edit] 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)
[edit] 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 hell no.
[edit] 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.
[edit] Too much from Cheryl Page?
It looks like a lot of this is verbatim or mildly-rephrased from Cheryl Page's Sand Dollar page. It looks to me like too much.
