Clearly you are one of Starro's thralls trying to make people forget the threat from this deadly land-dwelling starfish from another galaxy!Johnn Moraleshttps://www.blogger.com/profile/18410754869779549100noreply@blogger.comtag:blogger.com,1999:blog-3433304117507034540.post-83217719314657275512014-04-05T00:47:44.859-07:002014-04-05T00:47:44.859-07:00No kidneys?

Its been thought that the lack of any kind of good filtration has been key. ie. the inability to balance water with solute relative to differing habitats. Arthropods, mollusks, all have various mechanisms for tolerating these settings-kidneys, armor, etc. for water retention, processing, so forth. So far as is known echinoderms are pretty poor at managing these physiological issues. This may also be why no echinoderms occupy really prominent positions in chemosynthetic (vent or seep) habitats. <br /><br />ha! this should be a post in and of itself!

Is there anything inherent in their biology that prevents adaptation to these environments?
