Many aquarium specimens have been kept for easily 20 to 30 years. (since 80s and 90s) before being felled by starfish wasting. But these represent animals kept free from predators and regularly fed. Quality of life..from food to nutrient accessibility also likely varies. I've seen many observe predatory and other "outside" causes of death..but I have seldom if ever seen "natural causes" type deaths other than disease recorded in the literature.. I don't have any certain estimates but I would say that 35 years is pretty conservative and that there is the liklihood that starfish probably live for quite a long time...ChrisMhttps://www.blogger.com/profile/11784970666468925633noreply@blogger.comtag:blogger.com,1999:blog-3433304117507034540.post-16692132714948663882016-07-21T07:03:42.729-07:002016-07-21T07:03:42.729-07:00Do you know how long starfish live?

And "starfish" and "sea star" get applied to crinoids and brittle stars as well as actual asteroids. <br /><br />No known adult asteroids (=starfish or sea stars) actually swim. Only Crinoids are light enough and flexible enough to swim in reaction to certain predators. <br /><br />thanks for your question! I will need to address that whole "starfish" and "sea star" thing these days...ChrisMhttps://www.blogger.com/profile/11784970666468925633noreply@blogger.comtag:blogger.com,1999:blog-3433304117507034540.post-68763394047950141702011-11-02T10:33:05.971-07:002011-11-02T10:33:05.971-07:00So the so called starfish in this video (http://ww...So the so called starfish in this video (http://www.youtube.com/watch?v=MoETr8BNWLQ&feature=youtu.be) is actually a crinoid?
