| I think your source could be incomplete. Granted, I'm going off wikipedia (http://en.wikipedia.org/wiki/List_of_long-living_organisms#Animals), but there are some obvious omissions. I'm pretty sure some sharks and other fish (eg. koi) outlive many of the animals on this list. The spiny dogfish can live over 100 years (http://www.mote.org/index.php?src=gendocs&link=Shark+Notes&category=Aquarium), and one koi is claimed to have died at 226 (http://www.fishforums.net/index.php?/topic/34936-226-year-old-koi/, but even if this age is not accurate, they can certainly live over 100 years). Finally, some clams have been found with a lifespan over 400 years (http://en.wikipedia.org/wiki/Arctica_islandica), and there's also a sponge estimated to be over 1500 years old. |
