Another correction

Well it turns out that the cuttlefish picture I posted is not a cuttlefish at all.  What we observed and photographed is a Sepioteuthis sepioidea, or Caribbean Reef squid.  More information and some good pictures here: http://www.thecephalopodpage.org/Ssepioidea.php.  The name is not nearly as interesting, but the squid were still fun to watch and look pretty cool.  They do change their color like the cuttlefish which means we have enormous latitude for adjusting the pictures in Photoshop - we can't get the color wrong because they change color all the time anyway!
