This discussion concerning introduction vs range extension has caused me to think of the Lion Fish that we recently saw off southern Eleuthera, Bahamas this past July and again in September.  They were seen in Winding Bay and Half Sound.  There were several seen, and one was over a foot in length.  This has to be an introduced species.  Has anyone else seen Lion Fish in the Bahamas, off south Florida or elsewhere in the Caribbean?  I'm glad Lion Fish are not aggressive.
