Iguanas Invade Gasparilla Island, Florida!
2008 Update - Fewer Adult Iguanas on the Island.

Video from my April 2008 trip to Gasparilla Island.

Boca Grande Gasparilla Island, Florida. The effort to reduce the population of black spiny-tailed iguanas seems to be working.

I've heard that about 7,000 iguanas have been killed (mostly adults). And the fact that I spotted 1 adult for every 10 or more juveniles tells me that the above statistic is probably accurate.

juvenile spiny tailed iguanas were still common on the island
This is no longer just a Boca Grande issue: Black spiny-tailed iguanas have been sighted on the mainland (I spotted 2 on the mainland just after leaving the island). Also, this species of iguana has been seen as far north as Sarasota County.

Vsit my earlier "Iguana Invasion" page for more pictures and video from my 2007 trip.

When he's not documenting prehistoric-looking reptile "invasions", Michael can usually be found in his studio creating strange sounds and then unleashing them on the internet via the Difficult Listening Channel.
