Snorkeling at Dry Tortugas National Park (around Fort Jefferson), June 29, 2010

Note: The Deepwater Horizon disaster was ongoing at the time of this visit to the Keys, and while we were there we had the feeling that what we were looking at could soon be destroyed or seriously damaged by the huge oil slick a few hundred miles to the west. Fortunately, this did not happen.

Carribean Reef Squid (Sepioteuthis sepioidea)

The sea urchin Diadema antillarum is common at Dry Tortugas, unlike the rest of the Florida Keys
Feather duster worms filter feed from their burrows inside a large Diploria coral
Large colonies of Montastrea coral are not far from Fort Jefferson
This Montastrea has a Diadema inside it
Large hollow metal blocks, probably remnants of construction of Fort Jefferson, lie in the water and corals grow on them
