Take this tour of the wreck "Keith Tibbetts" off the N coast of Cayman Brac island in the Caribbean Sea! You'll see the adjacent reef, sand plain and wreck, with 20 years of recruitment and growth of sponges and corals on the wreck surface. One of the most interesting wrecks to dive in the Caribbean, the ship was formerly a soviet frigate that was sent to Cuba, never used, and bought by the Cayman Islands government and sunk as a dive attraction.

Coral reef rescue: Save the parrotfishes!

$Diving Looe Key, Florida Keys Change to 4K resolution if your system wont skip! Video made 7 March 2023 while diving with Captain Hooks Scuba Center of Big Pine Key. Looe Key Reef is very shallow (30 ft max depth, mostly 25 ft) with no drop off, formerly having very large live coral heads. Hard coral cover is now a small fraction of what it was in the past, but whats left looks good. Some observations: (1) Huge parrotfishes! Shows that marine park protection works! Also, schools of large blue tangs. Lots of herbivory by fishes. As a consequence, seaweed abundance is low, and pink coralline algal crusts are easily seen. Listen to the sound of large parrotfishes grazing (4:07). (2) Sea fans are thriving, no evidence of sea fan disease (aspergillosis) that was a much-discussed emerging threat in the 1990s. (3) Lots of black grouper. Small snappers and grunts hide in sea fans showing fear of reef sharks, which are present (9:30, 10:10). (4) Tragic loss of many large coral heads (4:20). But, higher coral survivorship than expected with recent SCTLD outbreaks. Out-planted staghorn corals seem to be doing well. (5) Surprisingly large giant barrel sponges for a very shallow site. (6) Despite hiding behavior of fishes, parrots and other fishes were remarkably unafraid of divers.$
