Coelacanths are members of an order of fish that includes the oldest known living lineage of Sarcopterygii (lobe-finned fish and tetrapods). Coelacanths were thought to have gone extinct in the Late Cretaceous, but were rediscovered in 1938 off the coast of South Africa. The coelacanth has been nicknamed a “living fossil”, and is thought to have evolved into roughly its current form approximately 400 million years ago.

The reason I love diving. Well, one of the reasons at least. The colors underwater.

Salpas: Not to be confused with jellyfish, salpas are transparent, free-floating tunicates. Their gelatinous bodies swim by contracting and pumping water through internal feeding filters, feasting while they move. They can be found anywhere, but they are probably most common in the Southern Ocean, where they sometimes form enormous transparent swarms.

Railroad car sunk as part of an artificial reefThe Department of Natural Resources and Environmental Control, responsible for this programme (which was doubted at first) was successfully able to repopulate this area with fish and other marine species, thanks to the crafty use of these wagons. In fact, a 400-fold increase in the amount of plankton and small baitfish is drawing in the larger fish at such a rate that it’s a struggle to find more old subway cars to sink. The Redbird reef site began in 1996 and got its name from the “Redbird” paint-schemed subway cars donated by New York City’s Metropolitan Transportation Authority in 2001. Delaware now has 14 permitted artificial reef sites which consist of concrete structures, decommissioned military vehicles, sunken vessels, among the old subway cars.

Diane Harding It's actually a lion fish. We kill them all the time in the Caribbean because they aren't natural fish for the reef so they are in turn, destroying the reef. Pretty fish though! Tasty too!
Judy Grebeldinger You are so right, that one slipped by me, thanks!
