Sponges are dominant components of coral reef ecosystems, often exceeding reef-building corals in abundance. Large sponges, often more than 1 m in diameter, may be hundreds to thousands of years old. When damaged or dislodged, large sponges usually die because they are unable to reattach to the reef substratum.

20 specimens of the Caribbean giant barrel sponge were removed and reattached at Conch Reef off of Key Largo, Florida in 2004 and 2005 at depths of 15m and 30m.

Sharks are known to "dive" frequently through the water column and many functions have been attributed to the behaviour, such as thermoregulation, search and reduction of the COT. Few studies, however, have been able to frame these in conjunction with theoretical optima and test predictions for differing movement structures.

Walter Elcock, now 89 and living in Georgia, recalls the landing and how he managed to snag a wire on the carrier with the plane's tailhook and hung from it a few seconds before the wire broke.

"I went straight underwater," Elcock recalled. He unbuckled and kicked for the surface, maybe 10 feet away, thinking that he wouldn't be able to stay afloat wearing all of his heavy flight gear. Fortunately almost immediately, a Coast Guard ship pulled him out.

"I grew up hearing the story of this crash," said Elcock's grandson, Hunter Brawley, 36, of Atlanta, Georgia.

Giant basking sharks like to take tropical vacations too.

Previously thought to inhabit only temperate waters, a new study, just published in Current Biology, shows that the giant sharks make long, make vast migrations to deep, warm-water hideouts. Before the annual winter disappearance, scientists tagged 25 basking sharks off New England with floating, timed-release satellite transmitters, which showed that, like humans, the giant basking sharks like to take tropical vacations too.

The searchers were looking for another missing plane when they came upon the wreckage of a Lockheed T-33A jet trainer

The Air Force accident report identifies the pilots as Lt. Richard Martin Theiler and Lt. Paul Dale Smith. Theiler had 1,244 hours of flying experience, and Smith had 430.

Computer expert Gary Fabian is the founder of a group of unpaid volunteer enthusiasts who discovered a missing World War I German U-boat off the California coast in 2003.

Dr Jonathan Cox from the University’s Department of Chemistry has been working with researchers from the University of Cambridge and the Natural History Museum in London, testing a scale model of a hammerhead shark in a flow tank to see how the water flows around the nasal cavity of its strange flattened head.

The unique fish is called the Benguela-goby, or bearded goby, and is found only on the anoxic continental shelf outside Namibia and South-Africa. Since the collapse of the sardine fisheries, this goby has become the new predominant prey species for larger fish, birds and mammals in the region

Weighing in at up to 3,000 pounds and attaining lengths of 18 feet, Great White sharks are among the ocean’s most feared yet revered inhabitants. Having a face-to-face encounter with the ocean’s apex predator is a bona-fide adrenaline rush, with divers worldwide shelling out mega bucks and travelling great distances for the privilege.

Boasting pristine blue water with 100-foot visibility, Guadalupe Island situated west of Baja California, Mexico, is one of the world’s premier Great White destinations.
