Lionfish are considered the super villains of the reef because of their voracious appetites and because they have no known predators.


"Right now it's still illegal to spearfish within 100 yards of shoreline, and there are a lot of lionfish hanging out under bridges in that zone," he said.

Scientists have taken over 20000 pictures of the dorsal fins of great white sharks at Gansbaai but have identified only 532 individual sharks over a five-year period 
Image by: SHARKWATCHSA

 

The study by marine biologists from the Dyer Island Conservation Trust at Gansbaai in the southern Capefound that the total number of great white sharks might be as much as 50% lower than the previously estimated 3000-5000.

By taking more than 20000 photographs of sharks' dorsal fins over five years in Gansbaai - where the world's densest population of the species is located - scientists were able to identify only 532 sharks in the area.

 

"Marine biologists used open population statistics to extrapolate their findings [and estimated] the number of great white sharks in this densely populated area is most likely less than 1000," said the trust.

Marine biologist Michelle Wcisel, who works for the trust, said it was possible that the great white could be one of the most endangered species in the world.

Bryde’s whales are capable of extending and dislocating their lower jaw while feeding, in a manner similar to that of snakes, to encompass more foot. Their throat pleats, visible in the photos, span more than half of their bodies. This helps explain the balloon effect captured by Acevedo.

Explore the Grecian Wreck in Thunder Bay National Marine Sanctuary

In June 1906, the Great Lakes freighter Grecian struck a reef in northern Lake Huron, tearing a hole in the bottom. While being towed to Detroit for repair, the damaged vessel flooded and sank near Thunder Bay. Today, as one of the most popular recreational dive sites in the Thunder Bay National Marine Sanctuary, the Grecian rests on an even keel at 100 feet below the treacherous waves that betrayed it over one hundred years ago.

Marian Locksley's curator insight, June 11, 2013 3:11 AM

Every year tens of millions of sharks die a slow death because of finning. Finning is the inhumane practice of hacking off the shark’s fins and throwing its still living body back into the sea. The sharks either starve to death, are eaten alive by other fish, or drown (if they are not in constant movement their gills cannot extract oxygen from the water). Shark fins are being “harvested” in ever greater numbers to feed the growing demand for shark fin soup, an Asian “delicacy”.
