Blue Shark

by dsc.discovery.com

Beautiful and elegant are not words often associated with sharks, but they seem appropriate for the sleek blue shark. Its streamlined, indigo-blue body seems to move effortlessly from the surface to the deep sea that it favors. Its large pectoral fin and other appendages help with navigation, but its secret to buoyancy is a giant, oil-filled liver. This makes it easier for the shark to travel incredibly long distances. One tagged blue shark traveled from New York to Brazil, a distance of over 3,740 miles.

Porbeagle Shark

by dsc.discovery.com

Many sharks and other fish prefer warm water, but porbeagle sharks like to stay cool. They inhabit coastal regions and the open sea. Like shortfin mako sharks, porbeagles possess a body heat regulatory mechanism that can raise their temperature several degrees higher than that of the surrounding water. As a result, they function efficiently in the freezing water off the coasts of Iceland and Chile. This stocky shark is often included in studies on whether or not sharks play. That is because several observers have reported seeing porbeagles in groups of up to 20 individuals manipulating and tossing about floating objects, including lumber and seaweed. They seem to engage in such activity for no apparent reason other than to pass the time.

Lemon Shark

by dsc.discovery.com


Lemon sharks may dive up to 1,300 feet when searching for food, but usually they are found near shore areas at depths closer to 295 feet. Their unusual coloration sets them apart from most other sharks. “Lemon” refers to their light brown, yellow-tinged skin. It provides good camouflage for the sharks, which like to rest over the sandy bottoms of shallow water regions. From a distance, it is hard to tell where the sand ends and the shark begins. One clue might be the presence of small reef fishes, such as wrasses, which gather around this shark to pick off parasites from its gills and skin. This species is most commonly found in the Caribbean, but it also exists in the western and eastern Atlantic and eastern Pacific from southern Baja California to Ecuador.


Basking Shark


by Wikipedia

The basking shark, Cetorhinus maximus, is the second largest living shark, after the whale shark. It is a cosmopolitan species — it is found in all the world's temperate oceans. It is a slow moving and generally harmless filter feeder.

Like other large sharks, basking sharks could some day be at risk of extinction due to a combination of low resilience and overfishing if good conservation practices are not followed.


Mola Mola



The ocean sunfish (mola mola) is the largest bony fish in the world. It is a unique pelagic fish, and specimens of ocean sunfish have been observed up to 3.3 m (11 ft) in length and weighing up to 2,300 kg (5,100 lb).

In Indonesia, precisely in Nusapanida Bali mola mola fish there that are large, the following video:

Mekong Giant Catfish

A 646.2-pound Mekong giant catfish, netted in Thailand, may be the largest freshwater fish ever found. The fish was documented as part of a World Wildlife Fund-National Geographic project to identify, study and conserve freshwater fish around the world that exceed 6 feet in length and 200 pounds in weight.

Elephant Butte Reservoir can get fairly deep - around 80 feet near the dam - deep enough for sunken boats to stay sunken, for enormous fish to stay hidden and for stories of such fish to remain nearly impossible to confirm.

These stories, told by fishermen, fishing guides and locals, tell of enormous catfish - catfish ranging in size from the slightly terrifying to the utterly panic-inducing.

The stories say catfish around the base of the dam are like freshwater whales, growing as big as their massive aquarium will let them, and eating whatever the upper Rio Grande and its tributaries wash down - other fish, plants, swimming dogs, decomposing human bodies and even the occasional small deer that ventures too close to the water.

"Basically, from what I understand, just below the dam there's just some really old catfish the size of you and I," Young's Water Sports owner Bo Young said. "I never witnessed it myself, but it's certainly feasible. Catfish do get pretty big."

Frank Vilorio, an employee at Land of Enchantment Fishing Adventures, said divers repairing a wall of the dam saw several large catfish.

"They compared one of those catfish to a Volkswagen bug with the hood open," Vilorio said.

John Morlock, a semi-retired Elephant Butte fishing guide, said he once knew a woman who swore she knew divers who had been in the water and seen enormous whiskered catfish the size of school buses - catfish so huge and so frightening that one of the divers never re-entered the water.

The New Mexico state record for the largest catfish ever caught was set at Elephant Butte in 1979. That catfish weighed 78 pounds and was almost 4 feet long. It was huge, but it wasn't bus-sized.

Stories of giant catfish aren't unique to New Mexico or to the present.

Father Jacques Marquette wrote about a gigantic catfish ramming his canoe on a Midwestern river in the late-1600s. A Protestant missionary, on the Ohio River in 1780, relayed the story of a catfish pulling a man from a riverbank to drown and then eat him. Mark Twain wrote a fictional account of catching a more than 6-foot-long one in The Adventures of Huckleberry Finn.

"Others are quite current, including the persistent rumor of a large flathead (catfish) caught at the mouth of the Tradewater River on the Ohio, by Caseyville, Kentucky, which contained a human baby," wrote Jan Harold Brunvand in American Folklore: An Encyclopedia. "This supposedly occurred during the 1970s. ... Many river folk believe that very large catfish, hardly ever encountered by fishermen, live in deep holes in the river for decades. There are also legends of huge catfish living at the bases of dams, who prey on divers inspecting or performing maintenance."

Such stories pop up all over the country in countless rivers and lakes and reservoirs, often with details startlingly similar to the ones from Elephant Butte - but this shouldn't make us think any less of our stories.

Our stories may be unproven. They may lack physical evidence or firsthand witnesses, and they may have every hallmark of an urban legend, but they do have one thing going for them: Nowhere else in America are the fabled catfish ever so big.

Ours are bigger than all of them, even if they are probably just as fictitious. Catfish the size of cars just aren't sufficient for New Mexico. We need them bus-sized.

And we shouldn't stop at that, either.

"I heard there was a two-headed fish caught out there," Young said. "A bass."
