<div style="line-height: 1.6 !important; margin-bottom: 10px; padding: 0px;">
The world’s largest scaleless freshwater fish lives a tenuous existence in the murky brown waters of Southeast Asia’s Mekong River. Capable of reaching an almost mythical 10 feet (3 meters) in length and 650 pounds (295 kilograms), Mekong giant catfish live mainly in the lower half of the Mekong River system, in Cambodia, Laos, Thailand, and Vietnam.</div>
<div style="line-height: 1.6 !important; margin-bottom: 10px; padding: 0px;">
Once plentiful throughout the Mekong basin, population numbers have dropped by some 95 percent over the past century, and this critically endangered behemoth now teeters on the brink of extinction. Overfishing is the primary culprit in the giant catfish’s decline, but damming of Mekong tributaries, destruction of spawning and breeding grounds, and siltation have taken a huge toll. Some experts think there may only be a few hundred adults left.</div>
<div style="line-height: 1.6 !important; margin-bottom: 10px; padding: 0px;">
Mekong giant catfish have very low-set eyes and are silvery to dark gray on top and whitish to yellow on the bottom. They are toothless herbivores who live off the plants and algae in the river. Juveniles wear the characteristic catfish “whiskers,” called barbels, but these features shrink as they age.</div>
<div style="line-height: 1.6 !important; margin-bottom: 10px; padding: 0px;">
Highly migratory creatures, giant catfish require large stretches of river for their seasonal journeys and specific environmental conditions in their spawning and breeding areas. They are thought to rear primarily in Cambodia’s Tonle Sap lake and migrate hundreds of miles north to spawning grounds in Thailand. Dams and human encroachment, however, have severely disrupted their lifecycle.</div>
<div style="line-height: 1.6 !important; margin-bottom: 10px; padding: 0px;">
International efforts are under way to save the species. It is now illegal in Thailand, Laos, and Cambodia to harvest giant catfish. And recently in Thailand, a group of fishers pledged to stop catching giant catfish to honor the king’s 60th year on the throne. However, enforcement of fishing restrictions in many isolated villages along the Mekong is nearly impossible, and illicit and bycatch takings continue.</div>
<div style="line-height: 1.6 !important; margin-bottom: 10px; padding: 0px;">
The waters of the Mekong River are very murky and make it difficult to track the movements of the fish. In order to determine where the Mekong catfish have been, scientists examined chemical markers called isotopes in bone and muscle tissue of catfish from the Khone Falls region of the Mekong. The team found evidence that the freshwater-dwelling fish had migrated recently from a marine habitat. Although this method of fish tracking is a highly regarded method, it appears that this is the first time it has been used to track the migration routes of river catfish species from a marine environment.</div>
<div style="line-height: 23px; word-spacing: 3px;">
The recent discovery that Mekong catfish are anadromous, (moving from coastal waters into fresh waters to spawn) has surprised even scientist's long-held notions of freshwater species. It may be that many other species of catfish also have similar migration habits, and that other species of freshwater fish may be found living part of their lives at sea. It certainly gives new meaning to the concept of "freshwater fish", if they spend part of their lives living in the salty waters of a marine environment.</div>
<div style="line-height: 23px; word-spacing: 3px;">
As big as the Giant Mekong catfish can get, there are rumored to be other species of freshwater fish whose dimensions rival those of the Mekong catfish. Among them are the Arapaima and huge freshwater stingrays, both found living in the Amazon River. The giant Chinese paddlefish is also a serious contender for world's biggest freshwater fish, but very little is known about this species that seems to be rapidly disappearing.</div>

Despite their name, flying fish aren’t capable of powered flight. Instead, they propel themselves out of the water at speeds in excess of 35 miles per hour. Once in the air, their rigid “wings” allow them to glide for up to 200 meters. The wing-like pectoral fins are primarily for gliding—they hold the fins flat at their sides when swimming. Their streamlined bodies reduce drag when the fish are “flying.” If their beautiful wings aren’t enough to identify them by, another characteristic of flying fish is an unevenly forked tail. The top lobe of their tail is shorter than the bottom. 
Flying fish are up to 18 inches long but average 7 to 12 inches.It is thought that flying fish evolved a flying mechanism to escape from their many oceanic predators. Once in the air, though, they sometimes become food for birds. Young flying fish may have filaments protruding from their lower jaws that camouflage them as plant blossoms.Open ocean provides habitat for most flying fish, but some are found on the outskirts of coral reefs.Flying fish are tropical and temperate marine species that can be seen off of both U.S. coasts. They are found in the Atlantic, Pacific, and Indian oceans.Spawning takes place in the open ocean, and eggs are attached to seaweed and floating debris by sticky filaments.Some flying fish also have wing-like pelvic fins that help them to glide. These species are called four-winged flying fish.table. Flying fish are commercially fished in some places. They are relatively easy to catch because of their tendency to leap into small, well-lit boats. 
Upper side of the body of flying fish is bluish-grey. Their belly is grayish silver.Flying fish has forked tail. Lower piece of the tail is longer than upper piece. 
Pectoral fins of flying fish can be spread into wing-like shape. Certain species have pelvic fins shaped like wings also, and they look like they have two pairs of wings. 
Flying fish are shapes like torpedo. Their fins are closed when they swim to ensure faster movement through the water. 
Before it emerges above the water, Flying fish accelerates toward the surface of the water with the speed of 37 miles per hour. when requied speed is of the water with the speed of 37 miles per hour.When required speed is accomplished, Flying fish jumps out of the water and spreads its wings. 
Fling fish can reach the height of 4 feet in the air, and glide distance of 655 feet before returning back to the water. 
Flying fish can travel distances of 1.312 feet without rest. This is important because it ensures of flying fish are marlin,tuna,swordfish,mackerel and humans.  
Flying fish swims in large schools(Groups). The feature is especially appreciated by fishermen that can catch large number of fish when they bump in to a single school. 
Flying fish are very sensitive and easily attracted by the light(Fishermen use light to guide flying fish toward their ships).Despite that fact,flying fish hunts mainly during the night. 
Flying fish eats plankton,bacteria and other tiny marine creatures.Matting season of flying fish takes place when the ocean currents are the weakest.Depending on the ocean,it can be during the spring of autumn. 
Flying fish live in large groups and their number can exceed million individuals during the mating season.Females deposit large number of eggs near the surface of the water. 
Eggs are usuually attached to the floating debris. Young flying fish have whiskers near the mouths, andthey look like the underwater plants. This appearance ensures survival during the first few day of life,When the youngsters are the most vulnerable.Average lifespan of flying fish is around 5 year in the wild.

The Basking Shark Fish

It was first described by Gunnerus in 1765 from a specimen from Norway and was originally assigned the name Squalus maximus. Synonymous names include Squalus isodus Macri 1819, Squalus elephas Lesueur 1822,Squalus rashleighanus Couch 1838, Sqalus cetaceus Gronow 1854, Cetorhinus blainvillei Capello 1869, Selachus pennantii Cornish 1885, Cetorhinus maximus infanuncula Deinse & Adriani 1953 and Cetorhinus maximus normaniSiccardi 1961). The currently accepted scientific name is Cetorhinus maximus as assigned by Gunnerus in 1765. The genus name Cetorhinus is derived from the Greek, "ketos" = a marine monster, whale and "rhinos" = nose while the species name maximus is Latin, meaning "great." The basking shark is a coastal-pelagic species found throughout the world's arctic and temperate waters. In the western Atlantic, it ranges from Newfoundland to Florida and southern Brazil to Argentina and from Iceland and Norway to Senegal, including the parts of the Mediterranean in the eastern Atlantic. It is found off Japan, China and the Koreas as well as western and southern Australia and the coastlines of New Zealand in the western Pacific and from the Gulf of Alaska to the Gulf of California and from Ecuador to Chile in the eastern Pacific. The basking shark is typically seen swimming slowly at the surface, mouth agape in open water near shore. This species is known to enter bays and estuaries as well as venturing offshore. Basking sharks are often seen traveling in pairs and in larger schools of up to a 100 or more. Its common name comes from its habit of 'sunning' itself at the surface, back awash with its first dorsal fin fully exposed. Basking sharks are highly migratory. Off the Atlantic coast of North America it appears in the southern part of its range in the spring (North Carolina to New York), shifts northward in the summer (New England and Canada), and disappears in autumn and winter. Off the southwest coast of the United Kingdom in the northeast Atlantic, the basking shark feeds at the surface of coastal waters during the summer. These sharks are absent from November to March, suggesting a migration beyond the continental shelf during the winter months. This is explained by the high zooplankton density (the primary food of the basking shark) that exists in these waters during late spring and early summer. Sightings of groups of individuals of the same size and sex suggest that there is pronounced sexual and population segregation in migrating basking sharks. Along with the whale shark and the megamouth shark (Megachasma pelagios), the basking shark is one of three species of large, filter-feeding sharks. However, the basking shark is the only one that relies solely on the passive flow of water through its pharynx by swimming. The basking shark is usually seen swimming with its mouth wide open, taking in a continuous flow of water. The whale shark and megamouth shark assist the process by suction or actively pumping water into their pharynxes. Food is strained from the water by gill rakers located in the gill slits. The basking shark's gill rakers can strain up to 2000 tons of water per hour. These sharks feed along areas that contain high densities of large zooplankton (i.e., small crustaceans, invertebrate larvae, and fish eggs and larvae). There is a theory that the basking shark feeds on the surface when plankton is abundant, then sheds its gill rakers and hibernates in deeper water during winter. Alternatively, it has been suggested that the basking shark turns to benthic (near bottom) feeding when it loses its gill rakers. It is not known how often it sheds these gill rakers or how rapidly they are replaced.

he basking shark gets its name due to being slow moving and enjoying time basking in the sun. It is strange to researchers to see such a large shark so close to the surface though. The basking shark is the second largest shark found in the world. They do move to deeper water in the winter months though.Sometimes the basking shark is seen jumping out of the water. It is an amazing sight to see due to the sheer size of them. Researchers believe this is done in an effort to remove as many parasites from the body as possible.It has an extremely large liver, bigger than most species of sharks. The liver is believed to be ¼ of the overall body weight. This liver not only stores oil to help reduce the need to feed but it allows the basking shark to have plenty of energy all the time. They are one of the few species of sharks that form groups as most sharks are loners. The group may only have a few members or it can have up to 100. The larger sized groups are very rarely found though.</div>

The monster fish is called a goonch and can grow to six foot, regularly weighing more than 11 stone.It lives in the Great Kali River, between India and Nepal - a stretch of water which is often used to dispose of human bodies after Hindu funeral rites.Some think this may have lead the goonch to start poaching live human victims.Biologist and expert fisherman Jeremy Wade decided to delve beneath the surface of the Kali River to track down this mysterious beast for a Channel Five documentary.He said: "The locals have told me of a theory that this monster has grown extra large on a diet of partially-burnt corpses."It has perhaps got this taste for flesh by feasting on remains of funeral pyres."There will be a few freak individuals that grow bigger than the other ones and if you throw in extra food, they will grow even bigger."Mr Wade managed to snare one goonch which weighed 161lb and was nearly 6ft long - the biggest of its species ever caught.He said: "If that got hold of you, there would be no getting away."The goonch is thought to be responsible for the disappearance of an 18-year-old Nepali last year, who was dragged under the water by a creature described as a "elongated pig".Two earlier mysterious river deaths are also considered to be the work of the killer fish.</div>

Weird Gramma here with “WeirdFins,” all about strange stuff in the sea, and brought to you by the National Oceanic and Atmospheric Administration. My neighbor says she saw a picture of a fish called a blobfish that looks just like her Uncle Walter, and wonders if there are other kinds of blobfish that look like other people. Well, no, all blobfish look pretty much like my neighbor’s Uncle Walter. And it’s probably not a good idea to tell Uncle Walter that the blobfish belongs to a group of fishes called fatheads.</div>
<div style="line-height: 20px; padding: 5px 0px; text-align: justify;">
This is one of the funniest fish faces in the ocean, although you’re not likely to see a blobfish since they live in very deep water off Australia. In fact, it’s pretty rare for anyone to see blobfish, although they’re sometimes taken in nets hauled in by Australia’s deepwater fishing fleet. They really do look like a big, blobby tadpole, just a mass of pale, jelly-like flesh with puffy, loose skin, a big nose, and beady, staring eyes. But looking like a floppy water balloon is what actually helps the blobfish make a living. This guy just sort of floats above the sea floor so it doesn’t have to spend a lot of energy swimming around, sort of like when you float in the water wearing a life jacket.</div>
<div style="line-height: 20px; padding: 5px 0px; text-align: justify;">
Blobfish seem to grow only to about 12 inches, about as long as a comic book. No one has seen them feed, but scientists think blobfish probably just open that big mouth and let little particles drift in—this is not a critter built to chase down its food.</div>
<div style="background-color: white; border: 0px; line-height: 26px; margin-bottom: 10px; padding: 0px; vertical-align: baseline;">
The blobfish, charmingly described as "hideous" by the Ugly Animal Preservation Society, has been awarded the dubious honour after repulsing people with its jelly-like appearance in the sea off the coasts of Australia and Tasmania.Milky-white in colour, the blobfish can measure up up to a foot in length and dwells between 600 and 1,200 metres below the sea's surface.But despite being attractive, not to mention completely inedible, the species has a habit of being hauled up by fishermen's trawler nets and is thought to be under serious threat.Simon Watt from the Ugly Animal Preservation Society said: "We've needed an ugly face for endangered animals for a long time."For too long the cute and fluffy animals have taken the limelight but now the blobfish will be a voice for mingers who always get forgotten."Describing the species, Mr Watt added: "Indeed this is an ugly hideous thing. It looks sad and so it should, because it's suffering from severe problems."They've got a really gelatinous flesh that is slightly more buoyant than the water. So they float around and they can be right lazy."They've got no muscle tone whatsoever because they don't have to move. They just sit there looking unhappy, grabbing any food that comes by."It's the ultimate deep sea couch potato."The blobfish topped an online poll of five ugly animals voted for by the public, beating the critically endangered giant parrot the Kakapo and a Mexican salamander that is the equivalent of a giant tadpole, called the Axolotl.Also on the list was the Titicaca water frog - found in Lake Titicaca on the border of Peru and Bolivia and dubbed the "scrotum frog" - and the proboscis monkey, from Borneo, whose enormous nose is used to make its deafening mating calls.The Ugly Animal Preservation Society was founded to champion the cause of endangered creatures with no friends, and has been backed by a number of celebrity scientists, presenters and comedians.</div>

In 1989, I had the unique opportunity to conduct seabird surveys aboard the NOAA research ship McArthur during a tuna-porpoise research cruise. The seabird counts were to supplement the focused cetacean surveys undertaken by two teams of 3 mammal observers, who used 25X 'big eyes' mounted gyroscopic binoculars (as shown to the left; Gary Friedrichsen in harness). These wide-ranging surveys in the eastern tropical Pacific from 1986-1990 provided evidence that porpoise numbers were declining due to tuna fishing methods. There is a close association between tuna and groups of porpoise that forage just above them (and also Sooty Terns and other tropical seabirds with the dolphin). Two NOAA ships — the McArthur and theDavid Starr Jordan — each spent four months at sea, stopping for breaks only once a month. During my 120 days at sea, standing seabird watches 2 hours on, 2 hours off, every day dawn to dusk, provided a wealth of experience with both tropical seabirds and tropical cetaceans. While my surveys were with ordinary binoculars and involved counting birds within 300 m of the ship, I did move to an extra pair of 'big eyes' whenever pods of dolphin were encountered and the ship turned off its transect to catch up with them for standardized counts. My job in those times was to identify and count the flock of birds that is always with those tuna-porpoise assemblages. 
Can Dolphin talk? Maybe they can't talk with words, but they talk with sounds. They show their feelings with sounds. 
Dolphin travel in a group. We call a group of fish a"School". They don't study.but they travel together in a school.Dolphin talk to the other dolphins in the school.They give information. They tell when they are happy or sad or afraid. The say "Welcome"when a dolphin comes back to the school.They talk when they play.They make a few sounds.above water.People can not hear these sound because they are very,very high.Scientists make tapes of the sounds and study them. 
Sometime people catch a dolphin for a people can watch the dolphins in a show.Dolphin don't like to be away from their school in an aquarium.They are sad and lonely. There are many stories about dolphins. They help people.Sometime they save some body's life. Dolphin meat is good, but  people don't like to kill them.
