Wholphin: a fertile hybrid
|
view preview
A wholphin is a rare fertile hybrid born from mating a bottlenose dolphin ( Tursiops truncatus) (mother), and a false killer whale ( Pseudorca crassidens). Although they have been reported to exist in the wild, the first captive wholphin was born in 1945, where a bottlenose dolphin and a male false killer whale shared a pool. The wholphin's size, color and shape are intermediate between the parent species. For example, an adult wholphin has 66 teeth - intermediate between a bottlenose (88 teeth) and false killer whale (44 teeth). They are smaller than a false killer whale but are larger than a normal bottlenose. Normally, when two different, yet similar species mate, such as a female horse and a male donkey forming a mule, the progeny is expec ...

The ghost fish has been captured on video for the first time
|
view preview
A living, swimming ghost fish has been seen live for the first time ever. The fish, part of the family Aphyonidae, was caught on camera during an ongoing National Oceanic and Atmospheric Administration (NOAA) exploration by the ship Okeanos Explorer. The exploration centers on the deep ocean at Mariana Trench Marine National Monument, a protected area spanning 95,216 square miles (246,608 square kilometers) east of the Philippines. The secretive fish was swimming along a ridge 8,202 feet (2,500 meters) down, according to NOAA. The animal is about 4 inches (10 centimeters) long, with translucent, scale-less skin and eerie, colorless eyes. No fish in the family Aphyonidae has ever been seen alive before. ...

Super strange spider found off Antarctica
|
view preview
Collected from the Ross Sea shelf in southern Antarctica, this 9.8-inch-long (25-centimeter-long) giant sea spider was one of 30,000 animals found during a 35-day census in early 2008. The marine arachnids, which prey on hydroids and bryzoans - branching, coral-like animals - are larger and more common in Antarctic waters than anywhere else on Earth. Cold temperatures, few predators, and high levels of oxygen in seawater could explain their gargantuan size.

The ocean is louder than you think

Nearly 11 kilometers deep, the ocean is still a noisy place, according to scientists that have eavesdropped on the deepest part of the world's ocean, and instead of finding a sea of silence, discovered a cacophony of sounds both natural and caused by humans. For three weeks, a titanium-encased hydrophone recorded constant ambient noise from the ocean floor at a depth of more than 36,000 feet, or 7 miles, in the Challenger Deep trough in the Mariana Trench near Micronesia. The ambient sound field is dominated by the sound of earthquakes, both near and far, as well as distinct moans of baleen whales, and the clamor of a category 4 typhoon that just happened to pass overhead. The hydrophone also picked up sound from ship propellers. Challenge ...

Glow-in-the-dark shark

Meet the ninja lanternshark. It's a newly discovered animal that's really weird. It hides in the deep - and its black skin keeps it camouflaged - but it also glows in the dark. The ninja lanternshark was discovered by a team at the Pacific Shark Research Centre, in Moss Landing, California. Its official Latin name is Etmopterus benchleyi, after Jaws author Peter Benchley. The ninja lanternshark is roughly half a metre, or 18 inches long, and it lives at a depth of about 1,000 metres off the Pacific Coast of Central America. Its odd combo of dark and light helps it creep up on its prey, according to its discoverers. ...

These flashes may also serve to illuminate the prey to make for easier capture as well as a courtship and territorial display.

Cookie monster of the sea

The cookie cutter shark ( Isistius brasiliensis) is as fearless as they come! This small, 20-inch shark can take on giants like whales and larger sharks, and have even been known to mistakenly try to bite submarines. They dwell in the deep warm ocean and come closer to the surface as the sun sets to grab a quick snack off their unsuspecting prey. Cookie cutter sharks approach their victims from below, latch on with their suction cup style lips, bite and then twist (below). A nice, round hole is left as a souvenir. They get this easy meal by tricking other ocean residents with their distinctive brown collar, which may act as a lure that allows the cookie cutter shark to be seen as a smaller, not-so-scary fish. As frightening as they seem, the ...

The culling policy aims to reduce shark attacks by killing white, bull and tiger sharks over 3 metres long off the coast of Western Australia. Research on previous culls reveal no scientific evidence that destroying sharks reduces attacks, and the cull has caused outrage from conservation groups. Two experts from the University of Western Australia explain: "Pre-emptively killing sharks is a response based on emotion rather than of scientific data."

A flying fish moves its tail up to 70 times per second to propel itself up and out of the water. Those specialised pectoral fins are spread wide and tilted slightly upward to provide lift, and then folded back against the body to lower the fish back into the ocean. Flying fish (family: Exocoetidae) are eaten by dolphins, tuna, birds, squids and porpoises, so they needed to develop an ingenious mode of escape - such as flying - in order to survive.

Generally dark gray to dark brown in color, they have huge heads and enormous crescent-shaped mouths filled with sharp, translucent teeth.

Baby stingrays

Stingrays are ovoviparous, meaning that the eggs develop and hatch inside the mother, who then give birth to live young. They have between 5 and 13 offspring at a time. Before birth, the female holds the embryos in the womb without a placenta. Instead, the embryos absorb nutrients from a yolk sac, and after the sac is depleted, the mother provides uterine "milk". Two female stingrays at the London Aquarium have given birth to young in spite of the fact that they haven't been near a male in more than two years. Therefore, it stands to reason that female stingrays have the ability to store sperm in some way. ...

The coelacanth is known as a “living fossil” because it looks very much like its ancestors from 300 million years ago. Its genome has been sequenced, and it, in fact, has been found to be evolving at a very slow rate. The genetic sequence also might help give some insight into the transition from fins to limbs.

To kill or not to krill?
|
view preview
Without krill, most of the marine animals in Antarctica would disappear. So what are they?Krill are crustaceans, each about 5 cm long. In addition to their diet of phytoplankton, they have the ability to scrape ice-algae from the underside of ice formations. In turn, they are on the menu for hungry squid, penguins, seals and whales. In short, krill form an integral part of the Antarctic ecosystem. Together, krill would number in the billions, yet their numbers are decreasing. Why? One reason may be the melting and loss of ice formation due to increased global temperatures. Another reason is humans' greed. Krill oil, high in omega-3 fatty acids, is packaged as health medication to maintain healthy cholesterol. How many krill are worth the lif ...

The flipping ship
|
view preview
The FLIP ( FLoating Instrument Platform) ship is an open ocean research vessel designed to partially flood and pitch backward 90 degrees, resulting in only the front 55 feet (17 metres out of 108 metres) of the vessel pointing up out of the water, with bulkheads becoming decks. When flipped, most of the buoyancy for the platform is provided by water at depths below the influence of surface waves, hence FLIP is a stable platform mostly immune to wave action. At the end of a mission, compressed air is pumped into the ballast tanks in the flooded section and the vessel returns to its horizontal position so it can be towed to a new location. ...

The wolphin is the extraordinary result of breeding a female bottle-nosed dolphin with a male false killer whale. In captivity there are two occurrences, both are in the Sea Life Park in Hawaii. Unlike other hybrids, the wolphin is fertile.

A white-blooded ice fish
|
view preview
This is a white-blooded ice fish, or "crocodile fish" ( Chaenocephalus aceratus). They lack both red blood cells and hemoglobin, and so have white blood. They have translucent bodies, and absorb oxygen directly from the water around them.

The giant squid once faced a population bottleneck
|
view preview
Genetic testing of giant squid corpses discovered all over the world has found that not only are they all the same species, they have surprisingly low genetic diversity. This suggests that some time in the recent past they were pushed to the brink of extinction, but managed to rebound and are now found throughout the worlds oceans.
