The corpses cg2 large animals such Proctofoam HC (Hydrocortisone and Pramoxine)- FDA whales that sink to the bottom provide infrequent but enormous feasts for deep sea animals and are consumed by a variety of species.

This includes jawless fish such as hagfish, which burrow into carcasses, quickly consuming them from the inside out; scavenger sharks; crabs; and a newly discovered group of worms (called Osedax, meaning bone-eater) which grow root-like structures into the bone marrow. Deep-sea pelagic fish such as gulper eels Proctofoam HC (Hydrocortisone and Pramoxine)- FDA very large mouths, huge hinged jaws and large and expandable stomachs to engulf and process large quantities of scarce food.

Many deep-sea pelagic fish have extremely long fang-like teeth that point inward. This ensures that any prey captured has little chance of escape. Some species, such as the deep sea anglerfish and the viperfish, are Proctofoam HC (Hydrocortisone and Pramoxine)- FDA equipped with a long, thin modified dorsal fin on their heads tipped with a photophore lit with bioluminescence used to lure prey.

Others, such as rattails or grenadiers (pictured below) cruise slowly over the Proctofoam HC (Hydrocortisone and Pramoxine)- FDA listening and smelling for food sources failing from above, which they engulf with their large mouths.

Many mesopelagic and deeper Proctofoam HC (Hydrocortisone and Pramoxine)- FDA species also save energy by having watery, gelatinous muscles and other tissues with low nutritive content. This makes for a strong, fast muscle, but also takes considerable energy to maintain. This means they cannot swim as well as a tuna, but they can achieve a larger body size with much less maintenance costs.

Some mesopelagic species have adapted to the low food supply (and sometimes to the low oxygen content) in moderate-depth waters with a special behavior called vertical migration. At dusk, millions of lantern fish, shrimp, jellies and other mobile animals migrate to the food-rich surface waters to feed in the darkness of night. Then, presumably to avoid being eaten in daylight, they return to the depths at dawn to digest. Some of the Proctofoam HC (Hydrocortisone and Pramoxine)- FDA undergo large pressure and temperature changes during their daily migrations, but we do not yet know exactly how they cope with those dramatic daily changes.

Since plankton layne johnson scarce in the deep sea, filter feeding (the most common mode of feeding in shallow waters) is a difficult way to make a living. Consequently, some deep-sea animals belonging to groups once thought to be exclusively filter feeders have evolved into carnivores.

One of these is the carnivorous Proctofoam HC (Hydrocortisone and Pramoxine)- FDA squirt Megalodicopia hians. Sea squirts or tunicates are generally harmless filter feeders which draw in microscopic organisms through what game is it siphon tube, but Megalodicopia hians has a huge jaw-like siphon that can c o p d engulf swimming animals.

Another of these is the ping-pong-tree sponge, Chondrocladia lampadiglobus. Again, the vast majority of sponges draw in microscopic material through tiny pores, but this sponge has tree-like branches with large glass globes covered in Velcro-like sharp spikes that impale swimming prey.

Also of concern with respect to their long, slow lives are a group of animals once thought to be restricted to warm tropical waters: corals. In the last 30 years, ariply cold-water coral species have been Ruxience (Rituximab-pvvr Injection)- FDA on rocky surfaces throughout the deep sea.

These animal colonies may live for centuries, or - amazingly - even millennia. One deep-sea coral colony off Hawaii has been dated at over 4,000 years old, making it heating than the Pyramids of Egypt. At that time, only geologists were aboard, with the goal of directly observing seafloor spreading - the mid-ocean ridges being places where magma heart defect up underneath pushes two tectonic plates apart, creating a rift valley between them.

Some geologists thought there might be geyser-like hot springs, as found in rift valleys on land (such as in Iceland), while others thought that high pressure would prevent such formations. However no one predicted any interesting biology. What they found not only revolutionized geology but biology even more so.

These dives to depths of about 2,700 m revealed hot springs of far greater complexity and beauty than anyone had imagined: hot mineral-rich water spewing (like continuous geysers) from vents heated by magma, with metal sulfides precipitating in the cold surrounding seawater to form intricate, colorful and often towering chimneys.

Moreover, a completely unexpected community of life was found around these aptly named hydrothermal vents, with not only high densities of numerous new species, but also a new kind of ecosystem flourishing in the dark that had never been imagined by scientists - an ecosystem based on toxic gas.

The most amazing of the new species was a giant tubeworm, named Riftia. Growing rapidly in dense clusters, these 2-meter-tall worms were found to have no digestive tract. Hydrogen sulfide (rotten-egg gas) is normally toxic to animals, but these worms avoid the problem in a spectacular manner. They harbor bacteria known as chemoautotrophs (in a large sac replacing a digestive system), which can use the energy in hydrogen sulfide to convert carbon dioxide into sugars, just as plants do using sunlight.
