The world’s oceans have roughly 300 times more area to support life an do the world’s continents. Because greater than 75% of the deep ocean lies beneath 1000 meters, ocean depths are relatively unexplored and until recently, inaccessible. As we investigate the submarine slopes of Galápagos volcanoes we see life that no one has photographed before. The creatures that live at these depths have adapted to a way of life in one of the world’s most challenging environments.

Seamounts and Canyons

The glass-head fish even has a transparent head in which its eyes are located. To identify the new species, the research team used a variety of methods, ranging from CT scans to genetic analysis, to distinguish them from the other snailfish species. The DNA analysis and CT scans helped prove that these fish are indeed three new species.

• The deep sea fish espada is a fish tourists commonly get served by locals in Madeira, but it is actually called Aphanopus carbo and is being caught in much higher quantities by the British isles these days.
• Some whale falls can support a blanket of 45,000 worms per square meter—the highest animal density in the entire ocean.
• Many invertebrates, like amphipods, survive on the ‘food-fall’ from the surface, and, in turn, become prey for other larger species.
• The creatures that live at these depths have adapted to a way of life in one of the world’s most challenging environments.
• In addition, fish rely on their lateral line organ, which allows them to detect even the smallest changes in currents and pressure to locate obstacles or other animals moving nearby.
• This dark collar seems to mimic the silhouette of a small fish, while the rest of its body blends into the down-welling light via its ventral photophores.

A brine lake is also an area high in methane and certain bacteria can use the methane in a chemical reaction to produce energy. Animals like mussels and crabs come to feed on the special bacteria by the lake’s edge, and often there are whole communities that live along the shore. The size of the whale, the depth of the seafloor, and the location all contribute to the types of animals that colonize the area and Deep Sea determine how long it takes for the skeleton to disappear. Our knowledge of whale falls comes from few and far between ROV and AUV encounters, so though whale falls are scarce, scientists estimate they exist at every 5 to 16 km in the Pacific Ocean. The little nutrition that rains down from above in the form of marine snow is not nearly consistent enough nor substantive enough to fuel a large living creature (though there are billions of tiny ones).

• They do so by taking great gulps of air through their blow holes when they’re at the surface.
• It is also the point of transition from continental shelves to slopes.1 Despite the extreme pressure, organisms called deep sea fish can survive there.
• Hundreds of years ago the ocean perch was not a consumption fish, however – large catches were thrown overboard.
• The authors named the third species Paraliparis em after Station M, where the fish was observed, acknowledging the many scientists and staff who contribute to time-series data.
• The area of the ocean between 650 and 3,300 feet (200-1,000 m) is called the mesopelagic.

Underwater Robot Discovers Three New Species of Deep Sea Snailfish

Our specimen was collected at about 3,500m in the Porcupine Seabight in the North Atlantic Ocean in 2001. This species of Chauliodus lack scales and the pattern of the pigment forms hexagonal areas in which there is a thin deposit of an opalescent substance. However, the vampire squid does not really live up to its name since actually feeds on detritus, and does not suck blood! They are neither an octopus nor a squid and actually has its own order, the Vampyromorphida. Our specimen was collected in 1998 from the Porcupine Abyssal Plain in the North Atlantic at around 4,830m. And while for many creatures partaking in the migration is a way to avoid predators, others take advantage of the reliable movement of potential prey.

Deep sea fishing

The alteration of the seafloor will affect the chemical conditions, a new redox system would develop and an additional adsorption and mobilisation of trace elements or heavy metals becomes possible. The generally low sedimentation rates and relatively low currents lead to the effects of the collectors being visible for many years to follow. The biotrans-region, centred around 47° N, 21° W, between 3,800 and 4,600 m depth, is where the German BIOTRANS- and Bio-C-Flux-program focussed their actions between 1984 and 1993, as well as where the JGOFS-program took place. Chimney-like vents from where the hot water is expelled from the seafloor, which can be seen as so-called ‘black smokers’ in the lights of a submarine. German scientists of the 19th century also became pioneers of ocean research.
The effects on the benthic ecosystem depend mostly on the construction of the collectors, the vehicle and the depth of penetration of the entire system into the ocean floor. The sediment is being mixed, moved and relocated, as well as simultaneously re-suspending some of the sediment back into the water column. The benthic orgasms are impacted most heavily in the path of the collectors. In the 19th century Eduard Forbes postulated the lifeless ‘azootic’ zone below 500 m depths. Only with the further exploration of the deep and the capture of sea cucumbers at the telegraph cable at a depth of 1,000 metres made it evident that the deep sea is full of life. Only later, however, should the descent of a human being into the depths be possible, just as Jules Verne would have dreamt.
This dark collar seems to mimic the silhouette of a small fish, while the rest of its body blends into the down-welling light via its ventral photophores. Our specimen is the closely related Psychrolutes macrocephalus (Gilchrist, 1904) collected from depths of 1,600–1,700m in the Arabian Sea, in 2003. Our two specimens were collected from the tropical eastern Atlantic Ocean at depths between 1,060 and 1,200m, in 1993.
It also concluded that there would be indirect impacts from the formation of sediment plumes, the potential release of toxic substances and noise and light pollution (MIDAS, 2016). Thermohaline circulation plays an important role in supplying heat to the polar regions, which in turn affects other aspects of the climate system such as solar heating. The high number of mussels, up to 1750 individuals per square m, surprised most people. These mussels place their byssus in slits and take up sulphur which it then directs towards its symbiotic bacteria. The adult mussels stop using their digestive tracts and rather obtain all their nutrients through the bacteria.
In relations to protein substitution, specific osmolytes were found to be abundant in deep sea fish under high hydrostatic pressure. Not too far away, off the coast of central California, a different MBARI research team, using the submersible Alvin, found two other unidentified fish species, each dark in color. Snailfish that live in shallow waters will curl up against rocks or seaweed like snails, like their namesake. Snailfish in deep-sea trenches, on the other hand, are trickier to find, although a snailfish holds the record for the deepest-dwelling fish. Utilizing technology that was pioneered by the Monterey Bay Aquarium Research Institute (MBARI), scientists employed an underwater robot to discover three new species of snailfish.

How the creatures of the darkness have adapted to the extreme living conditions of the deep sea often appears to be spectacular. Researchers have succeeded in making fascinating video recordings of these giants. Dead giant squid have been found in fishing nets, on beaches and in the stomachs of sperm whales. MBARI’s Biodiversity and Biooptics Team observed the newly described bumpy snailfish during an expedition aboard the institute’s retired flagship research vessel Western Flyer.

The fangs on the lower jaw are so large that the fangtooth can’t close its mouth in the normal way. The fangs actually slide into specially formed pockets in the roof of the mouth when the jaw is closed. Dumbo octopuses live on or near the seabed and are most commonly seen resting or crawling on the seabed, although they can also swim. Three species were described using specimens found at the Porcupine Abyssal Plain and from within the Discovery Collections. In some species, the males are very small in comparison with the females, and live as permanent parasites on their mates.
The gulper eel has been found in temperate and tropical areas of all oceans. Although they have immense jaws, taking up about a quarter of their total length, gulper eels have very tiny teeth and actually quite a small stomach. It is more likely that the expansive mouth functions like a large fishing net.
