Latest research found out that African lungfish has the ability to walk with their fins under the water. Generally these types of fish don’t have the feet but the behavior of this fish gave surprise to every researchers. This deep sea fishes was kept at lab in the glass tanks, on observing its movement under the water they also made the studies on the land surface and researches found that Lung fish of this type can walk with their pelvic fins.
Lungfish and other so-called lobe-finned fishes are supposed to be close livelihood relations of the first known tetra pods-four-limbed animals with backbones. This study tells us that walking behaviors are not elite to tetra pods in that period and proposes that the evolutionary way to land on foot began with their finny ancestors. The result further propose that relic paths before accredited to near the beginning land tetra pods with feet or at least toe like digits may instead have been left by lobe-finned fishes touching along the waterbed.
Latest research had found that compound present in the shark’s cells has been help to fight against various viral infections. The substance which is present in the body of the shark named as “Squalamine” that is already been used for curing human eye-disorders and cancer. Now, it’s also been helpful for curing various human diseases such as dengue fever and hepatitis. It stops the virus from replicating and destroys the virus life cycle. This antiviral drug has been found by Zasloff while searching for the drug to stop bacterial diseases in deep sea sharks.
Squalamine is active against six viruses, although they also found that it does have some toxicity and other side special effects in assured cell types at dosages approximately similar to those that were necessary for antiviral efficiency. Although there is abundance of drugs to delight bacterial diseases, there are not many drugs that are effectual in opposition to viruses. Present antiviral drugs are highly exact, each one aiming presently damage of a virus, but damages can simply change and turn out to be dead set against to the drug.
The most brightly and attractive mandarin fish is belongs to the family of the dragonet. It is inhabitant to the Pacific, varying about from the Ryukyu Islands south to Australia. Mandarin fish color is blue due to its cellular pigment and they are reef dwellers, preferring sheltered lagoons and inshore reefs. It is found in the deep sea of about 1-10m from the land surface. The scientific name of these attractive deep sea creatures is Synchiropus splendidus.
Normally a nonviolent fish, but can be defensive and battle with similar species of the similar sex. It size ranges about 2-2.5 ft and it named as the most colorful fish in the world. The male Mandarin be likely to be bigger than the female and has a big sharp dorsal fin that is merely not often showed. Mandarins are tremendously sluggish and float, using their front fins while looking for food. Even Mandarins that take prepared foods have a hard time contending with quicker fish for the scraps.
Xenophyophores, single celled animal have discovered recently in the western Pacific Ocean. It was found in the long depth of ocean and it has been previously noticed in the New Hebrides Trench, south-west Pacific Ocean, at a 7500 km depth.
In western Pacific Ocean it was observed in the depth of 10,600 km below the earth’s surface. These deep sea animals are often ranges in size from 10cm in diameter. These animals contain variety of species vary widely in their appearance, ranging from compressed disks to spheres, and from angular to frilly.
The one species of these animals contains many bough tubes which is located below the earth. Xenophyophores can live in extreme cold and high pressure of ocean trench life, but are breakable and its hardly impossible to bring back again to the surface. In some place of the ocean surface 2000 species have been found 100 square meters below the earth.
The new species was discovered on a latest voyage to the Philippines and this species is named as deep-sea swell shark.
It was named as swell shark since it can swell up water and frighten predators. These species also found in the pacific and Indian ocean, according the scientist who made researches about this species.
Biologists spent 42 days on and around Philippines and found many more new species rather than swell shark.
While many of the species yet to be confirmed as new deep sea creatures using DNA or microscopes. The biologist’s team is confident that approximately 300 species are new to science.
Three new colorful species was found under the depth of Atlantic Ocean and named as Torquaratoridae –the family of acorn worms. These worms can slowly move beside the sea floor for their food which has fallen from the surface of the sea floor.
These species have no eyes or tail and were found by scientists of Aberdeen’s Oceanlab University during their trip to the Atlantic Ocean.
The new detection of small species might change the life of deep sea and also the life of evolution on the earth. New technology and advanced vehicles are helping to find new deep sea creatures day by day, the professor of Oceanlab university said.
Acorn worms are known as a scientific inquisitiveness, not noticeable holing animals that are linked to the intimates of back boned species.
They are apparent as an evolutionary deceased end, having been exceeded by their cousins; the fishes which obtain tails became fast swimmers, occupied the oceans and gave rise to reptiles, mammals and birds.
Shoals of fish are clever to move and twist in faultless configuration by next simple policy that are like those used by car drivers.
The research, which builds on preceding work presentation that fish in big groups make better decision than persons or small groups, is report in this week’s Proceedings of the National Academy of Sciences.
“Some of the most hard to believe sights in nature happen when animals form into groups and move together as if choreographed,”. Many theories have been put forward about how animals might converse in arrange to achieve this.
“But now we’re finding that it’s really, really simple,” . The researchers filmed groups of two, four or eight mosquito fish, Gambusia Holbrooki, in a square arena for five minutes, and studied the actions of persons in each group. The images of the swimming fish were fed into tracking software, which acts like many pairs of eyes to keep tabs on the way and speed of each fish in the school and how it responds to other fish around it.
The researchers used a method called artificial neural networks to look for patterns in the data.
“It turns out the astonishing coordinated swimming that fish in shoals exhibit is actually cause by each fish using very simple rules to respond to its neighbors,” said Herbert-Read.”These rules include: ‘accelerate towards a neighbor that is far away from you’ and slow down when a fellow citizen is right in front of you’.
Scientists plumb the lowest point of the Mariana Trench – the sincere part of the ocean on the planet — have recognized gigantic amoebas lurk miles and miles beneath the waters.
The creatures are called xenophyophores, and scientists from the Scripps Institute of Oceanography at UC San Diego spotted them in the cold, crushing depths 6.6 miles under the white caps.
“They are charming giants that are extremely adapted to extreme circumstances but at the same time are very fragile and poorly studied”.
Scripps scientists said xenophyophores are in the middle of the main person cells in existence, often growing longer than four inches. Recent studies indicate that by trapping particles from the water, xenophyophores can concentrate high levels of lead, uranium and mercury and are thus likely highly resistant to large doses of heavy metals. They also are well suited to a life of darkness, low temperature and high pressure in the deep sea.”The identification of these gigantic cells in one of the deepest marine environments on the planet opens up a whole new habitat for further study of biodiversity … and extreme environment adaptation,”
To reach the bottom of the ocean requires special equipment. Levin worked with Eric Berkenpas and Graham Wilhelm — Remote Imaging engineers from the National Geographic Society — to build and launch “drop cams.”
“Drop cams are versatile autonomous underwater cameras containing an HD camera and lighting inside of a glass bubble,” Berkenpas explained. By wrapping high-resolution cameras in a thick-walled glass sphere, scientists were able to drop cameras capable of withstanding the extreme pressure of all that ocean. At a depth of 6.6 miles, the water above can cause more than eight tons per square inch of pressure.
Life is surprisingly abundant at these extreme depths, despite the cold and pressure. According to Dhugal Lindsay of the Japan Agency for Marine-Earth Science and Technology, the Dropcam movie also depicts the deepest jellyfish observed to date.
Hagfish are marine craniates of the class Agnatha or Myxini, also recognized as Hyperotreti. Some researchers stare Myxini as not belonging to the subphylum Vertebrata. That is, they are the only living animals that have a skull but not a vertebral column.
