Exploring the ocean depths off the coast of Australia, scientists have discovered as many as 30 new marine species, including, perhaps, the longest animal ever discovered by man. During the expedition in the submarine canyons of Western Australia researchers have found millions of siphonophore (Siphonophorae) – deep sea predators that belong to the order flowing down and form a colony with the overall body, which is called zenosearch. It is noteworthy that in every anasarca contain hundreds or thousands of individual creatures Zohidov. Most colonies siphonophores can reach several meters in length, and the body was found belongs to the species of Apolemia and a length of about 47 meters.
The expedition Ningaloo Canyons, which was directed by (SCI), has joined an international team of scientists, who studied the poorly understood, but biologicheski rich part of the ocean off the coast of Western Australia. The underwater remote-controlled apparatus, the DWARF in the course of the expedition have been discovered such deep-water animals like, squid-octopus, long-tailed sea cucumber, glass sponge, and, of course, the first huge colony of animals, like an upside down jellyfish – a huge siphonophore. The researchers suggest that most species were previously not known to science.
Led an expedition Nerida Wilson, senior researcher at the Western Australian Museum. quoted her words about the fact that the extra-long opening of siphonophora occurred at a time when aboard least expected. The DWARF dived to a depth of 4 439 meters, but siphonophora found when the surface was only 630 meters.
Most of the colonies siphonophore that I saw was a length of about 20 centimeters, with a maximum meter. But this animal is not just massive, the colony shows an amazing behavior: hunting is.

most Likely all kinds in front of you – not known to science.
Discovered siphonophore approximately twice as long as many blue whales and three times the length of the humpback whale, which typically reaches a length of up to 15 meters. By the way, up to the discovery of a giant siphonophore the longest independent body was considered a jellyfish, which is called “lion's mane” as a large specimen – due to the lush tentacles can reach a length of 37 meters. Second place went to the blue whale and a maximum of 33 meters. However, the longest living organism on Earth is a tapeworm extracted from the intestines of the sperm whale: the length of the parasite has reached over 50 meters. The absolute record.
If you look closely at siphonophora at first it may seem that it is just a big animal, but before you – billions of individuals forming a single unit. These organisms are always “cloned” themselves, creating new Zohidov. In this case, each of them different tasks – some spetsializiruyutsya on the decoy food, and the others in the movement or reproduction. Eat siphonophore like a jellyfish with dangling in the water stinging tentacles. With their help, the colony paralyzes and pulls on the massive “body” small crustaceans and fishes that are not fortunate enough to swim in this forest of poisonous tentacles.
an international group of researchers and oceanographers were able to capture really large colony
All the nutrients Zooey pass along the “stem” or rod, which is attached and which is for them something like the nerve endings of the conductive signals. It is the process of absorption of food managed to shoot with the DWARF. Information about these creatures too little, but we know that all the resources within siphonophora are distributed according to the known principle “from each according to ability, to each according to need”. As for the spiral shape of the animal, which was caught on camera, then it indicates the process of feeding. Agree, just incredible.
It is Important to note that the opening of siphonophora and other likely previously unknown to science species was done in the protected area known as the coast Gascoigne. As the researchers note, although it is a protected area, they don't know which species live there. The discovery is striking because the researchers were able to show the incredible biodiversity in this region. Nevertheless, Wilson admits that it may take months or years before scientists are 100% confident in the fact that they discovered the organisms are new to science.
