This wonderful fish has 8 lines of the forces in the forehead is used during sex

The rotten ratfish does not have a deep fish, about 61 meters) in length, and indigenous in the northeastern Pacific Ocean. As if that were not enough clear description, the father of Shacha were far and put teeth in their foreheads.
While few marine animals, such as sharks, and war sharks, have structures such as dentists, changing ratfish fences, as true as those in your mouths. And they use sexually.
Investigators have shown that malachum buildings for the men arrested for the male issue may have significant effects in the history of dental events. Also, researchers now want to wonder, and what other areas can funky boost?
“The male chimaeras enhances glazed, teracula, covered in the properties such as teeth,” said research on the pedestrian pair of the PNAS. “These teeth dwells in their uncanny, and their natural evolution is not clear. We investigate the development of Teracuum and teeth in the entire Ratfish. Hydrolagus Colliei. “
Sex under hard water
The bible ratrofish stopped the teracum to intimidate the contest and hold the wings of women council while whistling. After all, it should be difficult to make love under the water without any arms. So much that these deep seabird fish have been covered with penticles-covered with penticles – to make sure their spouse does not include. When the tenacum is a brand, it is tied and blocked in lines to seven or eight lines of restored and variable. If it doesn’t work, anyy, small and white.
“This madness, a completely painful feature of long-term biology,” said Cohen Cohen, a lifeologist in the University of Washington, said in a statement. “TERACHAM is a development organization, not one unique, and the first first example of a hairless structure without jaw.”
To investigate whether tenacaculuum’s structures were teeth or genuine teeth, researchers read the teracum of hundreds of fish. They also compare fish in their ancestral fish. These methods reveal that male ratfish has grown at the beginning of the teracum, but only for men who grow up in a small white pimple (EW, not my description) reaching forehead. The building sticks with the muscles in the jaw, split on the skin surface, and teeth grow. I thank the beauty my chiefs never do that.
Tenacuum teeth based on the dental tissue – the jaw that, so far, researchers have never seen elsewhere. “When we saw the dentist for the first time, our eyes came out,” explains Cohen. “It was very exciting to see this important building without jaw.”
Real teeth
A part of the joys certainly because the denticles of the skin has no dentist, suggesting the tenacum teeth is the right one: teeth. Researchers also intensified the idea and evidence of genes, revealing the genetic symptoms linked to vertebrate teeth are expressed in Teracula. These genetic phases are not described in Denticles. In addition, the party pointed toothpopes to the types related to the types of ‘tearum in the record record.
“We have a combination of the testing data and witnessing testimony to show how these fish have filmed the production system,” said Michael Coates, a Uriversary of Chicago paper.
“Chimimeras gives a rare vision in the past,” Cohen concluded. Chimaeras is a group of cartilaginous fish, including a visible ratfish. “I think we look closely spiky franks in vertebrates, more teeth will get without jaw.”
