I'm developing a mild side obsession with six-gill sharks. (Hexanchus griseus) Let me tell you the features:

* Long * No dorsal fin? No wait there it is in the back * Huge doleful eyes * Murky lurkers * Just wanna eat! * Cool shape and sleek long fashionable tail

These are the best sharks. The great white is so basic. I love all graceful yet deeply awkward creatures.

What is your favorite fish?

NEW SIXGILL SHARK SPECIES UNCOVERED IN THE ATLANTIC

After decades of uncertainty, scientists have finally solved the mystery of sixgill shark species, which can be found in the Atlantic, Pacific and Indian Oceans. A new study confirms that the Atlantic sixgill sharks inhabiting in waters of Florida, Cuba and the Bahamas are actually a different and new species for science.

Previously, researchers believed to have only two known species bigeyed sixgill shark Hexanchus nakamurai and Bluntnose Sixgill Shark Hexanchus griseus. Experts have debated since the 1970s whether the individuals of bigeyed sixgill shark living in the northwestern Atlantic are actually a new species. A new study, published in the journal Marine Biodiversity, proves that it does. The sixgill sharks that swim along the coasts of Florida, Cuba and the Bahamas belong to a different species.

Atlantic sixgill sharks are actually very different from those of the Indian and Pacific Oceans, at the molecular level, to such an extent that it is obvious that they are a different species even though they are very similar to simple view. The new taxonomic classification of the Atlantic shark will allow the species to have a better chance of long-term survival

Scientists conducted molecular studies and determined sufficient genetic differences between the populations. The results thus confirm the recovery of the name Hexanchus vitulus for individuals of the Atlantic, a name given in 1969 for specimens found in the Bahamas in a study published in Bulletin of Marine Science.
