Catching the

International scientists caught a fierce-looking fish with a wide mouth full of teeth while exploring the deep Australian waters.

The research team on the National Oceanographic Investigator, found a deep-sea lizard fish (Bathysaurux ferox), when exploring the 4,000m deep area of ​​eastern Australia, National Geographic reported on June 7.

"I recognized the long spinal root of Bathysaurus ferox (the other species in this family is Bathysaurus mollis with short spinal fins and very small second fin near the tail). Their large eyes and teeth are dense. The basic point is to classify predators, " said John Pogonoski of the Australian National Fish Collection.

Deep sea lizard fish are solitary species, often hunted by looting.

Deep sea lizard fish grow to about 60cm in length. In addition to the typical sharp-edged mouth, they had large dark blue eyes protruding from their heads. This fish usually lives at a depth of 1,500 - 2,400m below the surface of the water so humans rarely catch it. They are distributed in both the Atlantic and Pacific.

Deep sea lizard fish are solitary species, often hunted by looting. When the prey swims across, they rush out. Countless teeth pointed around the lizard's teeth that helped push the prey deeper into the mouth.

The source of ocean food for lizard fish is hard to find and pairing is harder to do. To maximize fertility, lizard fish evolved into hermaphrodites , possessing both male and female genitalia, allowing them to pair with any member of the swimming species across.

The international team will continue to explore deep pools of eastern Australia by mid-June. They plan to use the ocean floor survey results to better map and understand the biodiversity in the region.
