According to CNET, scientists at the Monterey Bay Aquarium Institute (MBARI) in California found another "gem" in the deep sea, a rare bathophilus flemingi appeared in the video) . This is a kind of predator with sharp teeth. It is famous for its hunting technology of calmly hanging in the water to catch unsuspecting prey.
This week, MBARI shared this ethereal video of a torpedo like creature. This video, taken from 980 feet (300 meters) deep in the Bay, was taken by the ROV doc Ricketts (named after marine biologist ed Ricketts). ROV's lighting system lights up the fish, showing its shiny "metal" appearance. Doc Ricketts was deployed on the research ship Western flyer of MBARI.
This bronze fish has aroused people's excitement because of its rarity. "MBARI researchers have observed some different arowanas deep in Monterey Bay, but this is the rarest arowana we have ever encountered. In more than three decades of deep-sea research and more than 27600 hours of video, we have only seen this special species four times," the Institute said on YouTube
The fish only grows to about 6.5 inches (16.5 centimeters) long. The shiny appearance of this specimen is in sharp contrast to many arowanas, which are very dark in color. In their explanation of arowanas, MBARI researchers said they "have some of the blackest melanins known in nature". A 2020 study highlighted some of these fascinating fish's ultra black appearance.
For another view of bathophilus flemingi, please see the picture shared by ichthyologist Ben frable in 2020. Frable describes the fish as "having an amazing copper gold sheen in oblique light".
