A shark was swallowed whole by a large fish during a rarely seen deep-sea feeding frenzy
A shark was swallowed by a large fish during an infrequent feeding episode
A deep-sea video recorded by the NOAA’s Okeanos Explorer vessel traps a sea-bottom shark that savagely eats off the coast of South Carolina – and at the bizarre moment, a massive fish wreck sneaks into the sea. head on a still flickering bench intact shark in front of the camera coming out of his mouth.
It was Ocean Expedition’s Diving 07, and the ship’s explorers captured the scene with the Deep Discoverer, D2 radio-controlled aircraft. In search of a small topographic elevation, which the researchers considered a sinking, D2 floated on the ocean floor at a depth of about 450 meters.
First, a handful of sharks dive in and out of the frame when the ROV floats above a variety of ocean rocks, corals, sponges and invertebrates. At one point, he encounters a large group of sharks feeding on a dead swordfish 2.5 m long, dead at the bottom of the sea. In total, at least 11 sharks were seen by two species of deep crabs of the Squalidae family eating their skin and the muscular smorgasbord. The smallest and most numerous sharks are the genius dogfish, described only last year and named after the shark scientist dr. Genius Clark has been named.
And it’s not even the coolest part. The star of the ocean show slips casually around 1:45. The big bone-wrecked fish, also called bar or stone wolf, can be seen when a shark’s tail is moving slowly. The wrecks reach a maximum weight of 100 kilograms and are 75 centimeters long. Some are up to 70 years old.
“This is further evidence of the actual operation of these systems,” says an Okeanosteam member in the video. “Wow, I’ll remember forever!”
NOAA reports that the swordfish weighing more than 250 pounds has recently disappeared – perhaps only a few hours – depending on the quality of its body and the speed with which the sharks have eaten it. The cause of death is not clear, but it is possible that he died of old age, illness or injury. There was no visible hook or fishing line indicating that the catch had been lost. However, if the fish had been injured, the fast work of the sharks would have made it indefinable. Swordfish offers a unique learning opportunity to understand how “food scraps” work on the high seas. These occur when large pelagic species such as whales and swordfish collapse at the bottom of the ocean after their death and transfer organic carbon to the deepest parts of the ocean.
