    Scientists conduct first study on the largest known marine stingray

    June 17, 2019 - This smalleye stingray is the largest marine stingray on record. Due to the elusive nature of these stingrays, scientists know very little about their ecology and behavior. This footage was captured off the coast of Mozambique, which is a popular dive spot for recreational scuba divers. Scientists put out a call for all tourists who have filmed or photographed this species to send in their photos for data collection. Through crowd-sourcing, they were able to come out with the first study on the world’s largest marine stingray. By identifying spot patterns on the back, they were able to track surprisingly long migration patterns. They proved to have the longest straight-line distance ever recorded by a stingray of the whiptail family. Because of the limited data, their conservation status is unknown. But scientists hypothesise that their numbers are low and hope that this new study will help to protect the species.

    Watch flatfish 'walk' using finger-like fins

    This 'walking' rock sole fish has an unusual way of moving. Flatfishes, including flounder, sole, and halibut, live on the seafloor and eat small bottom-dwelling animals. To move forward, flatfish bunch up a few fin rays to form a 'fin-foot'. In a wavelike sequence, the 'feet' move the fish across the seafloor. The movement is just one way these fishes have adapted to life on the seafloor.

    Scientists React to Bizarre Deep-Sea Fish

    Scientists on the Nautilus team ran into a mysterious creature on a recent expedition in Hawaii. The strange fish was found nearly a mile beneath the surface. The colour commentary from the scientists is priceless. The fish is called a gulper eel. Its pouch-like mouth can inflate to swallow very large prey. This is a particularly young eel; adults can be up to one metre (three feet) long.
