"The reason for why this reflex can persist after decapitation is because these are cold-water species, and the cold temperature allows tissues, like the brain, nerves, and muscle to 'stay alive' longer, before they die from lack of oxygen, and that the reflex arch from the mouth to the brain and back is unharmed by the decapitation," explained Björnsson. Wolffishes have particularly strong jaw muscles as they feed on creatures with solid shells like mussels, clams, and sea urchins. Despite its name, the Wolf Eel is neither a Wolf (obviously ), nor an. On detecting something entering the mouth, sensory nerves send signals to the brain, which then sends more nerve signals to the jaw muscles, telling them to contract.

"This is obviously a neuromuscular reflex, with receptors in the jaws and/or mouth cavity which register if anything (a prey, normally) is in the mouth," said Björnsson. So how did the fish manage to bite the can after being decapitated? This they bite down very hard with very sharp teeth, and they don’t let go. They begin life as small, transparent larvae drifting through the seas, then develop into bright orange juveniles. They live in the cold waters of the North Pacific, from California to the Sea of Japan, down to around 200 metres underwater. the contents of a bottom trawl is dumped on the deck of a trawler and the fishermen stand knee-deep in various species of fish, working on sorting and separating, an often-used routine was to stick a broom handle or similar into the mouths of the stray wolffish in the catch, so that nobody would be hurt by accidentally sticking a hand or a foot in their gaping jaws. Wolf eels are not actually eels, but are members of a fish family known as wolf fish or sea wolves. "The wolffishes have a notorious biting reflex which is well-known by fishermen," said Björnsson. "Thus when e.g. It eats crustaceans as well as mollusks, smaller fishes, and worms. "I would most definitely think that this is a spotted wolffish ( Anarhichas minor)," Professor Björn Thrandur Björnsson, head of the fish endocrinology laboratory at the University of Gothenburg, told IFLScience. The spotted wolffish is found in the North Atlantic and Arctic Oceans and can grow to almost 2 meters (6.5 feet) in length.
