They discover a species of shark that is able to walk and survive for hours without oxygen

And walking shark The recently discovered one that breaks all the laws of existence is the focus of a study by Florida Atlantic University and Associates in Australia, They investigated how walking and swimming changed in early development epaulette shark,

this little benthic sharkwho lives in the rocks, moves in and out of water by moving its body, which it pushes with its paddle-shaped wings, able to survive without oxygen for two hours without any adverse effects already a much higher temperatures than most hypoxia-tolerant animals,

Their ability to move in these challenging environmental conditions may affect their survival and their physiological responses Climate change and was found within the rocks, around Great Barrier Reef, Australia,

However, very few studies have examined them. body movements, Whereas existing research focuses only on the stages of adult life. So far no study has considered its movement in the early stages of its life.

researchers of FAUwith the support of James Cook University and Macquarie University of Australiathey checked difference between walking and swimming In newborn and young walking sharks. Newly born maintain the nutrition of the embryo by an internal yolk sac, while teen They are slender as they actively seek out insects, crustaceans and small fish.

results published in the journal Integrative and Comparative Biology showed that the difference in body size did not alter the kinematics between nascent and juvenile walking sharks, Overall speed, fin rotation, axial bending, tail-beat frequency and amplitude were consistent in early life.

the figures show that locomotive kinematics Newborn and juvenile epaulette remains between sharks even when feeding strategy changes. These findings suggest that submerged locomotion in newborns not affected From the effects on the yolk sac and body size, as all aspects of submerged locomotion were similar to the young.

“Studying epaulette shark locomotion allows us to understand the ability of this species, and perhaps related species, to move in and out of the challenging conditions of their habitats.”Told Marian E. Porterlead author and associate professor Department of Biological Sciences at FAU,

“In general, these are important for locomotor symptoms” existence of a small benthic mesopredator They maneuver in small rock crevices to avoid aerial and aquatic predators. These symptoms may also be related to their physical performance sustained under challenging environmental conditions, including those associated with climate change, is an important topic for future studies,” he said.
