Epaulette shark can walk 30 metres on land and is 'evolving in climate crisis'

The epaulette shark, commonly found on shallow reefs of Australia and New Guinea, can walk up to 30 metres on dry land using its paddle-shaped fins, and survive hypoxia - a deficiency of oxygen - for up to two hours, they say.

The biologists at Florida Atlantic University (FAU), and their research partners in Australia, say these remarkable abilities enable the reef-dwelling sharks to survive increasingly hostile environments as conditions change.

The researchers' study, published in the integrative and comparative biology journal, says: "Such locomotor traits may not only be key to survival but also may be related to their sustained physiological performance under challenging environmental conditions, including those associated with climate change.
