The Epaulette Shark!
Fun Fact: The Epaulette Shark has the ability to survive low oxygen conditions by the switching of non-essential brain functions, which is helpful when hunting in tide-pools with low oxygen!
Shark Fact
Epaulette sharks, a small type of reef shark, can "walk" on land during low tides. They do this by their pectoral and pelvic fins evolving to be more like feet so that they can crawl outside of the water from pool to pool during low tide.
They are able to lower their hearts and the rate at which they need to breath to be able to go outside of the water.
Walking on land allows for better hunting as well as to move to more oxygenated pools of water.
