Hammerhead sharks dive more than half a mile below the ocean's surface to find and catch prey. And they hold their breath while they do it, according to researchers, who say...

It's an extraordinary and very surprising behavior.

Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.

To survive as they seek food in freezing parts of the ocean, hammerhead sharks use a trick that hasn’t been observed in other fish.

Hammerhead sharks like it warm, but for a good meal they’re willing to get cold.

Researchers found that scalloped hammerhead sharks showed a unique behavior of holding their breath under cold water to catch prey. Read here.

These sharks are warm water animals but feed at depths where seawater temperatures are around 40°F, yet they need to keep their bodies warm to hunt effectively.

Sharks are ectotherms and their internal body temperatures usually reflect the waters they swim in. Holding their breath helps them function in the frigid deep.

Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives according to a new study published today in Science.
