One dolphin went after some unusual prey.

She is wearing a harness with a camera on her back so that researchers can watch her forage in the San Diego Bay.
She’s just one of a half dozen dolphins observed in a study published this week in the journal PLOS One.
They fitted six captive dolphins with harness cameras and recorded them swimming in three locations: the San Diego Bay, the Pacific Ocean, and in an enclosed pool.
They even captured the rapid clicks and excited squeals that dolphins make when they hunt.
Notice how she doesn’t devour the fish immediately. The dolphin repositioned the prey in her mouth in order to swallow it head first.
In the Pacific Ocean, researchers got a surprise when this dolphin went after an animal that dolphins don’t commonly hunt.
Dolphins have previously been recorded playing with sea snakes but never eating them.
Thankfully, the dolphin appeared to digest the snakes just fine.
And her strange behavior helped researchers capture the first known instance of a dolphin eating a snake on camera.
