When an Eel Climbs a Ramp to Eat Squid From a Clamp, That’s a Moray
The New York Times
Moray eels can hunt on land, and footage from a recent study highlights how they accomplish this feat with a sneaky second set of jaws.
In the video, forceps nudge a piece of squid that sits on a ramp as an offering. Suddenly, a snowflake moray eel named Qani heaves its muscled bucatini of a body out of the water and onto the ramp. It opens its mouth and bites the squid. The eel pauses a moment, opens its mouth again and, as if its tongue were a conveyor belt, sucks the squid even deeper into its mouth using a secret second set of jaws in its throat. This particular eel mukbang, to Rita S. Mehta, an evolutionary biologist at the University of California, Santa Cruz, was cinematic gold: footage that showed the bite, the prey transport with secondary jaws and the swallow. Her team had taped loads of footage of the eels feeding on the ramp, but none that showed the act from beginning to end. Dr. Mehta first described the moray eel’s second set of choppers, known as pharyngeal jaws, in 2007. When a moray hunts, it seizes its prey with the teeth of its outer jaw, and then its pharyngeal jaws leap forward out of the throat and into the mouth to grasp the prey and drag it deeper into the eel’s body.
