A new subspecies of sea snake has been discovered off the coast of Costa Rica, and it’s got a unique hunting style that’s never been seen before in aquatic reptiles. Hanging from the surface like a coiled spring, it preys upon unsuspecting fish as they swim below.

The sea snake “opportunistically” feeds on small fish by hanging upside down in a coiled, or sinusoidal, position just below the water surface, and it only does so only at night. It’s just one of several differences that distinguish it from its closest living relative,  the  yellow-bellied sea snake, which lives in tropical waters throughout the world.  The researchers who conducted the analysis, Brooke Bessesen from the Phoenix Zoo and Gary Galbreath from Northwestern University, say the newly discovered snake may actually belong to an entirely new species of sea snake, but for now they’re content to designate it a subspecies.
