Why the World Needs Bloodsucking Creatures | Science | Smithsonian
In a sprawling gallery of the Royal Ontario Museum, curators and technicians crowded around two large coolers that had recently arrived at the Toronto institution. Wriggling inside the containers were live sea lampreys, eel-like creatures that feed by clamping onto the bodies of other fish, puncturing through their skin with tooth-lined tongues, and sucking out their victims blood and bodily fluids. Staff members, their hands protected with gloves, carefully lifted one of the lampreys and plopped it into a tall tank. It slithered through the water, tapping on the glass walls with its gaping mouth, rings of fearsome teeth on full view.
They’re so cute!
