Europa Sea Vent Herbivore, a giant, gray, shark-like swimmer that feeds bacteria in schools with a suction cup-like mouth on an extended, Opabinia-like trunk. These trunk-shaped mouths pierce the vents to suck in vast quantities of Bacteria. These grazers are territorial and like squid on Earth, flash warning glows to drive away rivals. They make a series of dolphin-like cries.
