Charybdis

Backstory File: “Observing the Charybdis in action is nothing short of terrifying. Its bioluminescent streaks suggest it may use this feature to disorient prey, creating a brief flash of light before delivering a killing blow. The sheer force behind its attacks is enough to rip through reinforced glass. We've had to reinforce the observation tanks, but I fear that won't be enough if it continues to grow at this rate. It's clear now that this shark was built for the extreme environments of the abyss, but what concerns me most is how it has adapted to the confined spaces of the facility—using the architecture to its advantage, stalking us in the shadows.” – Dr. Marina Faye, Containment Report
