The beast regains sight in its eyes, though vision remains poor and short-sighted, and its various whiskers remain sensitive to light and vibrations. The tip of its mouth and nose harden, becoming beak-like, allowing it to continue stabbing and tearing at its prey even as its number of teeth shrink. The gill frills of females grow and harden, awkward flaps of flesh becoming more deliberate stretches of toughened skin, giving it more aerial control when the beast leaps from the water after birds. The males, meanwhile, grow smaller in size and are more seabound, preferring lower depths and less difficult prey. When the occasional female sinks underneath the mesopelagic zone, males will swarm her.
