This elongated, whale-like creature moves through the water with an eel-like motion despite its wide, fluked tail. Razor-sharp teeth fill its almost reptilian mouth.

A zeuglodon can hold its breath for a number of rounds equal to 4 times its Constitution score before it risks drowning.
A zeuglodon grappling a foe can thrash its body back and forth rapidly, dealing extra damage due to the violent motion of its whipping head. This attack deals 4d8+19 points of damage, but allows the grappled creature a free attempt to escape the grapple. If a creature escapes, it is thrown 30 feet in a random direction by the zeuglodon's erratic thrashing.
