Short summary
Oceanic rogue waves are unexpectedly large displacements from a tranquil background and pose dangers to shipping and offshore structures. A formulation of such abrupt, transient motions in the interior of the oceans is proposed. For constant buoyancy frequency, such internal rogue waves can occur in shallow fluids of various internal mode numbers, which is in strong contrast with surface rogue waves. Internal waves are crucial in oceanography as they affect transport of heat, mass and energy.
