PLUNGER("Alternative Evolution" of Dinosaurs) The plunger is a fishing pterosaur that has lost its powers of flight. Its wings are still present but modified into hydrodynamic organs that allow it a mobility in the water that its ancestors had in the air. Layers of fat have built up under the skin, and these not only insulate the animal from the chill waters but also give it the streamlined shape that allows it to swim easily. The plunger’s lungs have special adaptations to withstand the great pressures found at the depths at which they hunt their food.
