Pilot whales
often occur in very large herds and are frequently stranded
on the shore in masses. They feed on squids and fishes.
Short-finned Pilot Whales have been reported to "spy-hop,"
or perch upright in the water with just the head out.
When resting on the surface, individuals often position
themselves side by side in long lines. Their habit of
slapping their flukes on the surface is called lobtailing.
