The Pacific White-Sided Dolphin (Delphinidae Lagenorhynchus obliquidens) is ordinarily a deep-water inhabitant. They leap,  cavort, and gambol to make splashes. They migrate north in spring and south in autumn in their range and often herd up to 1,000 in groups of 40.  Black beak, flippers and dorsal fin are black, blending to white.

Killer Whale

The Killer Whale (Orcinus orca) is a dolphin but often thought of as a toothed whale. The tell-tale, tall, dorsal fin protrudes out of the water. It is large for a dolphin, but small for a whale. Resident families of Orcas live in the Northwestern waters. However, a feeding ground for sea lions and harbor seals exists at the Farallon Islands. Rogue traveling pods of these large dolphins have been spotted off the Sea Ranch coastline. While there is no real pattern to movement, May to August provides pups of both prey species along the coast, making for easy hunting by Orcas.
