Pacific White-Sided Dolphin or Lagenorhynchus obliquidens is from the coasts of the north Pacific and adjoining waters. The Pacific-white sided dolphin or Lagenorhynchus obliquidens has three colors.

The chin, throat and belly are creamy white. The beak, flippers, back, and dorsal fin are a dark gray. Light gray patches are seen on the sides and a further light gray stripe runs from above the eye to below the dorsal fin, where it thickens along the tail stock. A dark gray ring surrounds the eyes.

Pacific white-sided dolphin or Lagenorhynchus obliquidens is extremely active and mixes with many of the other North Pacific cetacean species. It readily approaches boats and bow rides. Large groups are common, averaging 90 individuals, with super groups of more than 300.

Pacific white sided dolphin or Lagenorhynchus obliquidens prey includes mainly hake, anchovies, squid, herring, salmon, and cod. They have an average of 60 teeth.

The range of the Pacific-White Sided Dolphin or Lagenorhynchus obliquidens arcs across the cool to temperate waters of the North Pacific. Sightings go no further south than the South China Sea on the western side and the Baja California Peninsula on the eastern.

Populations may also be found in the Sea of Japan and the Sea of Okhotsk. In the northern part of the range, some individuals may be found in the Bering Sea. The dolphins appear to follow some sort of migratory pattern, on the eastern side they are most abundant in the Southern California Bight in winter, but further north (Oregon, Washington) in summer.

Their preference for off-shore deep waters appears to be year round. The only known predator of the Pacific White-Sided Dolphin or Lagenorhynchus obliquidens is the killer whale.
