Pacific White Sided Dolphins are scientifically called as Lagenorhynchus obliquidens. These are mid-size dolphins who are found in the temperate water of the North Pacific Ocean.
These dolphins have a short snout and large dorsal fin. The Pacific White-sided Dolphins are a mix of three colours where the upper part of the fish is black, the sidelines are grey which smoothly infuses into the downside being white.
These fishes are very active and can be seen playful around the front of a ship while cruising.
