The Fraser’s Dolphin is also called the Sarawak Dolphin after being discovered in Sarawak, Borneo. Naturalist Francis Fraser was the first to describe the species after finding a single skull on a beach in Sarawak in 1895.
Their swimming behavior is often described as low-angled, aggressive, and splashy, creating a distinctive frothy wake. Groups of individuals sometimes form long bunched lateral “chorus” lines. Depending on the geographical area, Fraser’s dolphins can be timid and elusive, or approachable and gregarious when interacting with vessels.
