Fraser's Dolphin Q&A
What is a Fraser's dolphin?
Fraser's dolphin is a species of dolphin belonging to the genus Lagenodelphis.
They were first discovered in 1956 in Sarawak, Borneo. They are unique among dolphins for their slender bodies and short beaks. Their body is gray, with a whitish belly and a distinctive black marking around their eyes. They are named after Francis Charles Fraser, a British zoologist who first described them. They are very active dolphins, known for their high leaps from the water, spinning movements, and playful nature.

Fraser's dolphins live in the open ocean and rarely approach coastal areas.
This makes them difficult for humans to observe. Their population is not particularly large, so sightings are infrequent. They are an enigmatic species, and much about their ecology is still unknown, making them an intriguing subject for researchers.
