Scientist Francis Fraser is credited with being the first to describe a new species of cetacean based upon a single skull he found on a beach in 1895 in Sarawak, Borneo. The new species, the Lagenodelphis hosei, is named the Fraser’s Dolphin to honor the scientist, though some people call it the Sarawak Dolphin for where it is located. For most of the 20th century, the Fraser’s Dolphin was something of a mystery with no sightings by scientists since Fraser. In 1971, however, scientists from the Western world documented sightings of the species in the wild.
Fraser’s dolphins are usually found in large tight groups averaging between 10-100 individuals, but have been occasionally seen in larger groups of up to 1,000 or more animals.
