Fraser's dolphin's scientific name is Lagenodelphis hosei.
The generic name, Lagenodelphis, is derived from the
Greek lagenos, meaning "flagon". The specific name,
hosei, is named for Dr. Charles Hose (1863-1929).
Hose was a British naturalist stationed in Sarawak, Borneo
1884 to 1907, discovering the skull of this dolphin on a
beach in 1895. Interestingly, this species was not
described until 1956, or even observed alive until 1971.
The common name is named for Dr. Francis Fraser, the curator
of marine mammals at the British Museum of Natural History.

outside of science until the 20th century.
