Fraser's dolphin (Lagenodelphis hosei) is a cetacean in the family Delphinidae found in deep waters in the Pacific Ocean and to a lesser extent in the Indian and Atlantic Oceans. 
It is a very rare visitor to New Zealand’ water.

Fraser's dolphins grow up to 2.75 m in length and 200 kg in weight, They have a stocky build, a small fin in relation to the size of the body, conspicuously small flippers. The dorsal fin located in the middle of the dorsum, it is small, triangular and slightly curved. The body’s upper side is a grey-blue to grey-brown. A dirty cream coloured line runs along the flanks from the beak, above the eye, to the anus. There is a dark stripe under this line. The belly and throat are usually white, sometimes tinged pink. The lack of a prominent beak is a distinguishing characteristic of this dolphin.
Their diet is composed of mesopelagic fish, cuttlefish, squid and shrimp
