Mesoplodon bowdoini is a poorly known beaked whale described from a New Zealand specimen. It differs from Hector’s beaked whale in skull form and the position and shape of adult male teeth. The body is spindle-shaped with a small dorsal fin and short beak. Adult males are believed to carry flattened teeth near the middle of the lower jaw.
It is known from sparse records in cool Southern Hemisphere waters, including New Zealand. Its normal offshore distribution remains poorly resolved. Its behaviour has scarcely been observed. It is presumed to make deep dives for squid and fish, as related species do.
The New Zealand classification is Data Deficient. There is no reliable viewing location; museum specimens and strandings provide most New Zealand evidence.
