Beaked Whale Identification Guide
Tooth position
A single pair of teeth are positioned at the top of the anterior edge of the jaw arch. The tooth root is squared at the base.

Tooth exposure
Erupted teeth in adult males are covered by gum tissue with only the tip of tooth exposed. Teeth do not erupt in females or juveniles.

Tooth shape
The teeth resemble the leaf of a ginkgo tree. The denticle is centrally positioned between anterior and posterior most points of the tooth. Anterior and posterior tooth margins are concave and nearly symmetric.
