beaked whales appear to be one of the most abundant
of the beaked whale family. Their foreheads slope gently
to a slight beak which becomes less obvious with age.
They have two teeth which are just visible when the
mouth is closed. Their colour varies from black to brown
with white or cream coloured blotches and circular scars
on the underside and sides. Older males have extensive
white areas from the beak to the top centre of the body.
They have long, robust bodies with dorsal fins which
vary from triangular to sickle-shaped. Their flukes
are broad, being up to one quarter of their body length
with no middle notch.
