(Gray, 1828) - Heaviside's dolphin Heavisides's dolphin is one
of the most poorly known of all cetaceans. The shape of the body
is similar to that in other Cephalorhynchus dolphins: stocky,
with a short blunt snout, and blunt-tipped flippers. The dorsal
fin is more triangular than the rounded fins of the other genus
members, but it is taller than in most porpoises. The body is
predominantly grey, with a dark cape, which starts at the
blowhole, remains extremely narrow in the thoracic region and
then widens to dip low on the side below the dorsal fin. The
area around the eye and much of the face is often darker grey.
There is a white ventral patch that begins just behind the
flippers, and splits into 3 arms behind the umbilicus. The
middle arm encloses the urogenital area and the side arms extend
only to below the midline. There is also a white diamond-shaped
patch between the anterior insertions of the flippers, and
separate white spots in the axillae. Several predominantly white
individuals have been seen. H
