Not much
is known about these dolphins other than what they look
like. Heaviside's dolphins are small, compact, and robust
dolphins. They have a prominent, triangular dorsal fin
with a broad base, and small flippers with blunt tips.
The front half of their body is a light grey color,
which then sweeps into a dark bluish black in their
tail half. These dolphins have brilliant white undersides
which curve up into finger shaped lobes which point
towards their tails. They also have brilliant white
armpits just above their flippers! Their heads are unusually
cone-shaped, and they have flattened foreheads with
no distinct beak.
