Born at a length of a little over 4 metres, humpbacks grow to around 15 metres, with females typically a little larger than males.

The trailing edge of the humpback’s flukes is scalloped and the serrated pattern can assist researchers to identify one individual from another.

Humpbacks usually have some white colouration on the ventral or under sides of their bodies as well, more so in southern hemisphere populations.  The white can sometimes reach high up the flanks as well.

A distinctive feature of humpback whales is the large number of tubercles on the head. These rounded bumps are present from birth and form an irregular line along the centre and margins of the upper jaw, with some more at the tip of the lower jaw.
