|.||Whale Biology-humpback whale|
humpbacks grow to an average of about 15 m in length and are
a bit larger than males. The body is stocky and dark gray
in color, the head is broad and flat, and
the dorsal fin is a little more than two-thirds of the way
back on the body and can vary in shape. Distinguishing features
include fleshy knobs or tubercules on the head and lower lip,
and long pectoral fins or flippers one-third the body length.
Humpback whale flukes have an irregular trailing edge and
black and white pigmentation on the nderside. This fluke pattern
is often so distinctive that it can be used to identify individuals.
