* Humpback whales are baleen
whales known as rorquals.
* They are found in all of the world's oceans, and they can be seen
from the mainland in many places in the world.
* They are the beautiful black-and-white
coloured whales that often breach. Their back is
black and their belly is often white.

* While most baleen whales cruise-feed by swimming through krill
swarms, humpback whales rise through shoals of fish from
* They do "bubble-netting":
they work together in a group and blow
a ring of bubbles around swarms of small fish. The fish, getting
"trapped in bubble nets", swim to the surface. The humpbacks follow
and scoop the fish as they go.
* Like many other large baleen
whales, Humpbacks migrate
feeding grounds near the poles (during the summer), and warm breeding
grounds closer to the equator (during the winter).
* It is believed that they cannot go beyond the equator, so the southern and northern populations
may never meet, because the seasons are the opposite in
hemispheres, so when the northern whales head south towards the
equator during the winter, the southern whales leave the equator for
cool feeding grounds towards the poles, because in the Southern
Hemisphere it's summer.
