Humpbacks don't have many predators because of their size.  They are
most vulnerable when they are calves.  See
http://whale.wheelock.edu/archives/ask/0539.html and
http://whale.wheelock.edu/archives/ask/0514.html .

their blubber.

There is al lot of info available about blubber. Try searching for
"blubber"
with the WhaleNet searching engine
(http://whale.wheelock.edu:2834/cgi-bin/search.cgi/x-catalog:/whale.wheeloc
k

good luck.
