Good question! We don't know for sure, but humpbacks are thought to
live to at least 50 years old. The problem is that it's difficult to
age a whale. Humpback whales have these weird waxy plugs in their ears
which grow a little bit every year and put on layers. If you cut up a
dead whale (which isn't easy!) and count the layers in the ear plug, you
can estimate the age of the whale. The problem is that scientists still
arent sure whether the ear plug grows one layer a year, or two (this is
kind of like counting tree rings, but they're not circular in a whale).
The oldest whale is probably the bowhead whale, which lives in the
Arctic. Scientists have recently estimated (using a different
technique) that bowheads live to well over 100 years, maybe a lot more
Good luck with your project!
