Humpback whales are a baleen whale and are renowned for their spectacular behaviour of leaping out of the water, rolling in the air with
their huge pectoral fins outstretched like wings, and crash noisily back into the water.
Fifteen years ago, in Baja, I watched fishermen unload
huge (bigger than baths) tubs of massive fins (mostly dorsal and
pectoral fins), on a more recent trip, the fins were not much bigger than my palm in a couple of buckets.
