(regarding definition 2 - I thought if was called a "pod" of whales. Oh well. I suppose there's no rule that there can't be two words with the same meaning.)

So did I, but I've seen 'gam' with regard to whales:

and the American Heritage Dict. of the English language
indicates it also means a congregation of whalers especially
at sea. So they must get together and reminisce about Ahab
after the work is done.
