Do your own research on Google.com.

Ok so you asked the exact same question on yahoo also, and didn’t get an answer there either.

What exactly is your question? “Which of there more of near Bermuda, blue whales or sperm whales?” or is it just “What kind of whales are in the waters near Bermuda?” The first question might be a little harder, but you would probably have more luck googling instead of asking Fluther or yahoo..

You likely saw a humpback. I would doubt it if you saw either a blue whale or a sperm whale in those waters.
Did what you see look like a baleen whale or a toothed one? They look quite a bit different.
