Here is an interesting documentary video I have found about blue whales in Sri Lanka:
This is an interesting video, and boy blue whales are huge. This reminds me of last year when I heard about blue whales being sighted in California. It was very informative too. I've never seen a blue whale myself, though I have seen humpback whales before, especially when I went to Alaska back in the summer of 2010, and even humpbacks are huge as well. I wouldn't mind going on a whale watchign expedition sometime myself.
