I think (in fact, I know) it's spelled Mako. And this is going to sound funny, but that is truly and totally my favorite marine animal. The Mako shark is just awesome-looking, and fast as hell. There's debate on whether it, or the sailfish is the fastest living thing in the ocean.
That reminds me, though, the first time I went fishing in the ocean (around this time last year) my first catch was a 3-foot dogfish (which is actually a shark).
