Those of us who dive in the Caribbean are used to being in the middle of the food chain.
Back in the 70's my buddy Jim Thompson (now Captain Thompson, 1700 t. all oceans) and I went out about 20 miles to dive for lobster (the tasty ones, not the bite-y ones) and we were anchored and all suited up and ready to go over the side when he pointed.
There was a hammerhead swimming along just under the surface, he must have been 8 feet between the eyes, and nearly as long as our boat.
Jim looked at me, I looked at him, and without a word we stowed our stuff and motored back to the Tiki Bar for some consolation.
I don't think I've ever seen a shark I thought was small.
