And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Quite a while ago, I went scuba diving out of La Paz, Mexico. We motored out into the Sea of Cortez and ended up diving on a sea mount. Toward sunset a large school of hammer heads (maybe 25 or 30) began to swim in a big circle above us. It was pretty spectacular. The next day a 40' whale shark also swam above us as we descended into our dive.
"The hammer-like shape of the head may have evolved at least in part to enhance the animal's vision. The positioning of the eyes, mounted on the sides of the shark's distinctive hammer head, allows 360° of vision in the vertical plane, meaning the animals can see above and below them at all times. They also have an increased binocular vision and depth of visual field as a result of the cephalofoil."
Apparently they don't attack humans as often as some of their cousins. Probably because they can't see them too well.

ReplyDeleteThank you for posting this. It is the only time I have seen a hammerhead from this angle, and it is fascinating.

ReplyDeleteThey can get pretty big. I saw some for the first time In Hawaii at sub base Pearl Harbor.
