That is some clear water. Lucky shark.

  1. Not really. Their vision sucks. It's why they bite a lot of things that aren't food, because they can't tell before then. They get most of their information from the motion sensors along their lateral lines from head to tail.

  2. I wouldn't say it sucks. Sharks actually have pretty good vision (up to around 50-100 ft.) and their low light vision is excellent.

  3. I'd say if you have to live in the water, living in clean water is a lucky thing, even if you are stone blind.

  4. Black Tips are reef sharks. Graceful and interesting, they'll leave you alone if you don't harass them. Even then they'll likely shy away. You really have to want it to get one to come at you. To do so puts you firmly in the stupid jerk category.
    YMMV
