Anyone seen any sharks attack or be aggressive in South Walton 30A? A friend told me about 15 years ago he was in a kayak and a shark (probably bull shark which are known to be about the only sometimes aggressive sharks around here) charges and bit at his boat. Scared the crap out of him so much he never went back out.
This article got me thinking about it.

- This year is no different than any other in terms of shark bites, the world is on track to have a “normal” number of shark bites.
- 60% of shark bites take place in areas with low visibility. Sharks don't target humans, so nearly every bite is due to mistaken identity. Like us, sharks can't see very well in murky water.
- There are more than 530 different species of sharks. Some lay eggs. Others give birth to live young. There are even some shark species that nourish their young by placenta, like humans do.
- Some species of sharks have the capacity for trans-oceanic travel but return to the same locations each time they give birth. In this sense they are like turtles.
- Sharks have existed for 400 million years, yet they have unusually low mutation rates relative to other vertebrate animals.
