Many things look like a shark including lemon or cobia. We have been fortunate to travel many places and many things. Diving and snorkeling have been a big part of that. There are many easy targets for the shark in the water. A person with fins is close to seven feet long and blowing bubbles. For the most part sharks run. At dusk maybe the shark cannot see all of you so the risk is greater. Same with someone on the surface paddling a surf board.

If all of that is not enough? How many people do you know that have been bitten by dogs or cats? Do you know anyone bitten by s shark. For me I worry about the dogs are cats I do not know and understand the shark wants nothing to do with creatures that fight back. Shark bites are almost always mistaken identity. That means stay out of murky water at dusk.
