If you are going to worry about a shark, let it be this one. Tiger Sharks are big, bold and inquisitive, and frequently come close inshore. They are also remarkably undiscriminating in their eating habits, which makes them even more likely to attack a swimmer, or anything for that matter.

Tiger sharks have the ability to evert ( turn inside-out ) their stomachs, much like starfish. This allows them to 'test' all sorts of food items that would otherwise choke them, like license plates and surfboards.

Note that this shark and the one above are both swimming over coral reefs, nowhere near New Jersey!

A Tiger shark swims in the surf off Australia. Habits like this are what make this shark so dangerous. Fortunately for us, Australia is very far from New Jersey.

copper penny

Copper, brass, and bronze are all relatively immune to saltwater corrosion. Brass artifacts of all sorts are easily cleaned up into shiny souvenirs for those who value them. Bright green copper sheets and tubes add color to many wrecks, while bronze is the material of choice for the most coveted of all diver's artifacts - a ship's bell.

Copper and some of its alloys have been used by humanity since the Bronze Age. One of the first metals known to humans, free copper was probably mined in the Tigris-Euphrates valley as long ago as the 5th century BC. Cyprus, from which the metal's name originally comes, was the primary source of copper in the ancient world.
