Common Tern

Common Tern

Terns are smaller and more graceful in flight than gulls. The Common Tern Sterna hirundo (right) grows to 14", wingspan 31". Their forked tails make it easy to differentiate terns from Laughing Gulls, which also have black heads.

Terns are found in the same habitats as gulls, that is to say, just about anywhere near water. Their call is a common sound along waterfronts everywhere.

tiger shark teeth

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.
