What do sharks look like?
Sharks come is a wide variety of shapes and sizes, but there are some things they all have in common. The skeleton of a shark is very different from that of other fish. It is made from rubbery cartilage, a tissue lighter and more flexible than bone. Like other fish, sharks breathe by extracting oxygen from seawater as it passes over their gills which are in a row behind its head. Their skin is tough and scratchy, covered in tiny toothlike scales. All sharks have multiple rows of teeth along the edges of their upper and lower jaws which are constantly replaced throughout the sharks life. Some sharks can lose 30,000 teeth in a lifetime.

- sound a siren or ring a bell,
- put up the red and white flag and
- tell you to leave the water immediately.
Always follow the Lifesavers instructions quickly and always look out for and obey their warnings.
- Don’t swim after dusk, at night or before dawn when sharks are most active.
- Never swim alone.
- Never swim while bleeding or with your pets. Sharks have an excellent sense of smell and will come from far and wide to investigate these smells.
- Don’t swim in murky waters, estuary mouths, canals, near schools of fish or where fish are being cleaned.
- Do not swim near or interfere with Shark Control Program equipment.
Most patrolled beaches along the Queensland coast have nets suspended in the sea just beyond the surf line. Their job is to capture very large and possibly dangerous sharks that try to reach beaches. You might see a line of white marker boys beyond the waves that mark the nets — stay away from them.
What to do in the event of a shark attack
- Get the person out of the water when it is safe to do so.
- Call 000.
- Apply pressure to stop the bleeding and provide CPR if necessary.
