Shark Attacks - 7 Answers to Frequently Asked Questions

When do the sharks come out to play? Is there a certain time you should avoid the water?

Most attacks world-wide happen between 8.00 am and 6.00 pm and mostly on weekend during the warmer seasons of the year. This has not so much to do with shark behaviour though but everything with human behaviour since these are the times when most people are spending time in the water.

Sharks will generally hunt at dawn and dusk and at night, but like many predators will feed at any time they come across prey unless they have just eaten and some female sharks like the female Grey Nurse Sharks do not eat at all during mating season.

What do I do if I see a shark while Im swimming?

If you are not sure of the species or intention of the shark you should calmly, quietly and quickly leave the water. However, if it is for example a Leopard Shark, a Port Jackson Shark or a White-tip Reefshark you might consider getting your camera out and take a few shots. In any case treat it with respect and dont try to pick it up, prod it or provoke it in any way.

How can I tell which sharks are dangerous, and which are harmless?

Great White Shark - photographed by underwater australasia member Daniel NorwoodThere are several species that can inflict injury when they are provoked or harassed, but only 4 species are considered to be truly dangerous: Tiger Shark, Bull Shark, Great White Shark and Oceanic White-tip

This has to do with their world-wide distribution as these species can be found in many places, size and choice of natural prey. And lets be realistic no-one is reporting the fact they were nibbled on by a Small-eye Pygmy Shark (maximum size recorded 22 cm) and it would be unlikely too since they live at a depth of 2000 200 m.

Even so there are times that swimming with even those sharks can be safe and many people have encountered those sharks unexpectedly and were fine. However, it is recommended to leave the water.

There are many theories why sharks attack or injure people and no one really knows. A few theories include mistaken identity with a prey animal, being curious and using their tasting organs located in their mouth to check or they attack when they feeling threatened or cornered.

Harmless sharks would include species such as the Port Jackson Shark, Leopard Shark, Blind Sharks and most smaller shark species. However, as with all animal wild ones in particular - sharks that are cornered, harassed or threatened can respond unpredictably.

What do I do if I get attacked by a shark? (eg. have heard you kick it between the eyes is this true?)

Grey Nurse Shark - photographed by underwater australasia member Peter HitchinsVarious strategies can be found on how to fight a shark in books and on the web. Logic tells us that indeed it would be sensible to go for areas that are most sensitive such as the snout where the ampullae of Lorenzini are located, the eyes or the gills. While you are at it pull its claspers if it is a male. Practically, would you really be able to reach those spots whilst you are being attacked?

In any case it is not recommended to play dead but instead fight for your life and find anything hard or sharp to hit or stab the shark wherever your can. If a shark bumps you and swims off you should quickly, but calmly (?!) exit the water trying to keep facing the shark. When SCUBA diving and you have enough air find a spot with your back against a solid surface or back-to-back with your buddy and try to get back to shore or the boat. If you are being injured or hurt seek immediate medical assistance even if it does not seem serious at the time.

Is it true that if I wear a black wetsuit, sharks will think Im a seal and are more likely to attack me?

A lot of wetsuits people wear tend to be a darker colour and looking up from down below against the light anything on the surface looks dark anyway. Shark experts also believe that sharks make up their mind on where to go long before they have visual contact.

As mentioned above, it is not quite clear why people do get attacked and since Great White Sharks for example have an exceptional visual system this explanation is quite unlikely. However, when you go surfing in an area that is a hunting ground for sharks and move like an injured seals, waves crashing all around you, etc a shark might get confused.
