Avoiding diving alone with sharks. Stay in and with a group. You could appear like an easy bait when the shark spots you alone.
But when you are in a group, it is very unlikely that a shark would attack you. Make sure there is an experienced diving instructor with you at all times. Always follow his/her instructions and do not try to be smart or a wiseguy/girl. Keep your eyes on the other member of the groups and don’t stray away from them.
When you are all set to dive, make sure to avoid wearing or carrying anything that is bright in color, like shiny metal or things that glow.
Though sharks are considered color-blind, colors that contrast with the background attracts them. Also, they might mistake the shiny reflections for fish scales. It is always better you wear something dull blue or gray, or any other color that easily blends in with the surrounding water.
Keep the color of your tools or diving equipment sober too.
While diving with sharks, always be calm with your movements and stay relaxed.
No thrashing about or sudden movements. Just maintain a steady pace and try not to make any sort of noise. Some people may panic, get scared and try to move away from the group which could become potentially dangerous.
You must prepare yourself before you step foot into the water. Read and learn as much as you can so you know what to expect. A qualified and licensed instructor will teach you how to behave during the dive.
If not, make it a point to ask him/her about it.
Sometimes, a large shark may appear and suddenly you don’t see it anymore. Be on the lookout because it could reappear again when you least expect it.
If you, or someone else in the group notices a particular shark (especially very large ones) behaving erratically or showing persistent interest in the group, it may be time to end the dive.
Most sharks are crepuscular in their feeding habits (they mainly feed at dawn and dusk). So, that’s when they are actively searching for food. Avoid diving with sharks during dawn or dusk.
At mid-day under bright sunlight is an ideal time for shark diving. Sharks usually keep a distance from groups during this time.
We cannot emphasize this enough: you are going into the sharks’ territory. Respect their space.
Just like humans or any other animal, when a shark sees something approaching it, it may attack out of self-defense. If you swim towards a shark and it moves away from you, leave it alone!
Maintain a safe distance always and whatever you do, don’t pet them on the head or close to their jaw area. This is not a circus monkey or a pet dog. Sharks want their space and it is very important that you give that to them.
Let the shark move on its path undisturbed in any manner. That said, do not try to take pictures with a bright flash.
Don’t free-dive or snorkel around large sea mammals (e.g. seals) where sharks abound. Obviously, you could get caught if sharks arrive for a feeding.
The same goes for spearfishing around sharks. This will definitely draw attention to you, especially as the blood comes out of the fish you’re catching. In the event you begin spearfishing without sharks in the area, but your activities attract them, calmly leave what you were doing and get back to your boat.
