There are some dangerous shark species present in our waters here (tiger, hammerhead etc.) but the chance of a beach go-er meeting them is very very slim. Divers have more of chance but still very low, you see them occasionally in deep water wreck diving. Rigs also attract with food and human waste being an easy meal. Shallow waters you can get black tips especially around tutrtle nest hatching season (again an easy meal) but they are qite scared of humans.

There is no real need to worry here in Qatar. There are other nasties that will cause you pain that are more likely than a shark bit.

Be safe beachcombers, snorkellers and divers
