Bora Bora is home to many sharks, as a barrier reef encircles the main island. There are also various other wild marine creatures, such as barracudas and stingrays, which you must avoid at all costs. However, be assured that shark attacks in Bora Bora are extremely rare — only two have been documented so far in the previous century. The most recent incident occurred at Bora Bora's Anau lagoon in 2015, when a blacktip shark bit a 9-year-old kid's hand as the youngster was attempting to feed the animal. You must also consider other marine life during your Bora Bora visit, including the sea urchins and the coral itself, both of which may cause painful puncture wounds. Therefore, do not forget to wear protective water shoes whenever you are in the water.  It is also suggested not to pick cone shells since they can be harmful. Besides, be aware of the well-hidden stonefish, which may look like a rock that can release poison when stomped on. If you think you've been stung by a stonefish, get medical help right away and apply heat. Wearing foot protection when visiting snorkeling sites and doing other water activities is the easiest way to avoid this. You will also find a lot of mosquitos in Bora Bora. Remember that mosquitoes spread chikungunya, dengue fever, and other diseases in this area. Hence, use efficient repellent to keep them at bay.
