The waters around Saleh Bay and the Sumbawa coast are home to a variety of marine life, but the shark species you are most likely to encounter is the whale shark itself. While it is biologically possible that other shark species exist in the broader region, the tour is specifically designed around the whale shark encounter at the bagan fishing platforms, where the ecology attracts plankton-feeders rather than predatory sharks. Guests do not go to areas known for shark populations beyond the whale sharks.
The guides and local boatmen have years of experience in these waters and have never reported encounters with dangerous shark species during the whale shark activities. The focus of the trip is entirely on snorkeling with whale sharks in a controlled, shallow-to-moderate bay environment, not on open-ocean diving or reef exploration where other shark species might be more common. Your time in the water is supervised, and the guides are attentive to the marine life present around you.
If the idea of encountering other sharks makes you nervous, it may help to understand that the vast majority of shark species are harmless to humans and that Indonesia’s marine ecosystems are rich and diverse. The whale shark is the star of this tour, and the team has structured the experience so that you can focus on that encounter without worrying about what else might be swimming nearby. The guides will answer any specific concerns you have before entering the water.
