such as beautiful flamingo tongue snails (Cyphoma gibbosum) live here. Coral Reefs Bonaire is surrounded by fringing reefs. These consist of about 60 different coral species, including brain corals, elkhorn corals, fire corals and gorgonians. The reefs offer a variety of marine life. Some of the most common fish species are surgeonfish, parrotfish, reefperch and wrasses. In addition, countless invertebrates such as shrimp, crayfish and squid live here. Bonaire's coral reefs were seriously damaged in 1999 by hurricane Lenny. Furthermore, they are threatened by the effects of pollutants and the warming of the sea. Lac bay In the lagoon of Lac Bay is the only significant concentration of mangroves on Bonaire. Here grow red, black and white mangrove as well as button mangrove. The 700-acre lagoon has been a Ramsar site since the 1980s, offering habitat to green sea turtle and other endangered species, such as queen conch (Strombus gigas). Tourism Already in 1939, the famous diving pioneer Hans Hass visited Bonaire and reported in his books on the rich underwater world. Bonaire National Marine Park known as one of the hotspots for divers in the Caribbean and as one of the world's best places for snorkeling. For example, Forbes magazine ranked BNMP among the top 10 must-dive destinations in the world in 2017. In the Bonaire Marine Park, Dixon et al. (1994) found that most divers seldom venture further than 300 m in one direction and that there was a decreasing physical impact on reef communities with increasing distance from a mooring buoy. Analyzing coral cover, they estimate that the diver carrying capacity threshold for the Bonaire Marine Park is between 4000 and 6000 dives per site per year.J.A. Dixon et al. (1994) Ecology and microeconomics as joint products: the Bonaire Marine Park in the Caribbean. In: C. Perrings, et al. (eds) Biodiversity conservation: problems and politics. Kluwer Academic Press, Dordrecht In addition, various activities such as kitesurfing, sailing and windsurfing are offered in the area of the Bonaire National Marine Park. Unique to the Bonaire National Marine Park is that it runs entirely on its own income (without subsidies). The income comes from an entrance fee for divers. Other users, such as swimmers, surfers, kite boarders, kayakers and water sports enthusiasts, pay a lower entrance fee. This also gives access to the Washington Slagbaai National Park. In addition to nature protection, the BNMP provides information about responsible diving
