restricted to Sulawesi, especially the Malili Lake system, consisting of Matano and Towuti, and the small Lontoa (Wawantoa), Mahalona and Masapi. Another unusual endemic is Lagusia micracanthus from rivers in South Sulawesi, which is the sole member of its genus and among the smallest grunters. The gudgeon Bostrychus microphthalmus from the Maros Karst is the only described species of cave-adapted fish from Sulawesi, but an apparently undescribed species from the same region and genus also exists. Freshwater crustaceans and snails Many species of Caridina freshwater shrimp and parathelphusid freshwater crabs (Migmathelphusa, Nautilothelphusa, Parathelphusa, Sundathelphusa and Syntripsa) are endemic to Sulawesi. Several of these species have become very popular in the aquarium hobby, and since most are restricted to a single lake system, they are potentially vulnerable to habitat loss and overexploitation. There are also several endemic cave-adapted shrimp and crabs, especially in the Maros Karst. This includes Cancrocaeca xenomorpha, which has been called the "most highly cave-adapted species of crab known in the world". The genus Tylomelania of freshwater snails is also endemic to Sulawesi, with the majority of the species restricted to Lake Poso and the Malili Lake system. Insects The Trigonopterus selayarensis is a flightless weevil endemic to Sulawesi. Miscellaneous The Indonesian coelacanth and the mimic octopus are present in the waters off Sulawesi's coast. Conservation Sulawesi island was recently the subject of an Ecoregional Conservation Assessment, coordinated by The Nature Conservancy. Detailed reports about the vegetation of the island are available. The assessment produced a detailed and annotated list of 'conservation portfolio' sites. This information was widely distributed to local government agencies and nongovernmental organizations. Detailed conservation priorities have also been outlined in a recent publication. The lowland forests on the island have mostly been removed. Because of the relative geological youth of the island and its dramatic and sharp topography, the lowland areas are naturally limited in their extent. The past decade has seen dramatic conversion of this rare and endangered habitat. The island also possesses one of the largest outcrops of serpentine soil in the world, which support an unusual and large community of specialized plant species. Overall, the flora and fauna of this unique center of global biodiversity is very poorly documented and understood and remains critically threatened. The islands of Pepaya, Mas, and Raja islands, located in Sumalata Village – North Gorontalo Regency (about 30 km from Saronde Island), have been named a
