The São Tomé shrew is a white-toothed shrew about 3.0 in (7.6 cm) long found only on São Tomé Island, São Tomé and Príncipe. It is listed as a critically endangered species due to habitat loss and a restricted range. It was discovered in 1886. The population continues to decrease, making these animals rare. It is found only on São Tomé Island, a small island that is actually a shield volcano that rises out of the Atlantic Ocean.
The São Tomé olive pigeon or maroon pigeon is an endangered species of pigeon which is endemic to the island of São Tomé off the coast of western Africa. It was described by José Vicente Barbosa du Bocage in 1888.
The São Tomé, Príncipe, and Annobón forests, also known as the São Tomé, Príncipe, and Annobón moist lowland forests, is a tropical moist broadleaf forest ecoregion that covers the islands of São Tomé and Príncipe, which form the island nation of São Tomé and Príncipe, as well as the island of Annobón, which is part of Equatorial Guinea.
Hirasiella is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Charopidae. The genus is monotypic, being represented by a single species, Hirasiella clara.
Schistometopum thomense is a species of amphibian in the family Dermophiidae, endemic to São Tomé and Ilhéu das Rolas. It is found in most soils on São Tomé, from tropical moist lowland forests to coastal coconut plantations. It is absent only from the driest northern areas of the island. It is typically around 30 cm (12 in) in length, and is often bright yellow. The size of S. thomense can vary throughout São Tomé, however, and it is the only known caecilian to follow Bergmann's rule, which states that a decreasing temperature due to factors such as increasing altitude will cause an increase in the body size of endothermic vertebrate species. The island of São Tomé is a massive shield volcano, and it therefore has differing altitudes throughout the island, potentially resulting in the size diversity of S. thomense. This species may be referred to as the São Tomé caecilian, as the Agua Ize caecilian, or as the island caecilian, or by the local name of cobra bobo.
Hyperolius thomensis is a species of frog in the family Hyperoliidae. It is endemic to the island of São Tomé in São Tomé and Príncipe. Common names São Tomé reed frog, São Tomé giant reed frog, and Sao Tome giant treefrog have been coined for it. It is the largest Hyperolius species.
The São Tomé spinetail is a species of swift in the family Apodidae. It is endemic to São Tomé and Príncipe. The species was described by Ernst Hartert on 1900.
The São Tomé kingfisher is a bird in the family Alcedinidae. It is endemic to São Tomé, an island off the west coast of Africa in the Gulf of Guinea and was first described by the Italian ornithologist Tommaso Salvadori in 1902 under the binomial name Corythornis thomensis. A molecular phylogenetic study published in 2008 showed that the São Tomé kingfisher is a subspecies of the malachite kingfisher.
The giant sunbird is a species of bird in the family Nectariniidae. It is the only species in the genus Dreptes. It is endemic to the island of São Tomé, where it occurs in the central massif.
The shrew-faced squirrel, also known as the long-nosed squirrel, is a species of rodent in the family Sciuridae. It is monotypic within the genus Rhinosciurus. It is found in forests in Peninsular Malaysia, Singapore, Sumatra and Borneo. This peculiar, terrestrial squirrel mainly feeds on insects and earthworms. It quite closely resembles a Tupaia treeshrew in appearance, but the shrew-faced squirrel can be recognized by its shorter gape, and shorter and more bushy tail.
The São Tomé leaf-nosed bat is a species of bat in the family Hipposideridae. It is endemic to the island of São Tomé, in the Gulf of Guinea off the western coast of Africa. The bat's natural habitats are subtropical or tropical moist lowland forests and caves.
Pyrgina umbilicata is a species of small, tropical, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae.
Rinorea thomensis is a species of plant in the Violaceae family. It is endemic to São Tomé Island.
Pradoxa thomensis is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
The Obô Natural Park of São Tomé is a natural park of São Tomé and Príncipe, covering 195 km2 (75 sq mi) of the island of São Tomé. It was established in 2006, but yet to be assigned an IUCN protected area category. It covers parts of the districts of Caué, Lemba, Lobata and Mé-Zóchi.
Commerson's roundleaf bat, also known as Commerson's leaf-nosed bat, is a species of bat endemic to Madagascar. It is named after French naturalist Philibert Commerson (1727-1773). Bat populations of Africa or São Tomé and Príncipe formerly considered part of this species are now classified separately as M. gigas, M. thomensis or M. vattatus, while one from Madagascar was split off to become M. cryptovalorona. It was formerly placed in the genus Hipposideros, but moved to the resurrected Macronycteris in 2017 on the basis of molecular evidence.
Rio Xufexufe is a river in the island of São Tomé, São Tomé and Príncipe. The river flows southward through the southern part of the Lembá District and empties into the Atlantic Ocean 10 km northwest of Vila Malanza. Its catchment area is 16.5 km2 (6.4 sq mi). The endangered birds São Tomé olive pigeon and São Tomé fiscal have been observed in the catchment of the river.
Thomensis is Latin for "of Thomas" or "of the island of São Tomé". It may refer to several species found on the island and in the surrounding waters:
Trukrhysa is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Chronidae. It is monotypic, being represented by the single species Trukrhysa pachystoma which is endemic to the Caroline Islands, Micronesia.
