The bull shark, also known as the Zambezi shark in Africa and Lake Nicaragua shark in Nicaragua, is a species of requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers. It is known for its aggressive nature, and presence mainly in warm, shallow brackish and freshwater systems including estuaries and (usually) lower reaches of rivers. This aggressive nature is a reason for its population being listed as vulnerable on the IUCN Red List. Shark-culling occurs near beaches to protect beachgoers, which is one of the causes of bull shark populations continuing to decrease.
The Socotra sparrow is a passerine bird endemic to the islands of Socotra, Samhah, and Darsah in the Indian Ocean, off the Horn of Africa. The taxonomy of this species and its relatives is complex, with some authorities, including BirdLife International, recognising this species and the very similar Abd al-Kuri sparrow, as well as several from mainland Africa, as separate, and others lumping all these species and the probably unrelated Iago sparrow.
The Socotra cormorant is a threatened species of cormorant that is endemic to the Persian Gulf and the south-east coast of the Arabian Peninsula. It is also sometimes known as the Socotran cormorant or, more rarely, as the Socotra shag. Individuals occasionally migrate as far west as the Red Sea coast. Despite its name, it was only confirmed in 2005 that it breeds on the Socotra islands in the Indian Ocean.
Hypericum balfourii is a species of flowering plant in the family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It grows in mountain shrubland dominated by Cephalocroton. It is usually found on granite terrain above 600 meters in elevation.
Hypericum fieriense is a species of flowering plant in the St. John's wort family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It grows in mountain shrubland dominated by Cephalocroton, where it can be found with the endemic tree Dracaena cinnabari. It is rarer than other local shrubby Hypericum species. It can be distinguished from them by its pubescent herbage.
Hypericum scopulorum is a species of flowering plant in the family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It is a common plant in shrubland habitat, and it is a dominant species in some areas along with Cephalocroton and another local endemic, Libinhania rosulata.
Hypericum tortuosum is a species of flowering plant in the genus Hypericum. It is found only in Socotra, Yemen, where it is endemic. The species is an apomorphic relative of the other Socotran species in Hypericum sect. Triadenioides and is most closely related to Hypericum scopulorum. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Leucas flagellifera is a species of flowering plant in the family Lamiaceae. It is endemic to Socotra. Its natural habitat is subtropical or tropical dry shrubland. The scientific name has been misspelt as Leucas flagellifolia.
Leucas kishenensis is a species of flowering plant in the family Lamiaceae. It is a shrub endemic to the Hajhir Mountains of Socotra island in Yemen, where it grows in open semi-deciduous shrubland on granite from 650 to 1,000 metres elevation.
Leucas penduliflora is a species of flowering plant in the family Lamiaceae. It is found only in Yemen. Its natural habitat is subtropical or tropical dry shrubland.
Leucas samhaensis is a species of flowering plant in the family Lamiaceae. It is endemic to the island of Samhah in Yemen's Socotra Archipelago. Its natural habitat is subtropical or tropical dry shrubland.
Leucas spiculifera is a species of flowering plant in the family Lamiaceae. It is found only in Yemen. Its natural habitat is rocky areas.
Leucas virgata is a species of flowering plant in the family Lamiaceae. It is endemic to the island of Socotra in Yemen. It is common and widespread in open shrubland and drought-deciduous woodland on the island's limestone plateaus from 100 to 700 metres elevation.
The Socotra starling is a species of starling in the family Sturnidae. It is endemic to Socotra island, which is off the southeast coast of Yemen.
Euphorbia arbuscula is a species of plant in the spurge family (Euphorbiaceae). It is endemic to the archipelago of Socotra in Yemen. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Socotrella is a monotypic genus of plant in family Apocynaceae. It contains the single species Socotrella dolichocnema, which is endemic to Socotra.
The Socotra golden-winged grosbeak or Socotra grosbeak is a finch endemic to Socotra, an island in the Indian Ocean off the coast of Yemen. R. socotranus is by some authorities held to be the only species of the then-monotypic genus Rhynchostruthus, including all other golden-winged grosbeaks therein as subspecies. But in recent times the three populations are usually considered a distinct species, with R. socotranus being limited to the Socotra population, the Arabian golden-winged grosbeak becoming R. percivali, and the Somali golden-winged grosbeak R. louisae.
The Abd al-Kuri sparrow is a passerine bird endemic to the small island of Abd al Kuri in the Socotra archipelago of the Indian Ocean, off the Horn of Africa. Though this species was originally described as a distinct species, it was subsequently considered conspecific with the Socotra sparrow. A study by Guy Kirwan showed significant differences from the Socotra sparrow, and that the two sparrows might even have different origins. On the evidence that it is morphologically distinct, BirdLife International recognised it as a species, and it was listed in the IOC World Bird List from December 2009. It has a very restricted distribution, and a population of under 1,000 individuals, so despite not having any known threats it is considered a Vulnerable species on the IUCN Red List.
The Socotran pipistrelle or Lanza's pipistrelle is an endangered species of vesper bat in the family Vespertilionidae. It is endemic to Socotra Island in Yemen, and is the only mammal thought to be endemic to the island.
