Axoclinus Multicinctus
''Axoclinus multicinctus'', known commonly as the multibarred triplefin, is a species of triplefin blenny. This species is endemic to the eastern Pacificwhere it is known to occur only from the Revillagigedo Islands of Socorro and San Benedicto San Benedicto, formerly Isla de los Innocentes, is an uninhabited island, and third largest island of the Revillagigedo Islands, located in the Pacific Ocean.

Triplefin
Threefin or triplefin blennies are blenniiforms, small percomorph marine fish of the family Tripterygiidae. Found in tropical and temperate waters of the Atlantic, Pacific and Indian Oceans, the family contains about 150 species in 30 genera. The family name derives from the Greek ''tripteros'' meaning "with three wings". With an elongated, typical blenny form, threefin blennies differ from their relatives by having a dorsal fin separated into three parts (hence the name); the first two are spinous. The small, slender pelvic fins are located underneath the throat and possess a single spine; the large anal fin may have one or two spines. The pectoral fins are greatly enlarged, and the tail fin is rounded. The New Zealand topknot, ''Notoclinus fenestratus'', is the largest species at 20 cm in total length; most other species do not exceed 6 cm. Many threefin blennies are brightly coloured, often for reasons of camouflage; these species are popular in the aquarium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revillagigedo Islands
The Revillagigedo Islands ( es, Islas Revillagigedo, ) or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately from Socorro Island south and southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and west of Manzanillo. Historically linked to the Mexican state of Colima, to which they were granted in 1861 to establish a penal colony, the islands are under Mexican federal property and jurisdiction. In July 2016, the Revillagigedo Archipelago was inscribed as a UNESCO World Heritage Site, and in November 2017 they were declared to be a marine reserve and a national park of Mexico. Some of the volcanoes are active, with the last eruption of Volcán Bárcena in 1953, and Socorro in 1993. Travelling to the islands from their nearest land point takes approximately 26 to 30 hours, as they are typically reached by sea; a small military airstrip exists on Socorro. Geogr ...

Socorro Island
Socorro Island ( es, Isla Socorro) is a small volcanic island in the Revillagigedo Islands, a Mexican possession lying off the country's western coast. The size is 16.5 by 11.5 km (10.25 by 7.15 miles), with an area of . It is the largest of the four islands of the Revillagigedo Archipelago. The last eruption was in 1993. Geology The island rises abruptly from the sea to in elevation at its summit. Socorro Island is the emerged summit of a massive, predominately submarine shield volcano. The island is part of the northern Mathematicians Ridge, a mid-ocean ridge that became largely inactive 3.5 million years ago when activity moved to the East Pacific Rise. All four islands along with the many seamounts on the ridge are post-abandonment alkaline volcanoes. Socorro Island is unusual in that it is the only dominantly silicic peralkaline volcanic island in the Pacific Ocean. It most recently erupted in late Januaryearly February, 1993, which was a submarine flank erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Benedicto
San Benedicto, formerly Isla de los Innocentes, is an uninhabited island, and third largest island of the Revillagigedo Islands, located in the Pacific Ocean. It is 4.8 km by 2.4 km in size, with an area 10 km². It is of volcano, volcanic origin. It has two prominent peaks. The tallest peak, Bárcena, rises to a height of 332 metres (1,089 feet) near the southern part of the island. It forms a typical volcanic crater. It is located between the remains of two older craters, Herrera in the middle of the island and the Montículo Cinerítico ("Ash Heap") in the southwest. There is no permanent source of freshwater. History The first recorded sighting of San Benedicto was by the Spanish expedition of Hernando de Grijalva on 28 December 1533 that charted it as ''Isla de los Inocentes'' due to this day being the festivity of the Massacre of the Innocents, Holy Innocents. In November 1542, it was sighted again by the expedition of Ruy López de Villalobos that i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axoclinus
''Axoclinus'' is a genus of Threefin blenny, triplefins in the family (biology), family Tripterygiidae. This genus has six described species. It is restricted to the eastern tropical Pacific. The genus is characterised by having ctenoid scales, a lateral line which shows pored scales towards the head and notched scales towards the tail, the pelvic fins have two separated rays and the anal fin also has two spines and the possession of vomerine teeth but no palatine teeth.
