Ernst Ahl
Christoph Gustav Ernst Ahl (1 September 1898 – 14 February 1945) was a German Zoology, zoologist, born in Berlin. He was the director of the department of ichthyology and herpetology in the Museum für Naturkunde. He was also the editor in chief of the review ''Das Aquarium'' from 1927 to 1934. During World War II, Ahl fought in the ranks of the Wehrmacht - in Poland, North Africa and later Yugoslavia. He was executed while in refuge in Yugoslavia, after the partisans found out he was a German. He performed one of the first studies on Pogona, bearded dragons determining what genus they belong to. Ahl is commemorated in the scientific names of two species of lizards: ''Anolis ahli'' and ''Emoia ahli''.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Ahl", p. 3). The latter is a synonym of ''Emoia battersbyi''.

Caecilian
Caecilians (; ) are a group of limbless, vermiform or serpentine amphibians. They mostly live hidden in the ground and in stream substrates, making them the least familiar order of amphibians. Caecilians are mostly distributed in the tropics of South and Central America, Africa, and southern Asia. Their diet consists of small subterranean creatures such as earthworms. All modern caecilians and their closest fossil relatives are grouped as a clade, Apoda , within the larger group Gymnophiona , which also includes more primitive extinct caecilian-like amphibians. The name derives from the Greek words γυμνος (''gymnos'', naked) and οφις (''ophis'', snake), as the caecilians were originally thought to be related to snakes. The body is cylindrical dark brown or bluish black in colour. The skin is slimy and bears grooves or ringlike markings. Description Caecilians completely lack limbs, making the smaller species resemble worms, while the larger species, with lengths up ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Indotyphlidae
The Grandisoniidae are a family of common caecilians found in Africa, Seychelles and India. Like other caecilians, they superficially resemble worms or snakes. The family was formerly known as Indotyphlidae. Taxonomy The genera in this family were originally placed in family Caeciliidae. In 2011, the genera '' Gegeneophis'', '' Grandisonia'', '' Hypogeophis'', '' Idiocranium'', ''Indotyphlus'', '' Praslinia'' and '' Sylvacaecilia'' were segregated into family Indotyphlidae, named after the tribe Indotyphlini, which was used by Lescure et al (1986) for the Indian genera, ''Gegeneophis'' and ''Indotyphlus''. However, it was later pointed out that the name Grandisoniidae is the appropriate family-group name because, according to rules of the Nomenclatural Code, a name published at higher rank, Grandisoniinae, has precedence over a name of lower rank published in the same work, Indotyphlini.Dubois, Ohler, and Pyron, 2021, Megataxa, 5: 1–738 Genera and species *Genus '' Geg ...

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahé, Seychelles
Mahé is the largest island of Seychelles, with an area of , lying in the northeast of the Seychellean nation in the Somali Sea part of the Indian Ocean. The population of Mahé was 77,000, as of the 2010 census. It contains the capital city of Victoria and accommodates 86% of the country's total population. The island was named after Bertrand-François Mahé de La Bourdonnais, a French governor of Isle de France (modern-day Mauritius). History Mahé was first visited by the British in 1609 and not visited by Europeans again until Lazare Picault's expedition of 1742. The French navy frégate '' Le Cerf'' (English: The Deer) arrived at Port Victoria on 1 November 1756. On board was Corneille Nicholas Morphey, leader of the French expedition, which claimed the island for the King of France by laying a Stone of Possession on Mahé, Seychelles’ oldest monument, now on display in the National Museum, Victoria. In August 1801 a Royal Navy frigate HMS ''Sibylle'' captured t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Praslin
Praslin () is the second largest island (38.5 km2) of the Inner Seychelles, lying northeast of Mahé in the Somali Sea. Praslin has a population of around 7,533 people and comprises two administrative districts: Baie Sainte Anne and Grand' Anse. The main settlements are the Baie Ste Anne, Anse Volbert and Grand' Anse. It was named ''Isle de Palmes'' by explorer Lazare Picault in 1744. During that time it was used as a hideaway by pirates and Arab merchants. In 1768 it was renamed ''Praslin'' in honor of French diplomat César Gabriel de Choiseul, duc de Praslin. Praslin is known as a tourist destination with several hotels and resorts, as well as a number of beaches such as Anse Lazio and Anse Georgette. It has substantial tracts of tropical forests with birds such as the endemic Seychelles bulbul and the Seychelles black parrot. The Vallée de Mai Nature Preserve, established in 1979, is known for the unique coco de mer and vanilla orchids. It has been reported ...

La Digue
La Digue is the third most populated island of the Seychelles, and fourth largest by land area, lying east of Praslin and west of Felicite Island. In size, it is the fourth-largest granitic island of Seychelles after Mahé, Praslin and Silhouette Island. It has a population of 2,800 people. Most of the inhabitants live in the west coast villages of La Passe (linked by ferry to Praslin and Mahé) and Anse Réunion. There is no airport on La Digue, so to get there from a foreign country, one must fly to Victoria and continue by ferry, usually via Praslin. It has an area of 10.08 km2, which makes it relatively easy to travel around by bike or on foot. La Digue was named after a ship in the fleet of French explorer Marc-Joseph Marion du Fresne, who visited the Seychelles in 1768. History According to modern historians, La Digue was first sighted by the French navigator Lazare Picault in 1742, but it was not named until 1768. The first people settled on the island in 1789, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silhouette Island
Silhouette Island lies northwest of Mahé in the Seychelles. It is the third largest granitic island in the Seychelles. It has an area of 20.1 km2 and has a population of 200, mostly workers on the island. The main settlement is La Passe, where ''Hilton Hotel'' is located. The name Silhouette was given after Étienne de Silhouette (1709-1767), the French minister of finances under Louis XV. Geography The island is mountainous with five peaks over in elevation; Mont Dauban , Mont-Pot-a-Eau , Gratte Fesse , Mont Corgat and Mont Cocos Marrons . As such, it has some of the most dramatic scenery of the islands. Though superficially similar to neighbouring islands, much of Silhouette is made up of younger syenite dated from 63 million years ago. Between Point Ramasse Tout and Point Zeng Zeng lies the only surface volcanic ash in Seychelles. Demographics The population of 200 lives in 3 villages, Grand Barbe (no longer inhabited), which is on the west coast, Anse Mondon (no ...
