Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

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] |
Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinobatos
''Rhinobatos'' is a genus of fish in the Rhinobatidae family. Although previously used to encompass all guitarfishes, it was found to be polyphyletic, and recent authorities have transferred many species included in the genus to ''Acroteriobatus'', ''Glaucostegus'', and ''Pseudobatos''. Species The 15 currently recognized species in this genus are: * ''Rhinobatos albomaculatus'' Norman, 1930 (White-spotted guitarfish) * ''Rhinobatos annandalei'' Norman, 1926 (Annandale's guitarfish) * ''Rhinobatos borneensis'' Last, Séret & Naylor, 2016 (Borneo guitarfish) * ''Rhinobatos holcorhynchus'' Norman, 1922 (Slender guitarfish) * ''Rhinobatos hynnicephalus'' J. Richardson, 1846 (Ringstreaked guitarfish) * ''Rhinobatos irvinei'' Norman, 1931 (Spineback guitarfish) * ''Rhinobatos jimbaranensis'' Last, W. T. White & Fahmi, 2006 (Jimbaran shovelnose ray) * ''Rhinobatos lionotus'' Norman, 1926 (Smoothback guitarfish) * ''Rhinobatos nudidorsalis'' Last, Compagno & Nakaya, 2004 (Barebac ...

Fauna Of Seychelles
The Wildlife of Seychelles comprises the flora and fauna of the Seychelles islands off the eastern coast of Africa in the western Indian Ocean. Human history and fauna In common with many fragile island ecosystems, the early human history of Seychelles saw the loss of biodiversity including the disappearance of most of the giant tortoises from the granitic islands, felling of coastal and mid-level forests and extinction of species such as the Marianne white-eye, Seychelles parakeet, Seychelles black terrapin, and the saltwater crocodile. However, extinctions were far fewer than on other islands such as Mauritius or Hawaii, partly due to a shorter period of human occupation (since 1770). The Seychelles today is known for success stories in protecting its flora and fauna. Arguably the first scientific study of Seychelles was that of the Marion Dufresne expedition in 1768, two years prior to settlement. Dufresne instructed Duchemin, captain of the vessel La Digue, to ...''especi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Mauritius
The wildlife of Mauritius consists of its flora and fauna. Mauritius is located in the Indian Ocean to the east of Madagascar. Due to its isolation, it has a relatively low diversity of wildlife; however, a high proportion of these are endemic species occurring nowhere else in the world. Many of these are now threatened with extinction because of human activities including habitat destruction and the introduction of non-native species. Some have already become extinct, most famously the dodo which disappeared in the 17th century. Fauna Mammals Due to its isolated geographic location, remote from large land masses, Mauritius originally had no terrestrial mammals. The only mammals that made their way to the island are bats and marine mammals. Of the two fruit bats, only one remains – the Mauritian flying fox. Two insectivorous microbats also remain. A number of mammals have been introduced either accidentally or intentionally, including rats, mice, tenrecs, mongooses, rusa de ...
