Dendrochirus Zebra
''Dendrochirus zebra'', known commonly as the zebra turkeyfish or zebra lionfish among other vernacular names, is a species of marine fish in the family Scorpaenidae. The zebra turkeyfish is widespread throughout the tropical waters of the Indo-West Pacific, including the Red Sea. Description The zebra turkeyfish is a scorpaenid fish with vertical stripes in orange, white, and black on its body, and large, banded, fan-like pectoral fins that flare out on either side as the fish lies on the seabed. The front dorsal fin is made up of 13 tall, quill-like spines and the second dorsal fin has 10 or 11 soft rays. The anal fin has three spines and about 10 soft rays. The second dorsal fin, the anal fin, and the rounded caudal fin are transversely banded in black and white. This fish grows to a maximum length around . Distribution and habitat The zebra turkeyfish is native to the Indo-Pacific region from the Red Sea to Indonesia and eastern Australia. It is found in inshore waters down ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Scorpaenidae
The Scorpaenidae (also known as scorpionfish) are a family of mostly marine fish that includes many of the world's most venomous species. As their name suggests, scorpionfish have a type of "sting" in the form of sharp spines coated with venomous mucus. The family is a large one, with hundreds of members. They are widespread in tropical and temperate seas but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus '' Scorpaenichthys'', which belong to a separate, though related, family, Cottidae. Taxonomy Scorpaenidae was described as a family in 1826 by the French naturalist Antoine Risso. The family is included in the suborder Scorpaenoidei of the order Scorpaeniformes in the 5th Edition of ''Fishes of the World'' but other authorities place it in the Perciformes either in the suborder Scorpaenoidei or the superfamily Scorpaenoidea. The subfamilies of this family are treated as valid families by some authorities. Subfamilies and trib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-West Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in a ...

Red Sea
The Red Sea ( ar, البحر الأحمر - بحر القلزم, translit=Modern: al-Baḥr al-ʾAḥmar, Medieval: Baḥr al-Qulzum; or ; Coptic: ⲫⲓⲟⲙ ⲛ̀ϩⲁϩ ''Phiom Enhah'' or ⲫⲓⲟⲙ ⲛ̀ϣⲁⲣⲓ ''Phiom ǹšari''; Tigrinya: ቀይሕ ባሕሪ ''Qeyih Bahri''; ) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab el Mandeb strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly 438,000 km2 (169,100 mi2), is about 2250 km (1398 mi) long, and — at its widest point — 355 km (220.6 mi) wide. It has an average depth of 490 m (1,608 ft), and in the central ''Suakin Trough'' it reaches its maximum depth of . The Red Sea also has exten ...

Red Lionfish
The red lionfish (''Pterois volitans'') is a venomous coral reef fish in the family Scorpaenidae, order Scorpaeniformes. It is mainly native to the Indo-Pacific region, but has become an invasive species in the Caribbean Sea, as well as along the East Coast of the United States and East Mediterranean and also found in Brazil at Fernando de Noronha. ''P. volitans'' and a similar relative, '' Pterois miles'', have both been deemed invasive species. Red lionfish are clad in white stripes alternated with red, maroon or brown stripes. Adults in this species can grow as large as 47 cm (18.5 in) in length, making it one of the largest species of lionfish in the ocean, while juveniles are typically shorter than .National Oceanic and Atmospheric Administration, National Centers for Coastal Ocean Science "Have You Seen Me?"

Spotfin Lionfish
''Pterois antennata'', the spotfin lionfish, banded lionfish, broadbarred lionfish, broadbarred firefish, raggedfinned firefish, raggedfinned scorpionfish or roughscaled lionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes and lionfishes. It is found in the tropical Indian and Western Pacific Oceans. Taxonomy ''Pterois antennata'' was first formally described in 1787 as ''Scorpaena antennata'' by the German physician and naturalist Marcus Elieser Bloch with the type locality given as Ambon Island in Indonesia. The specific name ''antennata'' means ”with antennae”, an allusion to the supraorbital tentacles. Description ''Pterois antennata'' has a laterally compressed rather deep body. There are 13 spines and 11 or 12 soft rays in the dorsal fin and 3 spines and 6 soft rays in its anal fin. There is a long tentacle above each eye. Coronal spines are present and there are many head spines.There are 17 simple fin rays in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterois
''Pterois'' is a genus of venomous marine fish, commonly known as lionfish, native to the Indo-Pacific. Also called firefish, turkeyfish, tastyfish, or butterfly-cod, it is characterized by conspicuous warning coloration with red, white, creamy, or black bands, showy pectoral fins, and venomous, spiky fin rays. '' Pterois radiata'', ''Pterois volitans'', and '' Pterois miles'' are the most commonly studied species in the genus. ''Pterois'' species are popular aquarium fish. ''P. volitans'' and ''P. miles'' are recent and significant invasive species in the west Atlantic, Caribbean Sea and Mediterranean Sea. Taxonomy ''Pterois'' was described as a genus in 1817 by German naturalist, botanist, biologist, and ornithologist Lorenz Oken. In 1856 the French naturalist Eugène Anselme Sébastien Léon Desmarest designated ''Scorpaena volitans'', which had been named by Bloch in 1787 and which was the same as Linnaeus's 1758 ''Gasterosteus volitans'', as the type species of th ...

Crustacea
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by ...
