Macolor
''Macolor'' is a genus of marine ray-finned fish, snappers belonging to the family Lutjanidae. They are native to the Indian Ocean and the western Pacific Ocean. Taxonomy ''Macolor'' was described as a genus in 1860 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker. Bleeker used the name ''Macolor'' tautonymously as the type species was Cuvier’s ''Diacope macolor'' which Bleeker renamed, needlessly, ''Macolor typus''. The name may be derived from ''macula'', Latin for “spot” a reference to the white spotting on the otherwise black body of the juveniles of ''M. niger''. The genus is placed within the subfamily Lutjaninae. Species The currently recognized species in this genus are: * ''Macolor macularis'' Fowler, 1931 (midnight snapper) * ''Macolor niger'' ( Forsskål, 1775) (black and white snapper) Characteristics ''Macolor'' snappers are medium-sized with a relatively deep, oblong body. They have quite a large mouth which can be ptrotracted. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macolor Macularis
''Macolor macularis'', the midnight snapper, midnight seaperch or black and white snapper, is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is native to the Indian and western Pacific Oceans. Taxonomy ''Macolor macularis'' was first formally described in 1931 by the American ichthyologist Henry Weed Fowler with the type locality given as near Ragay Gulf on Luzon. The specific name ''macularis'' means “spotted”, presumed to be a reference to the description stating “most every scale with gray or blue spot”. Description ''Macolor macularis'' has a moderately deep body with a rather convex forehead with a large mouth. The preoperculum has a deep incision on its lower margin. There is a row of conical teeth in the jaws, the ones in the front are enlarged and there are bands of bristle-like teeth on sides of upper jaw and front of lower jaw inside the outer row. The vomerine teeth are arranged in a roughly chevron shaped patch. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macolor Niger
The black and white snapper (''Macolor niger''), the black and white seaperch or black snapper, is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is native to the Indian Ocean and the western Pacific Ocean. Taxonomy The black and white snapper was first formally described in 1775 as ''Sciaena nigra'' by the Swedish speaking Finnish-born explorer and naturalist Peter Forsskål with the type locality given as Jeddah. The specific name ''niger'' means “black”, a reference to the blackish colour of the adults. When the genus ''Macolor'' was described in 1860, by the Dutch physician, herpetologist and ichthyologist, Pieter Bleeker, he used the name ''Macolor'' tautonymously, for the type species which was Cuvier’s ''Diacope macolor''. Bleeker needlessly renamed ''D. macolor'', ''Macolor typus''. Description The black and white snapper has a relatively deep body. It has a convex dorsal profile of the head and a large mouth which e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutjanidae
Lutjanidae, or snappers are a family of perciform fish, mainly marine, but with some members inhabiting estuaries, feeding in fresh water. The family includes about 113 species. Some are important food fish. One of the best known is the red snapper. Snappers inhabit tropical and subtropical regions of all oceans. Some snappers grow up to about in length however one specific snapper, the cubera snapper, grows up to in length. Most are active carnivores, feeding on crustaceans or other fish, though a few are plankton-feeders. They can be kept in aquaria, but mostly grow too fast to be popular aquarium fish. Most species live at depths reaching near coral reefs, but some species are found up to deep. As with other fish, snappers harbour parasites. A detailed study conducted in New Caledonia has shown that coral reef-associated snappers harbour about 9 species of parasites per fish species.

Lutjaninae
Lutjaninae is a subfamily of marine ray-finned fishes, one of four subfamilies classified within the family Lutjanidae, the snappers. Genera The subfamily Lutjaninae contains 6 genera and 76 species: * genus '' Hoplopagrus'' Gill, 1861 * genus ''Lutjanus'' Bloch, 1790 * genus ''Macolor'' Bleeker, 1860 * genus '' Ocyurus'' Gill, 1862 * genus '' Pinjalo'' Bleeker, 1873 * genus '' Rhomboplites'' Gill, 1862 A taxonomic study of snappers within the subfamily Lutjaninae in the tropical western Atlantic Ocean indicated that the monotypic genera ''Ocyurus'' and ''Rhomboplites'' sit within the genus ''Lutjanus''. Fossil history The Lutjaninae are represented in the fossil record as far back as the 48.6 million years ago from the Eocene where specimens have been found in the United Kingdom and Louisiana. More recent specimens are known from the Miocene in Mexico and Florida and the Quaternary of the Turks and Caicos Islands The Turks and Caicos Islands (abbreviated TCI; and ) ar ...

Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Duméril of Paris. His wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crustaceans
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 th ...

Crinoids
Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths as great as . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have a ...

Ryukyu Islands
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs. The Ōsumi and Tokara Islands, the northernmost of the islands, fall un ...

Emarginate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectoral Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod ...
