Bird Wrasse
The bird wrasse, ''Gomphosus varius'', is a species of the wrasse family. Description The bird wrasse is a medium-sized fish which can reach a standard length of . It has an elongated body, laterally compressed, with a truncated tail and a long snout. Adults are relatively easy to recognize by their characteristic long nose and the jerky flapping of their pectoral fins when swimming. Juveniles are more difficult to identify, as they haven't yet developed the characteristic prominent snout.Myers, R.F., 1999. Micronesian reef fishes: a comprehensive guide to the coral reef fishes of Micronesia, 3 rd revised and expanded edition. Coral Graphics, Barrigada, Guam. 330 p. ''Gomphosus varius'' can be confused with its close relative ''Gomphosus caeruleus'', but differs from the latter by its color pattern and its geographic range. Like many wrasses, ''Gomphosus varius'' is a sequential hermaphrodite. As it changes sex, its body shape, color intensity and pattern vary considerably. T ...

Bernard Germain De Lacépède
Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French natural history, naturalist and an active freemason. He is known for his contribution to the Comte de Buffon's great work, the ''Histoire Naturelle''. Biography Lacépède was born at Agen in Guienne. His education was carefully conducted by his father, and the early perusal of Georges-Louis Leclerc, Comte de Buffon, Buffon's Natural History (''Histoire naturelle, Histoire naturelle, générale et particulière'') awakened his interest in that branch of study, which absorbed his chief attention. His leisure he devoted to music, in which, besides becoming a good performer on the piano and organ, he acquired considerable mastery of composition, two of his operas (which were never published) meeting with the high approval of Christoph Willibald Gluck, Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''.

Crustaceans
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of Arthropod, arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic animal, aquatic arthropods including decapoda, decapods (shrimps, prawns, crabs, lobsters and crayfish), ostracoda, seed shrimp, branchiopoda, branchiopods, argulidae, fish lice, krill, remipedes, isopods, barnacles, copepods, Mysida, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the Hexapoda, hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans (oligostracans and multicrustaceans). The 67,000 described spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Palau
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Gomphosus
''Gomphosus'' is a small genus of wrasses native to the Indian and Pacific Oceans. Taxonomy Although classified as its own genus, the genus ''Gomphosus'' is nested within the genus ''Thalassoma'', rendering the latter paraphyletic. This close affinity is reflected by the fact that in the wild, ''Gomphosus'' will sometimes create hybrid Hybrid may refer to: Science * Hybrid (biology), an offspring resulting from cross-breeding ** Hybrid grape, grape varieties produced by cross-breeding two ''Vitis'' species ** Hybridity, the property of a hybrid plant which is a union of two diff ... offspring with ''Thalassoma'' species.

Saddle Wrasse
The saddle wrasse (''Thalassoma duperrey''), also known as Hīnālea Lauwili in Hawaiʻi, is a species of wrasse native to the waters around the Hawaiian Islands and Johnston Island. They are found on reefs at depths from . This species can reach in total length. This species can also be found in the aquarium An aquarium (: aquariums or aquaria) is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. fishkeeping, Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquati ... trade. Description Adults of the saddle wrasse have a dark blue-green head followed by a dull orange band that will intensify during the spawning seasons, as for the rest of the body it is blue-green with numerous magenta arrows running down the sides. Terminal males typically have a white bar around the orange band that is able to be turned on or off, as well as a crescent-shaped tail fin. Juveniles tend to be more whiti ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Protogynous Hermaphrodite
Sequential hermaphroditism (called dichogamy in botany) is one of the two types of hermaphroditism, the other type being simultaneous hermaphroditism. It occurs when the organism's sex changes at some point in its life. A sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Sequential hermaphroditism occurs in many fish, gastropods, and plants. Species that can undergo these changes do so as a normal event within their reproductive cycle, usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), and bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex chang ...
