Albert William Herre
Albert William Christian Theodore Herre (September 16, 1868 – January 16, 1962) was an American ichthyologist and lichenologist. Herre was born in 1868 in Toledo, Ohio. He was an alumnus of Stanford University, where he received a Bachelor of Science degree in botany in 1903. Herre also received a master's degree and a Ph.D. from Stanford, both in ichthyology. He died in Santa Cruz, California in 1962. Work in the Philippines Albert W. Herre was perhaps best known for his Taxonomy (biology), taxonomic work in the Philippines, where he was the Chief of Fisheries of the Bureau of Fisheries and Aquatic Resources, Bureau of Science in Manila from 1919 to 1928. While in the Bureau of Science of the Insular Government of the Philippine Islands (which were administered by the United States at the time), Herre was responsible for discovering and describing many new species of fish. Legacy Herre is commemorated in the scientific name of a species of gecko, ''Lepidodactylus herrei'', wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caudal 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 to lu ...

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] |
Demersal
The demersal zone is the part of the sea or ocean (or deep lake) consisting of the part of the water column near to (and significantly affected by) the seabed and the benthos. The demersal zone is just above the benthic zone and forms a layer of the larger profundal zone. Being just above the ocean floor, the demersal zone is variable in depth and can be part of the photic zone where light can penetrate, and photosynthetic organisms grow, or the aphotic zone, which begins between depths of roughly and extends to the ocean depths, where no light penetrates. Fish The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (''Gadus morhua'') is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (''Clupea harengus'') is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel. Two types of fish inhabit the demersal zone: those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Oxudercidae
Oxudercidae is a family of gobies which consists of four subfamilies which were formerly classified under the family Gobiidae. The family is sometimes called the Gobionellidae, but Oxudercidae has priority. The species in this family have a cosmopolitan distribution in temperate and tropical areas and are found in marine and freshwater environments, typically in inshore, euryhaline areas with silt and sand substrates. The Oxudercidae includes 86 genera, which contain around 600 species. This family has many species which occur in fresh water, and a number of species found on wet beaches and are able to live for a number of days out of water. The family includes the mudskippers, which include species that are able to move over land with quite quickly. They have eyes located on the top of their heads on short stalks. They are capable of elevating or retracting them, and they can see well out of water. One species, ''Gillichthys mirabilis'', usually stays in the water, but surfaces t ...

Gobionellinae
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of '' Fishes of the World'' classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus '' Gnatholepis'', which live with corals in marine environments.Larson, H. K. and D. J. Buckle. (2012)A revision of the goby genus ''Gnatholepis'' Bleeker (Teleostei, Gobiidae, Gobionellinae), with description of a new species.''Zootaxa'' 3529: 1–69. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.

Schismatogobius
''Schismatogobius'' is a genus of fish in the subfamily Gobionellinae. They are native to southern and eastern Asia, Australia and the Pacific Islands. Adults dwell in freshwater habitat such as streams and rivers, where they live along the sand and gravel substrates. These fish are not always obvious in the habitat, because they are small and cryptic. They lack scales and have variable color patterns, with no two individuals of a given species alike. Compared to those of females, the jaws of males are "hugely large".

Ichthyologist
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most usef ...

Ventral Fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.
