Halobates Germanus
''Halobates'', colloquially the sea skaters or ocean striders, are a genus with over 40 species of water striders. Most ''Halobates'' species are coastal and typically found in sheltered, coastal marine habitats (a habitat where a few other genera of water striders also live), but five live on the surface of the open ocean and only occur near the coast when storms blow them ashore. These are the only known truly oceanic, offshore insects. They are found in tropical and subtropical marine habitats around the world, with a single species recorded in rivers a few kilometers upstream from the ocean. ''Halobates'' are generally very abundant where they are found. Discovery They were first collected by Johann Friedrich von Eschscholtz, a doctor who was part of a Russian expedition aboard the ''Rurik'' between 1815 and 1818. A fossil species, ''H. ruffoi'', is known from 45 million year old deposits in Verona, Italy. Description ''Halobates spp.'' are small insects with a body that ...

Indo-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. 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. As a distinct marine realm, 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 all directions. The region includes over 3,000 species of fish, compared with around 1,200 in the next richest marine region, the Western Atlantic, and around 500 species of reef building corals, compar ...

Halobates Micans
''Halobates micans'' is a species of sea skater in the family Gerridae. Being a member of ''Halobates'', it is exclusively marine, though unlike the other species that are restricted to the Indian and/or Pacific Oceans, ''H. micans'' is circumglobal, occurring offshore in warmer seas around the world; this species is the only ''Halobates'' found in the Atlantic Ocean (including the Caribbean) where it ranges from about 40° north to 40° south. ''Halobates'' is the only type of insect present in the open ocean, despite at least 14 orders of insect being present in marine environments. Description As a member of the genus ''Halobates'', it lives out its entire life in marine environments; specifically, it is one of five ''Halobates'' species that live on the surface of the open ocean, only occurring near the coast when storms blow them ashore; the other species are '' H. germanus'', '' H. sericeus'', '' H. sobrinus'', and '' H. splendens''.

Ecological Niche
In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of Resource (biology), resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another [and] the relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". See also Chapter 2: Concepts of niches, pp. 7 ''ff'' A Grinnellian niche is determined by the habitat in which a species lives and its accompanying Behavioral ecology, behavioral adaptations. ...

Veliidae
Veliidae is a family (biology), family of gregarious predatory insects in the suborder Heteroptera. They are commonly known as riffle bugs, small water striders, or broad-shouldered water striders because the segment immediately behind the head is wider than the rest of the abdomen. Species of the genus ''Rhagovelia'' are also referred to as ripple bugs. Veliidae have a specialized body plan that allows them to walk on water and are neuston. The family Gerridae is another closely related group that is also neuston and both are in the Taxonomic rank, superfamily Gerroidea. Veliidae are smaller however, between . They can be found on ponds, near lake shores, and in rivers worldwide. Some species can also be found on plants near water, in salt water or in mud flats. Description Veliidae are very similar to Gerridae. The most consistent characteristic used to separate these two families are internal Sex organ, genitalia differences, however external cues are usually sufficient to te ...

Trochopus (bug)
Capsalidae Yamaguti, S. (1963) Systema Helminthum IV. Monogenea and Aspidocotylea. London-New York, Interscience Publishers. 699 pp. is a family of monopisthocotylean monogeneans, which includes about 200 species. The monophyly of the Capsalidae is supported by possession of accessory sclerites in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. Their oncomiracidium (the free larva) is distinct from that of other families. Capsalids are parasite on various organs of marine fish (teleosts and elasmobranchs), including skin, fins and gills. Several capsalid species, such a '' Neobenedenia'' spp. are pathogenic, especially on maricultured fish. Included genera Genera as recognized iWorMsare listed below. Recent molecular analyses have shown that several genera, which were defined on morphological characters, are not monophyletic. '' Menziesia'' and ''Nitzschia'' have their equivalent in the botanical nomenclature: '' Menziesia'' (a flowerin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daly River (Northern Territory)
The Daly River is a river in the Northern Territory of Australia. It is part of the Daly Catchment. The Daly River flows from the confluence of the Flora River and Katherine River to its mouth on the Timor Sea. It is one the few major rivers in the Northern Territory that flows all year round. Sustained by groundwater, its dry-season flows are five time larger than any other river in the territory. It is home to more than 90 species of fish. It is best known for its large barramundi making it a popular waterway for recreational fishing. The floodwater carries baitfish which attracts predatory barramundi. The river is also home to the critically endangered largetooth sawfish. It also has eight different turtle species, includes the endangered pig-nosed turtle, more than any other Australian river. History The traditional owners of the river and surrounding area are the Wadjigiynk, Marranunggu, Maranunngu, Malak Malak, Kamu, Warai, Nanggiwumerri, Wagiman, Wardaman people, Wardam ...
