Machilidae
The Machilidae are a family of insects belonging to the order Archaeognatha (the bristletails). There are around 250 described species worldwide. These insects are wingless, elongated and more or less cylindrical with a distinctive humped thorax and covered with tiny, close-fitting scales. The colour is usually grey or brown, sometimes intricately patterned. There are three "tails" at the rear of the abdomen: two cerci and a long central epiproct. They have large compound eyes, often meeting at a central point. They resemble the silverfish and the firebrat, which are from a different order, Zygentoma. Machilids undergo virtually no metamorphosis during their life cycles, and both nymphs and adults are generally inconspicuous herbivores and scavengers. Many species are restricted to rocky shorelines, but some are found in well-vegetated habitats inland. They can move very fast and often escape by jumping considerable distances when disturbed. Like all Archaeognatha, machilid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrobius Maritimus
''Petrobius maritimus'', the shore bristletail or sea bristletail, is a species of Archaeognatha found on rocky shores from the Mediterranean Sea to the North Sea The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian S ... . Individuals may grow up to 15 mm and are grey in colour, with long bristly antennae and a triple forked tail . They are very resistant to low temperatures, and remains active even if the temperature drops below 0 degrees C.

Jumping Bristletail
The Archaeognatha are an order of apterygotes, known by various common names such as jumping bristletails. Among extant insect taxa they are some of the most evolutionarily primitive; they appeared in the Middle Devonian period at about the same time as the arachnids. Specimens that closely resemble extant species have been found as both body and trace fossils (the latter including body imprints and trackways) in strata from the remainder of the Paleozoic Era and more recent periods. For historical reasons an alternative name for the order is Microcoryphia. Until the late 20th century the suborders Zygentoma and Archaeognatha comprised the order Thysanura; both orders possess three-pronged tails comprising two lateral cerci and a medial epiproct or ''appendix dorsalis''. Of the three organs, the appendix dorsalis is considerably longer than the two cerci; in this the Archaeognatha differ from the Zygentoma, in which the three organs are subequal in length. In the late 20th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shore
A shore or a shoreline is the fringe of land at the edge of a large body of water, such as an ocean, sea, or lake. In physical oceanography, a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. In contrast to a coast, a shore can border any body of water, while the coast must border an ocean or a sea. Therefore, in that sense, a coast is a type of shore. However, the word "coast" often refers to an area far wider than the shore, often stretching miles into the interior. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore which is created. Rivieras ''Riviera'' is an Italian word for "shoreline", ultimately derived from Latin ''ripa'' ("riverbank"). It came to be applied as a proper n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
