Neosomy
Neosomy is the formation of new external structure in an active stage of an invertebrate, in a taxon that normally only changes during moulting. It occurs in nematodes and a wide range of arthropods, especially those with symbiotic lifestyles. An organism that has undergone neosomy is a neosome, while a new external structure formed by neosomy is a neosomule. Neosomy is similar to physogastrism (or physogastry) and the two phenomena are sometimes confused. However, physogastrism is usually defined as distension of the abdomen, without the growth of new cuticle. Examples Acari Larvae of some chiggers can increase in size massively via neosomy, such as '' Vatacarus'' (from sea kraits) enlarging by 1500 times or more, and '' Riedlinia'' (from bats) by up to 750 times. Other mites with neosomatic larvae include ''Trombidium'', '' Eutrombidium'' and the aquatic ''Eylais'' and '' Hydrachna''. In ticks of family Ixodidae, the larvae, nymphs and adult females show neosomy. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Argasidae
The Argasidae are the family of soft ticks, one of the three families of ticks. The family contains 193 species, although the composition of the genera is less certain, and more study is needed before the genera can become stable. The currently accepted genera are '' Antricola'', '' Argas'', '' Nothoaspis'', ''Ornithodoros'', and '' Otobius''. The Argasidae are very common in South Asia, along with 96 other species of ticks, making South Asia the region with the highest biodiversity of ticks worldwide. Soft ticks are resistant to desiccation and can live for several years in arid conditions. Physical characteristics Soft ticks lack the hard scutum present in the hard ticks (Ixodidae). The gnathosoma (or capitulum, the mouthparts-bearing structure) is located on the underside of the animal's body and is not readily visible, while in the Ixodidae, the gnathosoma projects forward from the body. The lateral edges of the body are rounded. See also *Ticks of domestic animals Ticks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lernaea
''Lernaea'' is a genus of copepod crustaceans whose members are commonly called ''anchor worms'' and are parasitic on freshwater fishes. Life cycle Anchor worms mate during the last free-swimming (copepodid) stage of development. After mating, the female burrows into the flesh of a fish and transforms into an unsegmented, wormlike form, usually with a portion hanging from the fish's body. Eggs are released from the posterior "tails" (egg sacs) into the water, where they hatch within 24 to 36 hours. The nauplii will go through three stages before molting into copepodids, which associate with fish gills. After a further five stages and mating, the male leaves the host and dies, while the female transitions into the anchored stage (may move to different fish host). Diagnosis Symptoms of anchor worm can be as follows: # Anchor worms (''Lernaea'' sp.) can be seen with the naked eye # Frequent rubbing or "flashing" # Localised redness # Inflammation on the body of the fish # Tiny ...

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rove Beetle
The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus ''Leehermania'' proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems. One well-known species is the devil's coach-horse beetle. For some other species, see list of British rove beetles. Anatomy As might be expected for such a large family, considerable variation exists among the species. Sizes range from <1 to , with most in the 2–8 mm range, and the form is generally elongated, with some rove beetles being ovoid i ...

Phoridae
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to '' Conicera tibialis''. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan ''Megaselia scalaris''. At 0.4 mm in length, the world's smallest fly is the phorid ''Euryplatea nanaknihali''. Description For terms see Morphology of Diptera Phorid flies are minute or small – 0.5–6 mm (– in) in length. When viewed from the side, a pronounced hump to the thorax is seen. Their colours range from usually black or brown to more rarely yellow, orange, pale grey, and pale white. The head is usually rounded and in some species narrowed towards the vertex. The vertex is flat. In some species, the ocellar callus i ...

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Hippoboscidae
__NOTOC__ Hippoboscidae, the louse flies or keds, are obligate parasites of mammals and birds. In this family, the winged species can fly at least reasonably well, though others with vestigial or no wings are flightless and highly apomorphic. As usual in their superfamily Hippoboscoidea, most of the larval development takes place within the mother's body, and pupation occurs almost immediately. The sheep ked, ''Melophagus ovinus'', is a wingless, reddish-brown fly that parasitizes sheep. The Neotropical deer ked, ''Lipoptena mazamae'', is a common ectoparasite of white-tailed deer (''Odocoileus virginianus'') in the southeastern United States. Both winged and wingless forms may be seen. A common winged species is ''Hippobosca equina'', called "the louse fly" among riders. Species in other genera are found on birds; for example, ''Ornithomya bequaerti'' has been collected from birds in Alaska. Two species of the Hippoboscidae – '' Ornithoica (Ornithoica) podargi'' and ''Ornit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
