Aletopauropus Tanakai
''Aletopauropus'' is a genus of pauropods in the family Brachypauropodidae. This genus includes only two species: the type species, '' A. lentus'', which is found in California, and a second species, '' A. tanakai'', which is found in Japan. This genus is notable as one of only four genera of pauropods in which adults have only eight pairs of legs rather than the nine leg pairs usually found in adults in the order Tetramerocerata. Before the discovery of ''Aletopauropus'', adult pauropods were described as having only nine or (rarely) ten pairs of legs. Discovery and distribution The genus ''Aletopauropus'' and its type species ''A. lentus'' were first described in 1948 by the zoologists John W. MacSwain and Urless N. Lanham of the University of California at Berkeley. MacSwain and Lanham based their descriptions on twelve specimens that MacSwain collected in 1947. These specimens include a male holotype, a female allotype, seven paratypes (one male and six females), and thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juvenile (organism)
A juvenile is an individual organism (especially an animal) that has not yet reached its adult form, sexual maturity or size. Juveniles can look very different from the adult form, particularly in colour, and may not fill the same niche as the adult form. In many organisms the juvenile has a different name from the adult (see List of animal names). Some organisms reach sexual maturity in a short metamorphosis, such as ecdysis in many insects and some other arthropods. For others, the transition from juvenile to fully mature is a more prolonged process—puberty in humans and other species (like higher primates and whales), for example. In such cases, juveniles during this transformation are sometimes called subadults. Many invertebrates cease development upon reaching adulthood. The stages of such invertebrates are larvae or nymphs. In vertebrates and some invertebrates (e.g. spiders), larval forms (e.g. tadpoles) are usually considered a development stage of their own, an ...

Seta
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, Scale (insect anatomy), scales, or Common name, informally, hairs. The setal membrane is not Cuticle, cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (the group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemos ...
