NationMaster - Encyclopedia: Jumping spider

The jumping spider family (Salticidae) contains more than 500 described genera and over 5,000 species, making it the largest family of spiders with about 13% of all species (Peng et al., 2002). Jumping spiders have good vision and use it for hunting and navigating. They are capable of jumping from place to place, secured by a silk tether. Both their book lungs and the tracheal system are well-developed, as they depend on both systems (bimodal breathing). For other uses, see Species (disambiguation). ... For other uses, see Spider (disambiguation). ... Spider silk is a fibre secreted by spiders. ... A book lung is a type of respiration organ used for atmospheric gas exchange and is found in arachnids, such as scorpions and spiders. ...

Habitat

Jumping spiders live in a variety of habitats. Tropical forests harbor the most species, but they are also found in temperate forests, scrub lands, deserts, the intertidal zone (in Malaysia), even mountains one species is reported to have been the spider collected at the highest elevation, on the slopes of Mt. Everest (Wanless, 1975). Certain species of Salticidae are quite common in Europe, such as the Zebra Jumping Spider Salticus scenicus, which is commonly found resting on sun-warmed stone or brick walls.

Appearance

Jumping spiders are generally recognized by their eye pattern. They typically have eight eyes arranged in two or three rows. The front, and most distinctive row is enlarged and forward facing to enable stereoscopic vision. The others are situated back on the cephalothorax. For other uses, see Eye (disambiguation). ... Binocular vision (also referred to as stereoscopic vision) is a type of visual system common in many kinds of animals where both the eyes produce only a single image in the brain. ... The cephalothorax is an anatomical term used of arachnid and malacostracan arthropods for the first major body section. ...

Colours and patterns vary widely. Several species of jumping spiders appear to mimic ants, beetles, or pseudoscorpions. Others may appear to be parts of grass stems, bumps on twigs, bark, part of a rock or even part of a sand surface.

For other uses, see Grass (disambiguation). ...

Behavior

Jumping spiders are generally diurnal, active hunters. Their well developed internal hydraulic system extends their limbs by altering the pressure of body fluid (blood) within them. This enables the spiders to jump without having large muscular legs like a grasshopper. The jumping spider can therefore jump 20 to 60 or even 80 times the length of their body. When a jumping spider is moving from place to place, and especially just before it jumps, it tethers a filament of silk to whatever it is standing on. Should it fall for one reason or another, it climbs back up the silk tether. A diurnal animal (dÄ«-ÅrnÉ™l) is an animal that is active during the daytime and sleeps during the night. ... Table of Hydraulics and Hydrostatics, from the 1728 Cyclopaedia. ... For other uses, see Grasshopper (disambiguation). ...

Unlike almost all other spiders, they can quite easily climb on glass. Minute hairs and claws on their feet enable them to grip imperfections in the glass.

Jumping spiders also use their silk to weave small tent-like dwellings where females can protect their eggs, and which also serve as a shelter while moulting. In most birds and reptiles, an egg (Latin ovum) is the zygote, resulting from fertilization of the ovum. ... Ecdysis is the molting of the cuticula in arthropods and related groups (Ecdysozoa). ...

Jumping spiders are known for their curiosity. If approached by a human hand, instead of scuttling away to safety as most spiders do, the jumping spider will usually leap and turn to face the hand. Further approach may result in the spider jumping backwards while still eyeing the hand. The tiny creature will even raise its forelimbs and "hold its ground." Because of this contrast to other arachnids, the jumping spider is regarded as inquisitive as it is seemingly interested in whatever approaches it.^{[citation needed]} This article does not cite any references or sources. ...

Vision

Jumping spiders have very good vision centered in their anterior median eyes (AME). Their eyes are able to create a focused image on the retina, which has up to four layers of receptor cells in it (Harland & Jackson, 2000). Physiological experiments have shown that they may have up to four different kinds of receptor cells, with different absorption spectra, giving them the possibility of up to tetrachromatic color vision, with sensitivity extending into the ultra-violet range. It seems that all salticids, regardless of whether they have two, three or four kinds of color receptors, are highly sensitive to UV light (Peaslee & Wilson, 1989). Some species (for example, Cosmophasis umbratica) are highly dimorphic in the UV spectrum, suggesting a role in sexual signaling (Lim & Li, 2005). Color discrimination has been demonstrated in behavioral experiments. In psychology, visual perception is the ability to interpret information from visible light reaching the eyes. ... In zootomy, several terms are used to describe the location of organs and other structures in the body of bilateral animals. ... Electromagnetic radiation may be characterised by its wavelength. ... A tetrachromat is an organism for which the perceptual effect of any arbitrarily chosen light from its visible spectrum can be matched by a mixture of no more than four different pure spectral lights. ... Color vision is the capacity of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect or emit. ... Note: Ultraviolet is also the name of a 1998 UK television miniseries about vampires. ... Note: Ultraviolet is also the name of a 1998 UK television miniseries about vampires. ... Binomial name Simon, 1903 Species see text Cosmophasis umbratica is a species of jumping spider that occurs from India to Sumatra. ... Male and female Common Pheasant, illustrating the large degree of sexual dimorphism between the sexes Sexual dimorphism is the systematic difference in form between individuals of different sex in the same species. ...

The principal eyes have high resolution (11 min. visual angle) [1], but the field of vision is narrow, from 2-5 degrees.

Because the retina is the darkest part of the eye and it moves around, one can sometimes look into the eye of a jumping spider and see it changing color. When it is darkest, you are looking into its retina and the spider is looking straight at you.[2]

Diet

Hunting

Jumping spiders capture their prey by jumping on it from several inches away, and they may jump from twig to twig or leaf to leaf. They can jump many times their body length. They can carry out complex maneuvers such as detours around obstacles in order to reach their prey. Their eyesight is much better than the other spiders and most, if not all, insects. Most other spiders will only eat prey that they have captured live because they are unable to see dead prey (some long-legged sac spiders and anyphaenid sac spiders are exceptions as they recognize insect eggs as food) but jumping spiders will eat flies that have been killed for them. One jumping spider (Evarcha culicivora) is even known to only capture mosquitos full of blood, using their eyesight and smell. Genera many, see text The long-legged sac spiders (family Miturgidae) include nearly 400 species in about 30 genera worldwide. ... Genera Anyphaena Hibana The anyphaenid sac spiders of the family Anyphaenidae are distinguished from the sac spiders and other spiders by having the abdominal spiracle placed one third to one half of the way anterior to the spinnerets toward the epigastric furrow on the underside of the abdomen. ... Binomial name Evarcha culicivora Wesolowska & Jackson, 2003 Evarcha culicivora is a species of jumping spider from Kenya. ... For other uses, see Mosquito (disambiguation). ...

Nectar and pollen

Even if there are no spiders that are pure herbivores, there are some jumping spiders which include nectar and pollen in their diet (Jackson et al., 2001). So far none are known to feed on seeds. When insects land on plants such as the partridge pea, which offers the spiders nectar through their extrafloral nectaries, the jumping spiders help protect the plant in return by killing and eating insects that might damage the plant. A deer and two fawns feeding on some foliage A herbivore is often defined as any organism that eats only plants[1]. By that definition, many fungi, some bacteria, many animals, about 1% of flowering plants and some protists can be considered herbivores. ... In Greek mythology, nectar and ambrosia are the food of the gods. ... SEM image of pollen grains from a variety of common plants: sunflower (Helianthus annuus), morning glory (Ipomoea purpurea), prairie hollyhock (Sidalcea malviflora), oriental lily (Lilium auratum), evening primrose (Oenothera fruticosa), and castor bean (Ricinus communis). ...

Gliding

At least one species of jumping spiders, known as the Gliding Spider (Maratus volans) from Australia, has an abdomen with two wing-like flaps that can be tucked underneath it when not in use. When the spider is leaping, it can use its flaps to extend the jump and glide short distances through the air. Binomial name Maratus volans (O. P-Cambridge, 1874) Synonyms Saitis volans Maratus amoenus The Gliding spider (Maratus volans) is a species of jumping spider. ...

Venom

Some jumping spiders may bite to protect themselves if disturbed. However, jumping spiders usually escape and hide, and will only bite if provoked and cornered. While the bite of a larger jumping spider can be painful, only a few species produce any other effects. Almost all spiders (except hackled orb-weavers) have venom, but the venom of most spiders is no worse than the venom of a bee. For more information of envenomation see the Spider bite article. Genera Ariston (spider) Astavakra Conifaber Daramulunia Hyptiotes Lubinella Miagrammopes Octonoba Orinomana Philoponella Polenecia Purumitra Siratoba Sybota Tangaroa Uloborus Waitkera Zosis The hackled orbweavers (family Uloboridae) have the special distinction of being non-venomous spiders. ...

Reproduction

Jumping spiders use their vision in complex visual courtship displays. Males are often quite different in appearance than females and may have plumose hairs, colored or metallic hairs, front leg fringes, structures on other legs and other, often bizarre, modifications. These are used in visual courtship in which the colored or metallic parts of the body are displayed and complex sideling, vibrational or zigzag movements are performed in a courtship "dance." A 2008 study of Phintella vittatain in Current Biology suggested that female spiders reacted to the male reflecting ultraviolet B light before mating, a finding that challenges the previously held assumption that animals did not register ultraviolet B light.^[1] In recent years it has been discovered that many jumping spiders may have auditory signals as well, with amplified sounds produced by the males sounding like buzzes or drum rolls.^{[citation needed]} UV redirects here. ...
