   Extractions: Uropygi Arachnids are a class ( Arachnida ) of joint-legged invertebrate animals in the subphylum Chelicerata . The term arachnid is from the Greek word άράχνη or arachne , meaning spider, and also referring to the mythological figure Arachne . They are chiefly terrestrial arthropods , comprising some 65,000 to 73,000 named species including spiders scorpions harvestmen ticks , and mites It is commonly understood that arachnids have four pairs of legs, and that arachnids may be easily distinguished from insects by this fact (insects have six legs or three pairs). Interestingly, arachnids generally have a total of 6 pairs of appendagestwo pairs of which have become adapted for feeding, defense, and sensory perception. The first pair of appendages, the chelicerae , serve in feeding and defense. The next pair of appendages, the

Click here to find out more... Arachnid, term for animals in the class including the scorpions, spiders, daddy longlegs, mites, and ticks, and certain other eight-legged land invertebrates. Fossils suggest that arachnids were among the first animals to live on land, perhaps in the early Devonian Period, nearly 400 million years ago. About 60,000 species are known, although many, especially mites, remain undiscovered or undescribed. Arachnids are found throughout the world in nearly every habitat, but they reach their greatest size and diversity in warm arid and tropical regions. Characteristics The arachnid body is divided into two parts: anterior and posterior. The anterior part, called the cephalothorax, contains sense organs, mouthparts, and limbs in pairs. The first pair of limbs-the chelicerae-may form pincers or poison fangs, and the second pair-the pedipalps-may serve as pincers, feelers, or legs. The other limb pairs, generally four, are used for walking. The posterior part of the body, the abdomen, bears the genital opening and other structures. It is usually equipped with modified gills called book lungs. Most arachnids are solitary except at the time of mating, when a variety of complex behavior patterns may be observed. Females may guard eggs or young, which are often born live.

   Extractions: Arachnid are animals that have an exoskeleton, a two-part segmented body, and 8 jointed legs; they do not have a backbone. The body is divided into the prosoma and the abdomen. The prosoma anchors the chelicerae (pincers), pedipalps (mouth parts) and four pairs of legs. Arachnid are aggressive predators. They are cold-blooded; their body temperature depends on the temperature of their environment. Arachnids breathe air through book-lungs, gill-like structures.

   Extractions: Arachnids are a type of arthropod. You know many of them as spiders. Like other arthropods, the arachnids have a hard exoskeleton and jointed appendages for walking. Unlike other arthropods, arachnids do not have antennae. Common arachnids are the spider, scorpions, ticks and mites. Enter your search terms Submit search form Web www.kidport.com Invertebrate Animals Vertebrate Animals The Animal Kingdom Web Links ... Science Main Index Spiders have 8 appendages. The first pair are used for holding the prey and feeding. The second pair may also be used for holding and killing their prey. The others are used as legs for walking. Most spiders also have 8 eyes. Spiders have fangs that are used to inject poison to paralyze or kill their prey. Many spiders can produce silk threads to spin webs for catching prey, and for building cocoons for their eggs. Scorpions are the largest arachnids, some reaching over 8 inches in length. They have 6 to 12 appendages. They also have a sharp stinger at the end of their tail which is used to paralyze or kill insects and small animals. Mites and ticks are small arachnids that are parasites living on the blood and tissue fluid of other animals. They can occasionally transmit disease.

   Extractions: Also known as "Sun Spiders" these voracious nocturnal predators live in warm, arid regions of the world. Solpugids feed upon a variety of small animals including vertebrates. Solpugids eat much more than other arachnids of comparable size and are thus quite beneficial as a limiting factor for potentially destructive organisms. These quarter inch arachnids emerge following the first heavy summer rains, coinciding with the emergence of winged termites on their nuptial flight. These are the velvet mite's sole food. Termites provide rich nutrients which allow for a brief visit to the surface to feed, mate, lay eggs and return to the soil.

Unlike insects, the body is separated into only 2 parts. The cephalothorax, also known as the prosoma, contains the mouth area as well as the chelicerae (pincers or claws used for feeding), pedipalpi (feet used to touch or capture) and 8 legs, four on either side. Arachnids lack antannae. The cephalothorax is partially or completely covered with a protective shield. The second segment is known as the abdomen or opisthosoma, and contains the rest of the body. The abdomen may lack appendages entirely, or it may have specialized appendages, such as the spinneret used to make spiderwebs. Most arachnids breath in through tracheae or book lungs. Most arachnid species are considered to be pests or are thought to be dangerous to humans.some spiders can kill humans, but these occurrences are very rare. Scorpions are also poisonous, and ticks can spread deadly illnesses, such as lyme disease. Arachnids are found throughout the world, from ponds to rainforests to desert to attics. They prefer warmer climates. There are approx 60 000 species, with many more waiting to be discovered. There are 11 orders with living members today:

    Extractions: Just remember.............eight legs is cool !!!!!!!! The Class Arachnida are the most familiar of the Arthropods outside of the ever-present insects, there are over 80,000 named species and they are united by the possession of eight legs, chelicerae and pedipalps, the lack of biting and chewing mouthparts (food is ingested in most cases as a liquid, though some help is often given the food in becoming liquid by the secretion of, or regurgitating onto or into the food of, digestive enzymes from the stomach. The Arachnids, evolved in the sea, but now they are almost entirely terrestrial and have developed several important features to help them survive on the land. These include: a waterproof (waxy) exocuticle, internal fertilisation, malphagian tubules as a metabolic excretory system and internal organs for breathing and gaseous exchange The class Arachnida is extremely diverse in form and in lifestyles and little more can be said that includes them all. This diversity is reflected in the classification scheme shown below. The Class Arachnida is divided into 13 subclasses, (or orders depending on which classification scheme you are following) of which the Araneae (spiders) and the Scorpiones (scorpions) are the best known.

    Extractions: Arachnids are the group of arthropods that include spiders, scorpions, ticks and mites. All arachnids have eight legs. Arachnids evolved about 500 million years ago. That's about 50, 000 times longer than humans have been on earth. Spiders are arachnids. Their bodies are in two parts, the head and the abdomen. They do not have feelers. Most spiders have eight eyes, but some have six, four or two. Many spiders trap their food in webs. Not all spiders make webs. Some are hunters. Some spiders dig homes under the ground. Some spiders can live most of their lives under water in bubble webs. Some spiders have claws at the end of each leg. Spiders live in all sorts of environments. Scorpions and spiders are predators of other insects. Not all scorpions, and very few spiders, are dangerous to man. All scorpions have: a sting, which they use to subdue prey; pincers, which they also use to subdue and to handle prey. There are far more species of ticks and mites than other orders of arachnids. Ticks and mites are mostly parasitic; scorpions and spiders are not. Where can I find out more information about arachnids?

    Extractions: Skip to content Skip to search - Accesskey = s Posted in Ethology Evolutionary Biology Neuroscience by MC on September 28th, 2006 Now it turns out that the creator of the fictional superhero Spiderman when he decided that the character would have the ability to spin webs from his hands: new research, published today in Nature , shows that the Costa Rican zebra tarantula ( Aphonopelma seemanni ) can secrete silk from its feet. Stanislav Gorb and his colleagues diameter and 2.5 cm long. These silk threads, which are secreted from nozzle-like structures on the feet, act to tether the tarantula to the surface, and were secreted when the tarantula started slipping down the glass, preventing them from slipping further. Until now, it was thought that an ancestral arachnid was able to spin silk from its feet, and that, during the course of evolution, this ability was eventually lost in favour of abdominal silk-secreting glands called spinnerets. In the light of this research, another hypothesis presents itself - that the tarantula independently evolved the ability to secrete silk from its feet, as a means of preventing them from falling to their death. Spider silk is a viscous, proteinaceous liquid produced in, and extruded from, the spinneret (left). Most spider species have six spinnerets (although some have four or two), located on the underside of the abdomen at the rear. Each spinneret is multi-pored and can move independently of the others; the muscles responsible for this movement also force the liquid silk to be extruded from the spinneret. Because the liquid is under high pressure as it is extruded, and because the spider pulls on the silk during its extrusion, the liquid solidifies as it is secreted, producing a thread.

    Extractions: Find arachnids information at Animal Diversity Web Arachnida Arachnids are spiders, harvestmen, mites, ticks , and pseudoscorpions . There are hundreds of thousands of species of arachnids, and hundreds of thousands of species of mites alone. Arachnids are found in nearly all land habitats, and there are some in aquatic habitats as well. Most arachnids need liquid food, so they inject digestive chemicals into their prey and suck out the juice. Except for mites (which feed on all kinds of things like fungus, plants, dead animals, bacteria, and other invertebrates), all arachnids are predators on insects and other invertebrates. All arachnids have eight legs and bodies divided into two sections, the cephalothorax and the abdomen. No arachnids have wings, although some spiders can float on the wind using long strands of silk. Many arachnids use silk, either to catch prey or to help them reproduce. Most arachnids have a simple development where babies look like small adults and just get bigger as they grow. But some, especially the mites, go through more substantial changes during growth. Arachnids are part of a larger group called arthropods , which also includes insects, myriapods, and crustaceans. All arthropods have a rigid exoskeleton and legs that are jointed (arthropod means "jointed foot"). In order to grow arthropods must shed their whole exoskeleton at once in a process called molting.
