Arachnids
Arachnid, term for animals in the class including the scorpions, spiders, daddy longlegs, mites, and ticks, and certain other eight-legged land invertebrates.
Arachnids have a pair of tagmata called a prosoma and opisthosoma. The prosoma is partially or completely covered with a carapace-like shield. The opisthosoma may be segmented or unsegmented.

Spiders are predatory invertebrate animals with two body segments, eight legs, no chewing mouth parts and no wings.
Arachnids are a class (Arachnida) of joint-legged invertebrate animals in the subphylum Chelicerata. All arachnids have eight legs, although in some species the front pair may convert to a sensory function.
As arachnids, scorpions have mouthparts called chelicerae, a pair of pedipalps, and four pairs of legs. The pincerlike pedipalps are used primarily for prey capture and defense, but are also covered with various types of sensory hairs.
An arachnid commonly seen at the Zoo, the jumping spider, is also unlike its relatives. Most spiders have poor eyesight. That’s why they use their webs as a sort of net to catch prey.
This arachnid is fairly common and can be found in many cool, moist, wooded areas throughout the world. They are often seen near pools of water because they need to drink constantly.
This arachnid is one of the largest species of scorpion in the world, with adults averaging up to 8 inches in length.
This arachnid lives primarly in Arizona, where it occupies a wide variety of habitats, from sandy deserts to grasslands to mountains.
These arachnids are generally found under logs or burrowing in the sand.

Like all arachnids, the Harvestman has eight legs, or ought to. The legs are easily broken off but as long as it has enough legs to support itself and get around, it can spare a few.
Scorpions are arachnids (not insects) and the scorpion is most closely related to spiders and ticks.

Their diet consists largely of bees, beetles, ants, and arachnids. Other foods include crayfish, sowbugs, grasshoppers, trichopterans, lepidopterans, and dipterans [15,20].
Small insects and arachnids will need to be fed small insects, and as they grow they will require larger prey items.
Abdomen: in arthropods (crustaceans, insects and arachnids) the abdomen is the hind region of the body, which is usually segmented to a degree (but not visibly in most spiders).
: This is one of the world's largest arachnids. The body is made up of the cephalothorax, the abdomen, and eight legs, all of which are covered with long, partially pink or salmon-coloured hairs.
As with other arachnids the goliath has eight legs. These legs are covered in a dark brown hair and at each "joint" they lighten to almost white. The goliath also has two appendages close to their fangs that appear to be legs, but aren't.
In Texas, their seasonal food, as judged from the analyses of 79 viscera, is as follows (expressed in percentages): Fall " insects, 76; arachnids, 24. Winter " insects, 52.3; arachnids, 5.3; reptiles, 1.6; small mammals, 18.
Arthropods make up the largest phylum of animals and include the insects, arachnids, crustaceans, and others. Arthropods are characterized by the possession of a segmented body with appendages on each segment.
Scorpions are members of the class Arachnida and are closely related to spiders, mites, and ticks. They are commonly thought of as desert dwellers, but they also live in Brazilian forests, British Columbia, North Carolina, and even the Himalayas.
The Spider's Silk: As part of the arachnid class spiders have two main body segments: the cephalothorax and abdomen. Their ability to produce silk separates spiders from other arachnids.
Spider - A predatory arachnid that usually has silk-spinning organs at the back end of the body; they spin silk to make cocoons for eggs or traps for prey.
The kowari's diet consists of insects, arachnids, and probably small vertebrates such as birds, rodents, and lizards. It does not need to drink water - it gets all of the moisture it needs from its food.
It is actually a distant relative of crustaceans, and is more closely related to arachnids such as spiders, scorpions and ticks.

Some invertebrates include protozoans, arthropods (insects, arachnids, crustaceans, etc.), worms, jellyfish, sponges, mollusks (like cephalopods [octopus], gastropods, bivalves [clams, oysters, scallops]), and many others.
pedipalps -- The second pair of appendages of cheliceromorphs. In many arachnids, such as spiders, the pedipalps are enlarged in the male and used for copulation.
Diet: The mouse is an omnivore; it will eat almost anything. It eats grain, seeds, grasses, fruit, roots, stems, and small animals like , (and other ), arachnids, etc.

Distribution This tiny arachnid is found in the Edwards Plateau, Travis County, Texas. Other The primary threat to the Tooth Cave spider and other endangered cave invertebrates is the loss of habitat due to urban development.
They eat mollusks, worms, conifer seeds, fungi, insects, and arachnids. Plant material may comprise 60 percent of their diet. The dark gray fur is nearly uniform in color, though the feet are whitish, and the tail is bicolored.
