Myriapoda is a subphylum of arthropods containing millipedes, centipedes, and others. The group contains over 16,000 species, most of which are terrestrial.[2]Although their name suggests they have myriad (10,000) legs, myriapods range from having up to 750 legs (the millipede Illacme plenipes)[3]to having fewer than ten legs.
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs[1] and are easily recognized by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm / 0.3 in. (Typhlochactas mitchelli) to 23 cm / 9 in. (Heterometrus swammerdami).[2]
The jumping spider family (Salticidae) contains over 600 described genera and more than 5800 described species,[1] making it the largest family of spiders with about 13% of all species.[2] Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungsand tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair being particularly large.

Phidippus princeps is a rare species of jumping spider found in Canada and the United States. These jumping spiders’ vision exceeds by a factor of ten that of dragonflies, which have the best vision among insects.
Platycryptus undatus occurs in North and Central America. The distribution of this species ranges from the Eastern States and adjacent Canada, to Texas and Wisconsin.[1][page needed]Females of this species are between 10 and 13 mm in body length, and males range from 8.5 to 9.5 mm. Like some other species of jumping spider, this species appears to exhibit curiosity towards humans who come into its visual field (jumping spiders all have very good vision.) It favors vertical surfaces such as fences, walls, etc. and because of its habits it is easily seen. It does not frantically flee humans and may be gently “herded” onto a hand, where it may make a thorough exploration and even jump from finger to finger. These spiders are not at all inclined to bite, but even though they are rather small they can deliver a defensive bite if they are pinched or squeezed.
Eggs are laid and hatch during the summer, and adults and other stages overwinter in their individual silken shelters. Although the shelters are built separately and keep the spiders out of direct contact with each other, Kaston reports that as many as fifty of them may crowd their shelters for hibernation together so tightly that they form a continuous blanket under the loose bark of a standing tree.[2]
