The slender, elongated body of tibellus maritimus is highly adapted for stealth and speed, an embodiment of efficiency in its coastal grassland habitat. This adept hunter cleverly camouflages itself amid foliage, employing remarkable bursts of speed to capture prey, typically smaller insects, in a strategy that does not rely on webs, unlike many of its relatives.

The prosoma often has a broad bright median band, which is plain. The legs are yellowish grey or brown with dark spots. The opisthosoma is very variably coloured, brown or yellowish brown, mostly spotted with bright median band and often with a dark cardiac mark that reaches the second pair of sigillae, and with dark chevrons. The male often more intensely patterned, although sometimes males may be plain dark brown. The body length of a male is 3.5-6.5 mm, that of females 4-8.5 mm.

Philodromus margaritatus is a species of philodromid crab spiders. It is found in New Jersey, Europe, Turkey, Caucasus, Russia to Kazakhstan, Korea and Japan.

Males of this species are approximately 3.5-5.0 mm long, and females are about 5.3 mm long. Body color is variable, mostly in shades of brown or yellow. Spots are also a common body pattern. Males tend to have more spots than females. Legs are usually yellowish brown or grey. Some members of the species also have spots on their legs. Males of the species have a noticeably asymmetric sperm duct. Male pedipalps contain nerve tissue and a sensory organ.

With an innate agility that belies its diminutive form, philodromus fuscomarginatus is well adapted to swiftly navigating the intricate terrains of its habitat, relying on speed rather than web-trapping to capture prey. Sporting a propensity for varied hues that allow for adept camouflage, this arachnid is a master of stealth, often evading detection entirely by both predators and prey. Its life cycle comprises a transformation from a predacious youth, feasting primarily on smaller arthropods, to a mature adept hunter exhibiting finesse and precision.

The running crab spider (Philodromus dispar) hunts small flies, but it doesn't build a web like other spiders. It often searches for its prey near houses. The female spiders lay their eggs into cocoons that are attached to leaves. Then, they guard those eggs until they hatch in the fall.

Adorned with a muted palette that camouflages adeptly amidst foliage, metallic crab spider boasts exceptional agility, which enables it to deftly capture prey by sprinting rather than spinning the intricate webs typical of its order. As an adept hunter, it consumes a varied diet, making it an integral component of its ecosystem by regulating insect populations. During its transformation from juvenile to adult, metallic crab spider exhibits significant morphological changes but retains its distinctive speed and hunting prowess throughout its lifecycle.
