Basic characteristics of arachnids include four pairs of legs (1) and a body divided into two segments: the cephalothorax (2) and the abdomen (3). The ventral side of a brown widow spider. The epigastric plates and furrow are visible, as well as the hourglass marking on the underside of the abdomen, which is a characteristic feature of widow ...
The spider's body is divided into two main parts: a rectangular, slightly rounded cephalothorax and larger ovoid abdomen that is narrower to the rear. [14] The male has a carapace , the hard upper part of the cephalothorax, [ 15 ] that is between 1.9 and 2.3 mm (0.07 and 0.09 in) long and 1.5 and 1.8 mm (0.06 and 0.07 in) wide.
Pachyballus miniscutulus is a species of jumping spider that is native to Ivory Coast and South Africa. It lives in open grassland and in vegetation near to streams. A very small spider, it has a cephalothorax that is ranges from 1 to 1.3 mm long and an abdomen that is between 1.7 and 1.9 mm long.
The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind. [1] The terms prosoma and opisthosoma are equivalent to cephalothorax and abdomen in some groups.
The adult female triangulate cobweb spider is 3 to 6 mm long (1/8 to 1/4 inch), with a brownish-orange cephalothorax and spindly, yellowish legs, and tiny hairs. The round, bulbous abdomen is creamy in color, with parallel purply-brown zigzag lines running front to back.
Herennia multipuncta, commonly known as the spotted coin spider, [1] is a species of spider in the family Nephilidae native to Asia. [2] It exhibits sexual dimorphism, the female being much larger than the male. It weaves a small web on the trunk of a tree or the wall of a building and is well camouflaged by its dappled colouration.
Usually the cephalothorax is somewhat less obviously hairy. The abdomen is evenly rounded without conspicuous sculpting, and in many species is elongated into an olive shape twice as long as the cephalothorax , giving the spider a vaguely torpedo-shaped appearance.
Salticids hunt diurnally as a rule, which is consistent with their highly developed visual system. When it detects potential prey, a jumping spider typically begins orienting itself by swiveling its cephalothorax to bring the anterior median eyes to bear. It then moves its abdomen into line with its cephalothorax. After that, it might spend ...
