Spiders, unlike insects, have only two main body parts instead of three: a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (also called an opisthosoma). The exception to this rule are the assassin spiders in the family Archaeidae , whose cephalothorax is divided into two parts by an elongated "neck".
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 bodies of many arachnids, such as spiders, have two tagmata, as do the bodies of some crustaceans: in both groups the anterior tagma may be called the cephalothorax (meaning head plus chest) or the prosoma or prosome (meaning "fore-part of body"). The posterior tagma may be called the abdomen.
Cephalothorax or prosoma: One of the two main body parts , located towards the anterior end, composed of the head (cephalic region or caput) and the thorax (thoracic region), the two regions being separated by the cervical groove; covered by the carapace and bearing the eyes, legs, pedipalps and mouthparts [3]
The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma (cephalothorax). [1] It is a distinctive feature of the subphylum Chelicerata ( arachnids , horseshoe crabs and others).
