Cephalothorax
(redirected from cephalothoraces)

    Also found in: Dictionary/thesaurus, Wikipedia 0.03 sec.
cephalothorax [¦sef·ə·lə′thȯr‚aks]
(invertebrate zoology)
The body division comprising the united head and thorax of arachnids and higher crustaceans.
Cephalothorax 

that part of the body of arthropods formed as a result of the fusion of the cephalic and thoracic segments.

The cephalothorax is characteristic of higher crustaceans and chelicerate arthropods (Arachnida, Xiphosura, and the extinct paleozoic Eurypteridae). Among the crustaceans, the cephalothorax is formed in Decapoda by the fusion of six cephalic and seven thoracic segments. In Chelicerata it consists of the six front segments of the body (which usually bear the appendages), to which a seventh (pregenital) segment is sometimes attached.
