The anterior portion of any one of the Arachnida and higher Crustacea, consisting of the united head and thorax.
fused head and thorax consisting of 13 segments covered by a hard carapace
a single body segment with the head (ceph) and chest (thorax) areas fused together
This is the forward section of a tarantula that all the legs come out of. It's akin to both the head and thorax on insects, all in one neat package. It has the eyes (all eight of 'em), the chelicerae and fangs, and the tarantula's brain is inside. Also called the "prosoma."
in mites, a body region including both the head and the thorax.
A lobster's head and thorax are fused. This term defines the area including the head and thorax.
head (ceph) and chest (thorax) area

The front body section on spiders, ticks, and crayfish. Instead of three body sections like insects, these animals only have two (cephalothorax and abdomen).
The first of the two main parts of the body of a spider. This part has the chelicerae with fangs attached, the pair of palps and the four pairs of legs attached to it.

The cephalothorax (prosoma) is an anatomical term used in arachnids and malacostracan crustaceans for the first (anterior) major body section. The remainder of the body is the abdomen (opisthosoma), which may also bear lateral appendages as well as the tail, if present. The term "prosoma" can also be applied to the head of insects, but as the two are always exactly synonymous in insects (not true for mesosoma vs. thorax or metasoma vs. abdomen), the simpler term - "head" - is used instead.
