Crayfish Dissection Diagram
As shown in the diagram below, the crayfish body is divided into two main parts: cephalothorax; abdomen; The cephalothorax consists of the cephalic (or head region) and the thoracic region. The rostrum is the most anterior part of the cephalic region of the cephalothorax and will form what is commonly known as the "brow ridge". The part of the exoskeleton that covers the cephalothorax is.

Arachnids breathe via book lungs. More information on arachnids will follow in a subsequent lab. Subphylum Crustacea ( crusta = crust, rind) includes crayfish and lobsters, crabs, pillbugs, and several other groups. They have gills, thus terrestrial pillbugs need to maintain a 100% humidity environment around their gills to be able to "breathe."

The Anatomy of a Crayfish. Let's take a closer look at the anatomy of a crayfish. These creatures have a segmented body that is divided into two main regions: the cephalothorax and the abdomen. The cephalothorax contains the head, which includes the eyes, antennae, and mouthparts, as well as the thorax, which houses the walking legs and small.
