Shrimp. Coloured X-ray of the shrimp Palaemon serratus, in side view. This is a female shrimp carrying eggs under her abdomen (centre left, pink). The shrimp is named serratus for the serrated rostrum over the head (green). The antennae and walking legs are seen at right; shrimps have a single pair of pincers (whereas prawns have two pairs). The X-ray shows the gut coiled within the abdomen (blue), and ending at the tail. Magnification: x0.7 at 6x7cm. x3 at 8x12 ins
