Lamprey gill area. Light micrograph of a transverse section through the gill area of an Entosphenus lamottei lamprey. This fish attaches to other fish using its mouth sucker, feeding on their blood. This means that water cannot go into the mouth and over the gills for respiration, so instead it has lines of seven holes either side of the pharyngeal (throat) area. The seven holes lead to pouches with gills (feathery and orange, left and right). The water is pumped in one side and flows over one set of gills, and then passes to the other set through one-way valves. Magnification: x4 when printed at 10 centimetres tall.
