Caption

Coloured scanning electronmicrograph (SEM) of a tapeworm (Eubothrium crassum) head. Tapeworms are parasites that inhabit the intestines of animals and humans. They do not possess a digestive tract and absorb nutrients from digested food of the host through their skin. E. crassum is a widely distributed intestinal parasite of Atlantic salmon (Salmo salar L.), brown trout and sea trout (Salmo trutta). The tapeworm consists of a head (scolex) equipped with grooves (bothria). Although the muscles of the bothria are weak, they are used in attachment to the intestinal wall of the host. The scolex and neck region are connected to the body (strobila) which consists of a variable number of segments or proglottids, which become progressively more mature towards the distal end of the parasite. Mature proglottids containing large numbers of eggs frequently break off and pass out through the intestinal tract of the host. Magnification: x85 when printed at 10cm wide.
