Tapeworm. Coloured scanning electron micrograph (SEM) of the head region (scolex) of a parasitic tapeworm,Taenia sp. The scolex has suckers (upper left) and a crown of hooklets (top left) that the worm uses to attach itself to the inside of the intestines of its specific host. Tapeworms have no specialised digestive system but feed on the half-digested food in the intestines by direct absorption through their entire skin surface. Taenia saginata is the most common tapeworm in humans,typically acquired by eating undercooked contaminated beef. Diarrhoea,weight loss and abdominal discomfort may result.
