False-colour light micrograph of the scolex (head) of the adult pork tapeworm,Taenia solium,showing the hooks & 4 suckers with which it attaches itself to the intestinal walls of its host. Humans are the main primary host of this tapeworm,which infects some 4 million people worldwide. Tapeworms absorb their host's digested food directly through their entire surface area; they have no digestive system of their own. The eggs of the tapeworm develop into larvae in domestic pigs (hence the tapeworm's name) & other animals,their secondary hosts. Humans can be secondary as well as primary hosts.
