TODAY'S FACT IS

Did you know that the Beef Tapeworm (Taenia Saginata) is the largest member of its genus? Typically, they measure from 4m-10m long (already quite the variance), but they have been recorded as long as 22m.

Like other tapeworms, they do not have a digestive system. They have a living sheath around their body called a tegument that they use to suction themselves onto their host's digestive tract, absorbing the nutrients that the host should be getting. The distinguishing factor for this worm compared to others (aside from its size) is that the anchoring end of the tegument called the scolex does not have hooks, only suction cups.

Uncharismatic Fact of the Day

Tapeworms can be found in the digestive system of many animals, but ironically they don’t have a mouth at all! They absorb nutrients through a thick cuticle that runs along the length of the body; because of this, tapeworms also lack a digestive system and a circulatory system.

TODAY'S FACT IS

Did you know that the Pork Tapeworm (Taenia solium) is a tapeworm commonly found everywhere in the world that pork is eaten? The immature worms develop in the pigs that eat the worm's eggs. Eventually the worms develop into infective cysts in the pig's meat. When we eat the undercooked (or not cooked at all) meat, the cyst develops into the adult worm. Because the worm latches itself into the small intestine, it can easily drop its eggs into the feces of its host, allowing it to spread. Typically these worms reach lengths of 2-3m long, but they have been recorded at lengths above 8m.
