A tapeworm living inside a bear can reach lengths of 30 feet or more. Sometimes the bear defecates either a living or dead tapeworm. This appears to be uncomfortable for the bear, as you might well imagine.
Not for the faint-of-heart. One minute run-time.
The Guardian goes on to recount a pretty horrifying story where a man believes his intestines are falling out of him, which ruins his morning. He gives it a closer look. And then, like something out of Aliens, the “intestine” starts moving about of its own accord.
It turns out, this guy enjoyed a daily treat of salmon sashimi. And the popularity of sushi is increasing the cases of human tapeworms.
I think the ERJ family will skip sushimi this Lent.
As much as we might not like this fact, parasites are a part of the earth’s biodiversity. If you can get by the gross factor, the evolution of these creatures is fascinating. And it’s not going away. An estimated 40 percent of animals are parasites.
And I believe that estimate of 40%is low if you look at legacy, "Blue", US cities.
