In fact, as I described here, the life cycle of tapeworms was discovered by a particularly devout nineteenth-century parasitologist who wanted to demonstrate that God made nothing in vain.

Not only do tapeworms live in a huge range of animal hosts, but the life cycle of a single species may take it through several different species–a shrimp, a fish, a sea bird, and back to the ...

Life cycle of blue-crab parasite unraveled Date: October 4, 2012 Source: Virginia Institute of Marine Science Summary: Biologists have succeeded in their 15-year effort to unravel the life history ...

Head lice have a three-stage life cycle. They begin as nits, hatch and become nymphs, and become full-sized adults within weeks. Read more about them here.

When infected pork is eaten by a human, these muscle cysts come to life in the person’s gut, growing into an adult tapeworm, shedding eggs, and beginning the cycle anew.
