Euw! Ed Yong has a gross-yet-cool post about parasitic nematodes that infect and kill caterpillars - and bring along luminous bacteria whose red glow is unpalatable to birds. If a bird eats the caterpillar host, the parasitic worms die. But the bacterial warning glow protects the worms' immobilized corpse home until they mature and burst out of the dead caterpillar - as grossly as possible, of course. (See photo on Ed's blog).
Natural, uber-gross bioephemera! Thanks, Ed. :)

You may have noticed that ScienceBlogs has gotten a little... strange today. That's because it's ZOMBIE DAY! There are a ton of posts around the site about the various biological, philosophical,…
Ah, the parasitic flatworms called trematodes. There's a lot of them, and many have very strange and impressive life cycles involving many specific hosts. Just about any of them is sci-fi worthy, but this one, in particular, is a real eye-catcher.
Meet Leucochloridium paradoxum, also known as the…
Few humans have been as successful in Hollywood as parasitoids. Parasitoids are a particularly gruesome kind of parasite that invariably kills its host by the time it becomes an adult and is ready to leave the host's body. A parasitoid female wasp, to give one example, will fly along until it finds…
