CreatureCast - Rhizocephala - a charmingly animated look at the lifecycle of rhizocephalan barnacles, one of the more horrifying (non-charming) parasitic crustaceans (likewise). NOT a practitioner of parasitic castration but still disturbing: The bobbit worm. Happy swimming!

It's really not a bad article, especially if you are familiar with angler fish.

The video of the bobbit worm is amazing and terrifying in a way that I didn't expect. I generally am not bothered or alarmed by this type of thing, and the beginning of the video lulled me into thinking that I knew what I was going to see. I was wrong.

Also, the Wikipedia page on barnacles introduced me to an intriguing new word: spermcasting.

You've help my weight loss diet by helping me completely lose the desire to eat. Thanks.

The first one is cool. Parasitic species can undergo really astounding simplification. Tapeworms don't have digestive systems. These barnacles are basically a disembodied mycorrhyzal network.

As for the Bobbit worm, it's a predatory aquatic polychaete. I mean, this is what polychaetes do. Earthworms are the exception, not the rule. They are the meek, dirt-eating losers of the annelid phylum.

Glad to see the infamous tongue biter in the parasitic crustacean link. Now excuse me while I go rub my skin down with a cheese-grater, maybe that will stop the itching.

This is absolutely fascinating! Thank you for posting this.

I love the fact that the Bobbit worm is so freaky looking but also kinda pretty. It's sitting on the ocean floor, waiting for food, displaying its pretty sparkles for all to see. And then BAM! You're dragged into its underwater lair. Also, it pleases me a little too much that Rhizocephala have a parasite of their own.

And they have their own little parasites to bite 'em.
And so on, ad infinitum.

It looks like the octopus gets away in the bobbit worm video. I was so relieved! That's one lucky/badass octopus.

It's parasites all the way down.

"It looks like the octopus gets away in the bobbit worm video. I was so relieved! That's one lucky/badass octopus."

It doesn't just get away, after it's snatched down into the worm's underground lair and seemingly vanished into thin air water, it suddenly makes a triumphant return aboveground, having fought valiantly and escaped from within the belly of the beast.
