Speaking of parasitism

In my previous post, I made a brief reference to a parasitic relationship. There are some really amazing, or perhaps strange, such. Here's a YouTube video, of a parasitized snail. The video is about 90 seconds in length. The parasite has changed the behavior of the snail, to the detriment of the host, but to the advantage of the parasite.

Note that if a parasite is too harmful, it will destroy it's own ecological niche -- parasites need hosts.

Thanks for reading.
