Slime Molds

If you have never heard of slime molds be prepared for a shock.  Scientist are not quite sure how to classify these things, some put them in with fungi and others classify them a protists.  The really interesting thing about them is that although they function autonomously during certain times, they can "team-up" and form giant blobs that can move like cat sized amoebas.  Pretty cool huh?  For example if a group of them are lining a pipe and conditions aren't good they could team up to form a blob and climb up into your sink.  People have found massive pulsating blobs in their backyard thinking they have discovered an alien or a new species only to be informed it's just slime mold.
