Strange Adaptations

In this weeks Science Spin we read about a flip-flopping spider.  The spider flip flops when threatened and somersaults to get away from any threat.  Have you ever seen an animal with a weird or strange adaptation?  Maybe a strange bird, bug, or fish.  If you haven't, have you seen any animal learn a strange trick?  Share what animal you've seen with a strange adaptation or trick and tell what it was.
