Animal-eating Plants!

During a trip to Pokagon State Park (Indiana), I learned about a carnivorous plant called Common Bladderwort.  It's a small, innocent-looking plant that you could easily miss. 

Apparently, the deadly part is underwater -- "little bags" or bladders that trap aquatic organism. Tiny swimming animals touch trigger hairs around the mouth of a bladder. A trap door opens and the bladder expands, sucking the prey inside. 

Common Bladderwort is found in bogs and marshes throughout North America, so watch out!
