Vegetables That Eat You

Well.... if you are only a few millimeters long.

The bladderworts (Utricularia radiata) are starting to bloom in Chase Pond.  These plants have small yellow flowers that float just above the water.






 They are pretty, but they aren't the most interesting thing about these plants.  The fun part is below the water.  Each bladderwort leaf is covered with little ... yep, bladders.  These small balloons have the water sucked out of them by the plant leaving a partial vacuum.



 When small aquatic crustaceans bump up against small hairs on a bladder it pops open and sucks in water and the crustacean.

Then the bladder closes up and digests the prey.


Yum.
