Colorful bladders:
Back at boat launch
I used my traveling aquarium to take a few images of aquatic Utricularia.
I like the way that Utricularia macrorhiza bladders are often
very colorful. The purplish-red color results from pigmentation produced inside the bladder cell walls, and is not
the result of captured food.
If you prefer a more natural-looking view of these stolons
you can look here.
