Defying Trophic Levels



Urchin eating baby cormorant bird.
You might have gotten this email too, but just in case I wanted to share this strange phenomenon.  In ecology we often look at a fixed trophic structure or even a complicated food web.  I think this proves that the food web is more dynamic than we realize.  Urchins have a pretty adaptable diet. Maybe birds are not a preference, but I'm sure this meal was nutritious!  (It still gives me the creeps though.)

 Check out the article for video proof:
