Big Eyes

Our Cornell Biology Service Leaders, Jane and Iman, visited Ms. Anderson's class at BOCES today, and checked in with students raising brown trout.  The students went through feeding and water quality testing practices, and discussed options to resolve a high nitrite level in the water, which is potentially dangerous for the young trout. 
We have time for a little up-close observation, also.  Here, you can see the external structure of the eyes on these 6 week old browns.  Notice how the lens of the eyes are round, and extend away from the body on each side of the head.  What type of adaptation might this be?
