Q

Consider the hypothetical animal, which we will call intropsychipus. The intropsychipus is a very small animal, and cannot move very quickly. It’s natural predator is very slow as well, and so the intropsychipus needs to know the predator is there, but it never needs to mount a rapid escape. What might its eyes be? (Select all that apply)
A) should be relatively small
B) should be relatively large
C) should contain a simple lens
D) should be a light sensitive patch or curved cup
E) intropsychipus doesn’t need eyes

A

A) and D)
