RE: NANFA-- Fish that slalom, fish that squint

Two interesting stories:

One, on NPR's Morning Edition, explains how fish are able to efficiently
swim at high velocities by zig-zagging between eddies that form around
objects. Go here and click on "The Physics of Fish"

Another, in a recent Journal of Experimental Biology, describes how the
sailfin catfishes are able to reduce the size of their pupils in bright
light - and how it may function not only visually, but as camouflage.
