The polyphemus moth can be recognized from other Saturniidae by shading changes from pale to dull brown and is in some cases ruddy or grayish. Every one of its wings has a little, scale-less “window” called an eyespot.
The blue catfish is a major river fish, preferring rapids and pools with detectable currents. It also lives in smaller streams that feed into larger rivers, including the Grand, Gasconade and Salt rivers.
The hopping mouse weighs 13 to 26 grams and is 8 to 11 centimeters long, excluding its tail. Its delicate or somewhat coarse fur is three-colored: brown on top from nose to backside; grayish rust on the sides; white underparts.
