This is my favorite underwater picture so far. It shows a bunch of Simuliidae (black fly) larvae clinging to a rock and swinging in the fast current. There are also at least four visible mayfly nymphs, probably in the family Baetidae.  In this picture: True Fly Family Simuliidae (Black Flies) and Mayfly Family Baetidae (Blue-Winged Olives). From Eighteenmile Creek in Wisconsin.

I tried to photograph this salamander but it kept scurrying away from the camera.  The rocks in this little backwater are covered with a thin layer of very easily disturbed silt, so anywhere I followed it I didn't have much time to photograph before the water was too turbid for a good shot.  This is the best I got.  In this picture: Amphibian Order Caudata (Salamanders). From the East Branch of Trout Brook in New York.

Stillborn: In fly fishing, a stillborn insect is one which got stuck in its nymphal or pupal shuck during emergence and floats helplessly on the surface instead of flying away. It is a specific class of cripple, although it is sometimes used interchangeably with that term.
