This isn't really an underwater picture, but a picture taken into my aquarium of midge larvae which lived in the silt I used for substrate. Each larva has a little tower of
detritus (Detritus: Small, loose pieces of decaying organic matter underwater.) built up along the bottom, while the bare larva waves around from the top.
In this picture: True Fly Family Chironomidae (Midges).
This is a pretty clear photo of an
Epeorus nymph clinging flat against a log. The big mound of debris on the bottom center of the picture, attached to the light rock, is a structure that's been puzzling me. I've found several in one section of the river. It's big, like 2 inches long and maybe 1/2-3/4 inch wide/tall, and hollow, like some sort of coccoon or something. It's clearly a structure built by some sort of little creature, but I'm not sure what.
In this picture: Mayfly Genus Epeorus (Little Maryatts).
I spotted this very large leech freely tumbling, and occasionally stopping, along the bottom of a clear, cool trout stream. I paid careful attention later and spotted two more like it, but this one was the largest -- probably over 7 inches stretched out.
There is
one other picture of it.
In this picture: Animal Class Clitellata-Hirudinae (Leeches).Date AddedJul 1, 2006
