Can Someone Identify This...

[Roger Southwick]

A bunch of pals and I went to Wazee last Sunday, this time at the Sherwood Forest (north-east) boat launch.  I specifically brought the camera with 100mm macro lens to search for the "egg sacs".  After searching for over an hour in the shallows, I couldn't find any evidence of the sacs.  All the submerged wood in this area is covered by something else (see below), and there are a lot more fish in this area, so maybe it's not a suitable location.

On the second dive we scootered around the lake.  I did spot some egg sacs on the top branches of some trees near the south boat launch, but didn't have the camera with me.

Here are a couple photos of the stuff that covers submerged wood on the Sherwood side.  This is on the platform:

I couldn't see clearly enough with my mask to see if they were moving, but they look like they could be a colonial animal (they look similar to barnacle gills) rather than a plant.  If anyone has a video camera with macro capability, it would be nice to see them in action.
