I found about a dozen egg sacks on the inside of the cover of my MJ. They are a little larger than a BB and have some white things eggs in each one and in this one it looks like they are alive and moving. The only opening in the MJ is the two small holes ~1/8â€Â, and the sacks are larger than the holes. Does anyone know what they are?
In the first picture there is a copepod in the upper right to give you an idea of size.
In the second, just below center is what I think is a partially developed snail. It is upright with a black eye and a clear antenna and darker body.
