Perch Spawn

A few more pictures. You can see in some of the still shots if you enlarge them in the background perch that cruised over in a few feet of water when I was taking the pictures. Again assume it's to defend the eggs. Also excuse the last picture of handling the eggs. Posted it because I thought it was a great image. Again if you can enlarge the picture, you can actually see the embryos inside the outer egg sac. That was the first ribbon I came across and wasn't sure what it was, if I knew they were perch eggs would never have handled them. Was only out of the water for a few seconds so don't think there was any harm done, at least I hope there wasn't. Couldn't believe the amount of eggs and perch in this area, was a great sight to see of nature at work.
