Raft Spider with Egg Sac Video

I often forget I can record video on my camera, but this raft spider needed to be seen in motion, a still photo just wouldn't have captured the moment.

I shot this on the Coombe Heath pond and thought Michael and Rob would like to see it.

I've used a link as I don't know if I can post video files on this forum.
