Ah, the juvenile green frogfish.....The part used in the video is the best part of the entire clip, but the original clip total is about 1 minute long.

The thing was really tiny, maybe 30 mm long, and really didn't want anything to do with me. I sometimes try to reposition some subjects under the right conditions, but this juvenile frogfish was clearly in a defensive flight mode, and I didn't want to stress it, so often times the shot angle wasn't the best.

It was hilarious watching it propel itself by expelling water out of its gills.
