The Wonders of GoPro 2
This is the footage of mating squid in Curacao last October found as we were returning to shore from an hour long dive. The female stayed close to me the whole time. She was so close sometimes, probably 2-3", that I could not even use the LCD to center her in the frame! The male (turning purple with lust and being "cock blocked") goes in and out of the frame trying to position himself below her so he can insert the sperm packet. You can see them communicating.. the color changes are not from shading and sun variations.
The inobtrusive pocketsize GoPro made this footage possible. MY DSLR rig would have frightened them away I am certain. Unfortunately, the battery died before the !@#shot happened. As I backed away, he positioned himself and completed the deed.
