Instead we ran into opalescent squid in the process of laying eggs and creating a new cluster! It was amazing to watch and I got some footage of the event. If you look closely in the first shot, you can see the female has an egg sack in her arms and is laying eggs into it. The rest of the shots are individuals carrying the egg sacks and attaching it to a cluster.
This was shot with a Canon 5D MKIII, 100mm f/2.8 macro in an Aquatica housing with a pair of Sola 4000s.
