After hearing about these explosive market squid mating events for a few years, I was finally able to see it in person and capture a few images in the process. These short-lived mollusks go out with a bang. After amassing in shallow waters to mate, they deposit their egg capsules (each containing up to 200 eggs) into massive blankets of white, and die shortly after.
Some things I found interesting:
Totally worth the hours of traffic on the 405 and a late nights washing gear after midnight.
References if you are into those type of things :)
