I estimated that Male 2 was about 90 cm long but I did not measure him.
Male 2 swam down very quickly and attacked Male 1, returned to the position shown in the photo. He then immediately chased off a cabezon and appeared to then chase off a large copper rockfish. All in about 10 seconds.
I backed off and swam to the South, taking a picture looking North and then looking West. I had not seen the head of the female yet, and was wondering if the fish was dead since there was no movement. I noted Male 2 quivering several times as I was observing female, and he stayed on the North side of the female.
