This is the same brooding female H. lunulata as seen in the previous image. I brought a net near her and she responded with this colorful threat. As she prepares to flee, her grasp on one of her garlands of developing eggs slips a bit exposing them.

A small male O. chierchiae attempts to mate with a female who is blocking the entrance to her cavity using a piece of coral rubble as a door. The male successfully inserted his hectocotylus (third right arm visible at 4 o'clock) through a crack in the door and appeared to pass a spermatophore.

Oc Second Clutch Of Eggs 5 3 2016

While females of most species of octopus are semelparous (reproduce just once), a few are now known to reproduce multiple times (iteroparous). Here is a second clutch of eggs produced by a female O. chierchiae. I posted a photo of her first clutch developing. After they hatched, these were laid.
