Not a lot is known about the reproduction habits of these deep-sea octopods, but much can be inferred. For example, dissected females were found to have multiple eggs inside their body, but these eggs were all at various stages of development, meaning they probably lay eggs all year long rather than having a specific breeding season. We also know that males have an enlarged segment of one their arms. This arm, like in other species of octopuses, is used to transfer the spermatophore, with is an enclosed packet full of gametes, into the mantle cavity of the female. Once the spermatophore is in place it ruptures, fertilizing the eggs internally. The female then lays the eggs on the underside of rocks and shells and leaves the young to fend for themselves.
While thinking about how I was going to structure this essay, my son was making Ramen noodles. I thought the packet of spices he tore open and poured into the pot was a perfect analogy for the spermatophore. Here is a drawing of this structure. The part labeled "cap" is where the packet is torn open once inside the female’s body.
