octopus reproduction


 Octopus eggs hatching 🐙

The male octopus has a modified arm called the hectocotylus, which is about a meter long and holds rows of sperm. Depending on the species, he will either approach a receptive female and insert the arm into her oviduct or take off the arm and give it to her to store in her mantle for later. In the latter scenario, the female keeps the arm until she lays her eggs, at which time she takes the arm out and spreads the sperm over her eggs to fertilize them.

The female meticulously cares for her eggs until they hatch, forgoing food the entire time. She blows currents across the eggs to keep them clean and protects them from predators. The eggs might incubate anywhere from two to 10 months, depending on the species and the water temperature. Once they hatch, they’re on their own – one source cites an estimated 1 percent survival rate for the giant Pacific octopus from hatchling to 10 millimeters. Depending on the species, some octopuses begin life as miniscule specks floating on the ocean’s surface that drift down upon reaching a larger size, while some start out a bit bigger on the ocean’s bottom.

Lately I’ve been seeing and experiencing some confusion on why Hank the septopus’ missing arm hadn’t grown back, since they can fully regenerate in a matter of weeks.

But after doing some research, I learned that a male octopus’ tentacle with reproductive organs is detachable and takes up to a year to regrow.

So Hank didn’t just loose any ol’ tentacle.
He lost THE tentacle.

Decided to spread some octopod knowledge because I think some people were confused. 

So… Right here, doodled a lady octopus with her eggs she’s taking very good care of. After the male and female mate, they both die soon after the eggs hatch. The male doesn’t seem to stick around but the female finds a cave or den like place to lay her eggs, somewhere safe from predators. She then spends the remainder of her life caring for the eggs. She won’t leave the den, constantly cleaning and aerating the eggs till they successfully hatch. Due to her forceful starvation in caring for her offspring, she then dies, leaving the young to fend for themselves in the big ole ocean. 

It’s the females as far as I’ve studied that stay and care for the eggs. I’m more than sure and certain of these facts but if anyone wants to shed some light on this that would be grand!
