Fish of the Day

Today's fish of the day is the day octopus!

The day octopus, also known as the big blue octopus, and scientific name Octopus cyanea is a well known Indopacific cephalopod. Found in the Indian and Pacific ocean, this octopus can be found as far North as Hawaii to as far South as the Solomon islands, and found from the Hawaiian islands to as far East as the Red Sea and East coast of Africa. These octopi in particular are known for their color changing abilities. The name big blue comes from this color changing ability in fact, as sacs of pigments under the skin can be contracted at will to better match the surrounding environment for camouflage, and courting of mates. This color changing can also be used for communication between octopi, transmitting information of predators and prey nearby.

The diet of the octopus is made up of fish, crabs, and mollusks. This octopus in particular is diurnal, spending its time awake and active during the day, as opposed to the majority of other cephalopods of which are nocturnal. Small prey is eaten immediately when hunting, but larger prey ,such as adult crabs, must be taken back to the den of the octopi. The prey taken to this den are then killed, with crabs being killed with a  single venomous bite, and mollusks being killed by strategic drilling into their shells. These shells and hard carapaces are then discarded around the mouth of the den. These dens are regularly constructed and abandoned, with each octopus spending only around 35 days in each den before moving to find another. This is due to the fact that these octopi are heavily predated on by seals (especially monk seals!), whales, eels, and sharks. To protect from these predators, other than the creation and moving of dens, these octopi have the ability to squirt ink at hunters. Concealing the water so they can get away, along with rare cases of them attacking with their sharp beaks.

Breeding and reproduction can take place year round in the day octopus. Once they reach their sexual maturity, at a size of 8cm, with females larger than males, these octopi will search out another octopus. Males will mate with multiple females at a time, attempting to avoid the females cannibalistic tendencies as long as possible. After the mating however, the sucker on the male octopus begins expanding, continuing to do so as the octopi declines and eventually dies. The female however will survive a few months longer, remaining beside her eggs no matter what. She will slowly die for lack of food and exhaustion as she guards over her eggs until they hatch. These eggs hatch into planktonic larvae, which float in the current unable to swim for the first few weeks of their lives. After that they'll survive anywhere from 12-15 months, able to reach a maximum size of 22cm, and living through only one mating season.

That's the day octopus, everyone! Have a wonderful Wednesday!

YES YES

OCTOPUS

First time I finished a crotchet attempt! Want to shout out my sister who is the only reason I could get through a very confusing octopus making tutorial. Turns out yarn size makes a very noticeable difference.

tbh when it comes to the redesign, if the other ROs can have scars, they ABSOLUTELY have some pretty gnarly scars from miranda.

not even because of her being particularly aggressive either! when she came up to land and began to first realize she can actually get close to people and be affectionate with them for the first time in her life, she had no context on how careful she had to be with landfolk or how rough she couldnt be. adding onto that was that her experience with merfolk were restricted to bellanda too, and she had a habit of just... accidentally grabbing too hard or using her claws or teeth carelessly or just moving without fully checking where everyones limbs are. its just the issue that a playbite for merfolk can be serious lacerations in someone else, and it took... a bit.

which is why now miranda is so constantly careful and hyperaware of how delicately she has to touch everything, because she realized Very Abruptly that she was not like all of her new friends.

(honestly the other ROs who did get bit or clawed are basically over it at this point too. like, it was years ago, and even if they were upset in the moment its hard not to see that miranda clearly didnt want to do that when it happened and has since gotten better about it. hence, why none of them are particularly plussed about when miranda does things that freak other people out, like putting their head in her jaws. yeah yeah, theyve been here, theyve done that, if miranda wanted to hurt them she wouldve done it already, nbd.)

(this is also something that didnt actually happen with the others... scott still can get overexcited and needs to be reminded to pay attention to himself, but also he was already well aware of how to control himself and what was safe by virtue of always having lived around a bunch of different monsters. damien too also figured out pretty early on other peoples limits, as hell is much more open to contacting other people than the merkingdom is. vera had the experience of being raised by the squishier people to begin with.)

It took two months longer than I thought it would cause my hands are super fucked up but i finally finished crocheting the shawl for my sister in law. I just have to weave in all the ends and add the buttons and it'll be good to go
