Oh man this is popping off now

Unfortunately the cards are sold out but the memes are here to stay <3

Idk about y’all but valentines memes have been my favorite part of the holiday since I was an inappropriately young child on the internet

So I made some cephalopod themed ones for your enjoyment <3

These puns are ones that did not make the cut for our actual Valentine’s Day cards shown in the last image

Purchase them at squidfacts.bigcartel.com <3

Sarah I want you to know that I work at a zoo so I got 40 squid Valentines for my entire department. These are going to be a hit I know it

Omg I love this so much.

Everybody else, there's still about a week left to get these before Valentines Day. Get 'em at Squidfacts.bigcartel.com

Do you like Squid Facts? 🔲Yes 🔲No

This valentines day, we thought you might need a little help from cephalopods to celebrate. Get a pack of 20 cards for your classroom, your coworkers, your neighborhood, frankly anyone who needs both a valentine AND a little bit of science to boot.

Get 'em here: https://squidfacts.bigcartel.com/

Proceeds benefit science education nonprofit Skype a Scientist AND the graduate student who designed these cards who is studying octopuses (Meg Mindlin @invertebabe!). Meg is trying to afford to get to a cephalopod neuroscience conference later this year and these cards will help her get there 🫡

They, of course, come with the classic heart stickers, a range of shades of pink and purple included.

Im that graduate student and designed these! Buy them because they’re adorable and support scientists

A win win if you ask me

If you asked me as a kid what my favorite animal was, there's a good chance I'd respond "chambered nautilus", though I probably would mispronounce it. I don't know if it's still my favorite but it's definitely up there in the pantheon of weird critters. For this Wet Beast Wednesday, I'll discuss my childhood favorite.

(image: a nautilus)

The nautilus is a cephalopod that lives in a curved shell and looks similar to (but is not closely related to) the extinct ammonites. There are 6 living species in two genera, but 90% of the time when someone is discussing nautiluses they are referring to the most well-known species: Nautilus pompilius or the chambered nautilus. Nautiloids are ancient, going back to at least the late triassic with their more primitive ancestors going back as far as the ordovician period, a time when only invertebrates and primitive plants occupied the land and true fish had not yet appeared. Because of their ancient history, nautiluses are sometimes considered living fossils. I have ranted before on how misleading the term "living fossil" is so I'll spare you that for now. Nautiloids are considered a sister group to the celoids, which contains all the squid, octopus, cuttlefish, and everything else we thinks of as cephalopods. Nautiluses should not be confused with paper nautiluses. Also called argonauts, paper nautiluses are a group of octopi that make an egg case which looks like a shell.

(image: a nautilus)

The most noticeable feature of a nautilus is its shell. The shell is smooth and finely curving, naturally growing in the shape of a logarithmic spiral (though not, as is commonly stated, a golden ratio spiral). The shell has a stripy outer layer and an inner layer coated with nacre. Internally, the shell is divided into camarae (chambers) separated from each other by walls called septa. Each septum has a small hole in it through which a strand of tissue called the siphuncle passes. Most of the nautilus's body is in the foremost and largest chamber. The shell grows new septa as the animal grows, with the nautilus's body moving to a new chamber as it becomes too large for previous ones. Juveniles are typically born with 4 septa, with adults having as many as 30. In addition to providing protection from predators, the shell is also key for regulating buoyancy. The septa can contain pressurized gas or water and the siphuncle regulates their contents by either adding or removing water to increase or decrease buoyancy. Because of its pressurized contents, the shell can only withstand pressure at depths up to 800 M (2,400 ft) before imploding. Oddly enough, nautiluses can be safely brought up from deep waters where most animals would be killed by the pressure changes. To move, the nautilus pulls water into the first chamber of the shell using its hyponome (siphon) and shoots it back out. The chambered nautilus is the largest species, with a maximum shell diameter of 25 cm (10 in), though most get no larger than 20 cm (8 in).

Where celoid cephalopods have tentacles, nautiluses instead have numerous cirri. Unlike tentacles, cirri are less muscular, are not elastic, and have no suckers. They are used to grab objects using their ridged surfaces and can hold in so hard that trying to take an object away from a nautilus can rip off its cirri, which will remain firmly attached. In addition, the nautilus has modified cirri that serve as olfactory receptors and a pair that serve to open and close the shell when the nautilus needs to retract into it or emerge. Nestled within the cirri is the beak, which is used to consume the nautilus's primary prey of invertebrates, though they have also been seen scavenging fish. Their eyes are less developed than most cephalopods, lacking a lens and consisting of a small pinhole that only allows the nautilus to see simple imagery. Their brains are differently structured than most cephalopods and studies have found them to have considerably shorter long-term memories.

Cephalopod reproduction is quite different than that of other cephalopods. While most cephalopods are short-lived and semelparous (reproducing only once), nautiluses can live over 20 years and reproduce multiple times (iteroparity). They do not reach sexual maturity until around 15 years old, with females laying eggs once per year. Eggs are attached to rocks and take 8 to 12 months to hatch. Males have a structure called the spadix composed of 4 fused cirri that they use to transfer sperm to females. Females lose their gonads after laying their eggs and will regenerate them for the next year's mating season. Interestingly, male nautiluses seem to vastly outnumber the females.

Nautiluses are found in the Indo-Pacific reagion of the ocean and can be found on the steep slopes of coral reefs. They prefer to inhabit waters several hundred meters down. It was once believed that they would rise to shallow waters at night to feed, lay eggs, and mate, but their vertical migration behavior has since been shown to be more complex than that. They have noon been fished by humans for their shells, which have become popular subjects in art and can be made into a number of decorative pieces. The nacre of the shell can be polished into osmeña pearl, which can be quite valuable. Demand for the shells combined with the late sexual maturity and low fecundity is threatening all the species. As of 2016, nautiluses have been added to the CITES Appendix II, making them protected by limiting international trade of their shells. Despite this, they are still threatened and require further protection

#okay but they also mate for 30 hours #it’s literally so freak and wild #I feel like this is an important note about their reproduction #who the fuck mates for 30 hours #that’s exhausting

The Sea Creature of the Day is the Gulper Eel/Pelican Eel!

i keep forgetting to do this until im half asleep each night so this one is going to be a shorter one

i love deep sea creatures that just have the adaptation of more mouth 🥰 among those, the gulper eel is by far the most simultaneously horrifying and adorable and i love them a lot

every time they eat something i like to imagine them making a lil "nom" noise

[invertebabe]

sea creature of the day is the wolf eel i love these silly fellas!!! they are very beautiful to me
