Off topic, but have some fishes for now

Byzantine history be like:

In 874 Emperor Kostalogous IV ascended to the throne after blinding sixteen nephews, and married his wife, Theodora.

However, he soon ran afoul of the Patriarch of Constantinople, Theopelagionikus, and his wife Theodora.

In 895 he was deposed by his general, Justiniapelomaxorianous II, and his wife Theodora.

This created nine new church schisms.

I love this idea.

Can you render the lyrics of Never Gonna Give You Up?

i’ve gotten this request several times now, so for anyone who asked for this after uniquepickles you can just look at this post.

enjoy!:

letter sequence in this ask matching protein-coding amino acids:

protein guy analysis:

i was really interested to see how this one would turn out, as it is made up almost entirely of repeated domains (the chorus). unfortunately, as many of you may be quick to point out, the chorus of Rick Astley's 'Never Gonna Give You Up' is not in fact a protein domain, and the only thing repeated are some terrible looking loops. i've even included a second picture to properly show you how flat this terrible protein is.

i thought i understood Levinthal's paradox before starting this blog, but these structures are giving me a newfound appreciation. for those who are unaware, Levinthal's paradox is based on the fact that any given protein can fold into an enormous number of possible conformations, but cannot test all of these within the seconds or less that it takes for a protein to fold into its stable tertiary structure. correct folding is controlled by the primary structure (or, the sequence of amino acids encoding the protein) as well as complex factors including the presence of any chaperones to assist with folding, and the relative abundance of the tRNAs matching specific codons for each amino acid. running this blog makes me think of all the ways this process can fail along the way, and all of the almost correct places a protein can get stuck. this one certainly looks like it failed, but even then its hard to believe this is the shape that stuck.

for those interested, the one beta sheet goes with the line 'you wouldn't get this from any other guy', which does only occur once in the song.

Lost Age of Monotremes Revealed by Fossils From 100 Million Years Ago

As bones encased in rock rotted away, water-borne silica seeped into the crevices, solidifying into opal and preserving precious details for

As bones encased in rock rotted away, water-borne silica seeped into the crevices, solidifying into opal and preserving precious details for 100 million years. The resulting fossils now provide evidence that there really may have been an Age of Monotremes, before other mammals came to dominate. "It's like discovering a whole new civilization," says Australian Museum paleontologist Tim Flannery. "Today, Australia is known as a land of marsupials, but discovering these new fossils is the first indication that Australia was previously home to a diversity of monotremes." Only five of these rare mammals still cling to existence: one platypus and four echidna species, shared between Australia and Papua New Guinea. But due to their reptilian-like egg-laying feature, it has long been thought these animals evolved before placental mammals like us and marsupials.

I just discovered the blanket octopus. Would you do a fact on them if not already done? 👀

Sure friend! I am a daily fish fact account only, but I simply couldn't not say something about the magnificent blanket octopus :)

Here is a blanket octopus female! How do I know that? Simple: the males of the species only reach about 2 and a half centimeters, while the females can be as large as two meters long! The species is named after this gorgeous lady's webs that connect to her arms.

"Blanket octopus" refers to four different species actually! And they're all immune to the extremely venomous Portuguese man o' war, young females and males will in fact rip out a dangerous and venomous tentacle from these animals to defend themselves! It is extremely interesting and exciting what kinds of things octopuses are capable of :)

(Sorry to be that guy but) the leaf sheep is not actually a nudibranch, but instead part of the closely related order sacoglossa. Nudibranches are carnivorous while sacoglossa are herbivorous and feed by sucking the sap out of microscopic algae. Many sacoglossa perform a process called kleptoplasty, where they reuse chloroplasts from the algal sap they feed on and implement them into their cells. Some notable examples are the bivalve snails in the family juliidae, the eastern emerald elysia (elysia chlorotica) and obviously the sea sheep. Another slug from the order elysia (elysia rufescens) reuses defensive molecules called kahalalides as well as chloroplasts. Most sacoglossans survive primarily through heterotrophic means (ingesting and digesting) and photosynthesise when food is scarce or unavailable as a last resort. Though research has shown leaf sheep can survive long periods of time with little to no food of heterotrophic or homotrophic (photosynthetic) origin. They store their chloroplasts in cerata, which are structures often found on nudibranches and regularly used for gas exchange or- in blue glaucus’ case- for attack and defence. They also have rhinophores protruding from their face, structures also commonly found on nudibranches, which are chemosensory organs (essentially face tongues) that appear ear like on nudibranches and sacoglossans alike.

To conclude: while leaf sheep are very similar to nudibranches, they belong to the sacoglossan family (which is good because sacoglossans are just as cool) and luckily are not the only animals to photosynthesise.

(I’m researching them for a highschool project and am so obsessed haha)

So not technically a fish but I absolutely love these lil fellas

They’re Nudibranch sea slugs and they all look so pretty!!!!!

Some notable exception are the Sea Bunny (left) which is just the most adorable thing I’ve ever seen

And the Leaf Sheep (right), which is the only animal known to be capable of photosynthesis!

i am SUCH a nudibranch fan oh my god. actual underwater fae creatures. beloved little freak animals. i want to eat them like cereal
