Blueberry: I can’t believe how hard they’re working us these days

Apple: oh my god yeah we’re so understaffed it’s ridiculous

Pear: At least we have Banana and Orange working today

Strawberry: ooh guys I have some really bad news

Pear: oh no what is it…

Strawberry:

I'm a sad person not because anything is wrong. but because as a child I saw an alligator gar at the aquarium and experienced a joy so profound it permanently blew out my dopamine receptors and I've been incapable of happiness since

The final stage of every OC's creation is having to go through websites like this to name it:

Why are rain frogs so round? What's /inside/ of them around such an itty bitty skeleton?

So it turns out this is a really interesting question.

The first thing we must be aware of is that rainfrogs as we see them in videos of them squeaking are not quite the same shape as they are when at rest:

But you are quite right, they are very round. This is exemplified by the skeletal photo you refer to:

So what are we seeing?

Well, firstly, note that the body cavity in these frogs actually envelops the femurs, such that only the tibiofibula (fused in frogs) and the tarsals and metatarsals are outside the body. The arms are quite similarly enveloped, but a bit of the humerus does extend outside the body cavity too. This predisposes them to a rounder body shape.

Next, note the ilia - the U-shaped bone in the pelvic region. These in some breviceptid frogs are synostotically fused with the sacrum - that is to say, they are bound by bone-based connections to the bow-shaped vertebra at their tips. This whole joint seems to be quite smooth, and as a consequence, the back of the frog is quite smooth. The other thing we can see here is that the urostyle (i.e. the frog version of a coccyx) juts quite far beyond the ischium and pubis. This extends the body cavity beyond the hips. Note also that the pelvic girdle seems to be largely below the spine, rather than the typical position for frogs behind it and continuous with it. This makes the legs sit below the spine, rather than at its end, enhnacing the vertical roundness of the animal.

Next, let’s talk some soft tissue. Now, I’m not as familiar with soft-tissue in frogs as I am their skeletons, so you’ll have to bear with me a bit (rawr). Beddard (1908!!) studied the soft tissue of Breviceps verrucosus Rapp 1842. It seems that the majority of the body of these frogs is actually muscle. Beddard noted that muscles join the leg at the knee that extend into the body cavity, such that the inclusion of the thigh in the body cavity is further accentuated by musculature. The rectus abdominalis muscle is unusually large, extending from the lower abdomen up and around the sides of the body. Indeed, this large size appears to be the pattern with all of the major muscles, though in the throat the typical arrangement of large and small muscles is somewhat reversed. On the lateral side of the head, there is a substance that is not muscle, but appears to be loose tissue in which sits what is apparently the thymus gland.

There is a very large gap between the end of the urostyle and the anus (one fifth of the total length of the frog), in which there are almost no muscles, save for the one surrounding the lower cloaca. On either side of this area, between the posterior-most muscles of the thigh, lie two large ‘lymph-hearts’, as described by Beddard. These are between one quarter and one third of the total length of the frog. A further lypmh-sac sits between these lymph-hearts and the skin of the femoral region, and they are thus probably analogous to the femoral lymph-sacs of other frogs.

I find it interesting that Beddard (1908) did not mention any glandular formations in the dorsal region. As is evidence from many images (see below), these frogs are able to secrete a white, sticky, noxious substance from their skin (which they actually have to use during amplexus, as the male is too small relative to the female to mount her properly, and so he sticks himself to her with his glandular glue… kinky).

These glands do not apparently take up a great deal of the cutaneous tissue, and so I suppose are of no consequence to the size of the frog, especially relative to its enormous muscles.

The diet of these frogs consists almost exclusively of hymenopterans and isopterans (ants and termites). Neither of these insect groups are particularly fatty, so it is little surprise that their bodies appear to contain no large fat deposits - fatty bodies extend from the gonads up to the lungs and heart, but these comprise only a tiny fraction of the frog’s mass, and don’t contribute to the round shape. Instead, their bodies are extremely muscular, allowing them to be adept burrowers, ideal for their fossorial lifestyle.

So TL;DR: rain frogs are little balls of muscle (maybe the largest muscle mass relative to body mass of any vertebrate? science just doesn’t know).

Thoughts that are mutual between cats and their people:

Yeah you're cute when you sleep but you didn't let me sleep either so I'm going to annoy you now because I'm bored. Hahah get poked, sleepy idiot.

How do you not comprehend this when I am literally staring at you. Like I understand that your brain can't understand things this nuanced but come on, how do you not get this.

I don't know if you know that what I am currently doing is an expression of affection, but that won't stop me. Knowing that I showed you that I love you is enough.

I heard a crinkly material and the sound of you chewing so I have to know what's in your mouth RIGHT FUCKING NOW.

I can't communicate with you and you can't communicate with me, so I'm just copying the tone of the sound you're making in hopes that you understand that I try.

You are doing activities beyond my comprehension, and I find this fascinating. I will never understand what the fuck you are trying to achieve here, but I am intrigued nonetheless.

Hey are you ok, you haven't done your weird thing in a while. Yeah I don't get why you do that but I know you do that when you're ok.

A perfect newborn leafcutter ant was recently born at a zoo but nobody cared because it wasn't a piece of shit hippo

ill figure it out <- common utterance of a girl who is completely fucked

spn is for those of us who never learnt how to move on from anything ever 🫶
