coelomate asked you:  Soooooo, for the first time in my life, I am virtually smitten. Your art is wonderful! I don’t know why I love it, just that I do. Keep it up. And, I guess this is for questions, so here goes nothin’: What’s your favourite type of candy?

This is a nice message, thanks for taking the time to write it. As for candy, thats kind of a big question. I have a major sweet tooth. First of all some of these things i mention may not be things outside of australia so just bare that in mind and don’t just think i’m making up exotic sweets. I’m a little bit addicted to starburst rattlesnakes in that i need them all the time to survive. I love gummi bears, nerds are pretty rockin, zappos, fizzers… I also love chocolate but it has to be a pretty specific kind, dark chocolate is OKAY but only a lil bit and I like white chocolate as well. 

I got a taste for both kettle corn and chocolate covered pretzels when I was in America but neither of those things exist here, so I have a fairly constant yearning. I did actually find a shop that sells chocolate covered pretzels here but its kind of expensive in comparison to the giant bags you could get for like 2 dollars in New York.  I kinda went on a bit there… ANYWAYS thanks for the message. Questions: ANSWERED (most certainly.) 

Human embryonic stage 9 occurs during week 3 between 19 to 21 days. The embryo is now 1.5 to 2.5 mm in size and somites have begun to form and number between 1 to 3 somite pairs during this stage.

Ectoderm - Neural plate brain region continues to expand, neural plate begins folding over the notochord. Gastrulation continues through the primitive streak region.

Mesoderm - Paraxial mesoderm segmentation into somites begins (1 - 3 somite pairs). Lateral plate mesoderm begins to vacuolate, dividing it into somatic and splanchnic mesoderm and to later form the intra-embryonic coelom. Prechordal splanchnic mesoderm begins to form the cardiogenic region, from which the primordial heart will develop.

Endoderm - Notochordal plate still visible which will form the notochord. Endoderm is still widely open to the yolk sac and germ cells form part of this layer. Extra-embryonic mesoderm on the yolk sac surface begins to form “blood islands”. 


Saw a much-loved (once a feeder!) goldfish today, presenting for bloating and general lethargy.

Radiographs found a fluid-filled coelom, and sampling of this fluid found it to be clear with no evidence of pathogenic organisms or odd cells.

Differentials for this fish included polycystic kidney disease and neoplasia, among othets. Given its presentation and history, along with disease prevalence, we leaned more towards polycystic kidneys, though we’ll likely never be sure unless he gets a necropsy post-mortem. The owners weren’t interested in an ultrasound.

For now, he’s had much of the fluid drained for comfort and the hope that it’ll help improve his quality of life for as long as possible.

What language does that pronunciation come from?

This sounds suspiciously like you’re challenging me to prove I pronounce my own screen name correctly, but it’s a Latin adaptation of the Greek words words κοῖλ-ος for “hollow” and ἄκανθ-α for “spine”. The name “hollow Spine” refers to the hollow spines of its fins, though some mistakenly believe to refers to the much more remarkable notochord present in the fish’s body, an early stage in vertebrate evolution where the animal has a cartilaginous tube instead of a true back bone (especially interesting in coelacanths because they are an otherwise bony fish)

The word “coelom” itself is fairly commonplace in the field of biology, referring to the main body cavity of multicellular animals. “Coelomate” refers to any animal that possesses this internal cavity, “acoelomates” are creatures with no coelom (such as flatworms). A creature with an open circulatory system where the fluids contained in the coelom supply oxygen to the organs are referred to as having a “hemocoel”. A creature possessing more than one coelom has coelomata.


Green-rumped Parrotlet that presented for lethargy, and aggression toward her mate. A mass was palpated in the coelom so radiographs were taken.

There is medullary hyperostosis in the long bones which means this is a reproductively active female. You can also see a soft tissue mass in the coelom which is pushing the grit filled ventriculus cranially. The mass has some mineralized material within as well.

All of these signs plus the history all point to reproductive tract disease. Likely this is a salpingitis with a retained egg. There is fluid in the coelom also which could be yolk, causing a coelomitis.

Prognosis in these cases is very poor, even with surgery which is the treatment of choice.
