Dragon next to her daughter, who I guess I'll call Wyvern to be silly. It seems that of the first batch of babies, only she grew big. But thankfully, there are lots of new babies now. Some of them are Winter's, so I will keep hoping for some to color up as piebalds. Dragon is a very big and beautiful lady!

two completed parts of a bigger commission still in progress! featuring an unspecified agapostemon and oniscus asellus (maple color form)

the agapostemon is unspecified coz i legit just slapped 30 different references of different species together so this is more of a chimera. an Average of the genus than it is a representation of any species in particular

Poddy paradise :)

They be shy. (ignore the armadillidum on underside HE IS NOT SUPPOSED TO BE IN THIS TANK)

W/C Oniscus asellus male with some sort of piebaldism.

No one has been able to successfully pass this trait, suggesting it isn't genetic, but why not give it another try?

Wild type Oniscus asellus, they've been busy eating daisy petals all afternoon 😋

have you ever heard of olms? they’re very interesting creatures and even look a bit like axolotl’s!

they can live a lot longer than axolotl’s and surprisingly aren’t related to them. they are blind and are endangered. It has the longest lifespan of any amphibian, often living to over 70 in zoos, and with a predicted maximum age of over 100. Their reproductive cycle can change depending on their environment, they will lay eggs if it’s warmer and give birth to live young if it’s colder. Olms live in well-oxygenated underground waters with a typical, very stable temperature of 8–11 °C (46–52 °F), infrequently as warm as 14 °C (57 °F). There have also been observations in northeastern Italy where they swim to the surface in springs outside the caves, even in daylight, where they occasionally feed on earthworms. The black olm may occur in surface waters that are somewhat warmer. The olm swims by eel-like twisting of its body, assisted only slightly by its poorly developed legs. It is a predatory animal, feeding on small crustaceans (for example, Troglocaris shrimp, Niphargus, Asellus, and Synurella amphipods, and Oniscus asellus), snails (for example, Belgrandiella), and occasionally insects and insect larvae (for example, Trichoptera, Ephemeroptera, Plecoptera, and Diptera). It does not chew its food, instead swallowing it whole. The olm is resistant to long-term starvation, an adaptation to its underground habitat. It can consume large amounts of food at once, and store nutrients as large deposits of lipids and glycogen in the liver. When food is scarce, it reduces its activity and metabolic rate, and can also reabsorb its own tissues in severe cases. Controlled experiments have shown that an olm can survive up to 10 years without food.

"That is so fascinating!!, I love learning about new sea creatures!!.. and new things!!.. Olms sound so fun to hang around with!.. do you think their favorite games would be sea chess!?.."

"Are you sure, they aren't just a long axolotl?.. they look like one to me!.."

"They're not related to me, Sam!.. but I'm sure it'd be silly if I had a cousin that was a Olm!!.." "I don't get it still.." "This is why I like teaching you about things!!!, you silly sea anemone!!"

I checked on my isopods today. I am always amazed by how big O. asellus are! I have a few adult O. asellus and 2 female T. rathkii in the same tub because there weren't very many, and they are easy for me to tell apart. Well, they both had a million babies, and it turns out that the juveniles are very hard for me to differentiate (i ASSUME there is a mix...). Their colors are very similar and their gills are hard for me to see at this size. The T. rathkii girls keep getting themselves gravid, so I might need to make a small tub just for them so I can easily remove their extra babies. I don't want a colony of that species, the two girls are just my pets lol.

As for the O. asellus, no piebald babies yet, so I assume that means that mama Dragon does not carry the piebald gene. but some of her babies might??? there are some teensy babies that I think are from pied mama Winter, so here's hoping that they are like her!

any way I could get an id on this friendly beast? found em on a water cooler at my work and was very curious as to what exactly it was. the little spots were particularly interesting to me, makes for a very pretty little creature :3

Oniscus asellus, one of the larger temperate zone isopods. they’re recognizable by the white skirt and those charming yellow markings, and if you were to flip it over you’d find no white fill patches on its pleopods.

Starting up an Oniscus asellus culture again and was reminded of an interesting pattern. The lighter color individuals seem to have a higher mortality rate and generally poorer health. Back when I first tried to breed the blonde morph, I never got any babies out of them and they slowly declined until I added them back to the main culture where they all eventually perished. Tonight, one of the lighter individuals I collected perished in the collection cup after a few hours, whereas the rest are fine.

Is it a coincidence or is the color linked to a health issue? If there is a link, why are healthy looking blonde adults such a constant fixture in the wild populations?
