Hey Jay good video my friend. These are one of my favs. All my isopods are growing in number and or size. The duckies are doing well and growing. Thanks again Ricky 💃🕺🏼🎶🐈⬛🎸💥
Hey there, the Reddit post you referenced was made by me! Also I am not sure if the ID comes from iNat, I read, that shiro utsuri were selectively bred by a japanese breeder. The original colony is supposed to be N. arcangelii. Where that ID comes from, I don't know. Also worth a mention, on iNat, the user agapakisnikos directly references the paper by Verhoeff for his ID. I am currently trying to get my hands on it, but didn't have much luck until now :)
Thank you for the information. Dr. Keon said that no ones really knows that Verhoeff described in his paper. Him being an authority on Nesodillo thinks that no one can really pinpoint what is archangelii. It’s distinguishing characteristics as compared to other species.
@@isobelcottageexoticstv3233 So he has seen the paper? If so, do you have it by chance? I'd be really interested in seeing it. So in conclusion arcangelii might even be "invalid" because of a insufficient description? But very interesting!
@@amarok1590 yes he has seen the paper described by Verhoeff in 1926. II personally have not seen the paper myself since I am not an academe anymore and no access to old scientific paper. Based on our correspondence I have a feeling that Verhoeff could have inaccurately described the species in 1926 even Schaffus mentioned in his paper im 2003 that some genus has to be reclassified
@@amarok1590 yea without Dr. Keon properly mentioning it. Verhoeff classification could be insufficient to properly identify the species correctly. Anyone who have worked on Invertebrate Taxonony knows that’s is a possibility.
I actually managed to get my handy on the paper today. I spent some time looking at shiros and comparing it with the described characteristics in the paper. So far all characters match, I checked the 7th leg, Telson, uropods, exopods/pleopods, head and antennae. I couldn't check the base of the legs because I couldn't get a good camera angle, but so far I am confident in saying that the arcangelii ID doesn't seem to be far off and is rather plausible. I also took a look at the observation on iNat which you mentioned is C. murina and I have to disagree. The surface of the pereonal segments is too smooth for murina and theres a clearly visible elevation in the middle of the frontal shield which is absent in murina. Also the overall shape looks too wide/flat. If you want to talk outside of this comment section shoot me a message on reddit, I can also send you the paper (it's in german tho) and some of the pics I took of my shiro utsuri :)
@@isobelcottageexoticstv3233 sorry for misusing this comment section, but i gotta store this information now somewhere public. There are issues with the description, probably some of these are what Dr. Kwon was referencing. 1. his description is based on ONE SINGLE female individual, I think i don't have to go into detail why this is bad 2. Missing figures. There are no figures relating N. arcangelii 3. He wrote N. arcangelii are extremely similar to N. schellenbergi. Instead of giving a full description of arcangelii, he just mentiones some differences 4. So we can assume apart from these differences, that we can use the description of schellenbergi (which in turn shares similarities with N. medius, differences mentioned again). HOWEVER a big part of the characteristics for N. schellenbergi are the male exopods. This wouldn't be a problem, if his whole arcangelii description wasn't based on a single female. In contrast, he had about 60 individuals for the description of schellenbergi. I am not sure what he tries to explain with some things he mentions (vague phrasing and no figures) and also I am not sure if some of the things he mentioned are characteristic for the species or maybe just the genus. I would have to look through other Nesodillo species to confirm this, which is quite time consuming I guess. That's about everything I pulled from the paper for now Edit: sadly I don't have the wild type at the moment, but I know someone who has a small group of them, so maybe in the future
@@amarok1590 no worries please use this video to store this information. I appreciate you working to sort this things out. Dr. Keon really did not say straight up what’s wrong with Verhoeff description but I think you are going to the right path
These are one of my favorite isopods that I have yet to acquire and I’m thinking about picking some up from your eBay store I was wondering if you think they could work as a cleanup crew in my dart frog enclosure because they will require a similar humidity level I know a lot of people recommend something cheaper for a clean up crew but that isn’t really something I personally am concerned with would rather have a cool looking clean up crew
They are a bit expensive for a clean up crew. Your dart frog will eat them they are very active. Their population will be decimated they are both nocturnal. I would recommend this as a pet in their own vivarium they won’t disappointed you
Have you thought of having a smaller vivarium for isopods only? I have known some customers of mine who purchased isopods as their pet. This Isopods wont disappoint you they just wont hide all day long they will be out and about I guess - with the dart frog same enclosure that would be a bad idea lol
I love your channel and I keep sharing. I don't understand why more people aren't subscribed!
Thank you so much for all the support 😊

Thank you Ricky!
I hope more people find this video. Really really interesting!
Thank you
Thank you!!
Great video! I just ordered 6 of these cuties. Can’t wait to get them.
Thanks
Great video. Taxonomy matters! Let the world know!
Great content I subbed! Can you please elaborate on light sensitivity?

He thinks start we can’t possibly conclude it’s Nesodillo archangelii accurately

How big are they compared to the Rubber Duckies?
These are a little bigger

What do you feed them?
Dry leaves, decaying woods and sometimes fish pellets

@@isobelcottageexoticstv3233 do they eat squash and cabbage po?
@@ItsAlcs not much I have them cabbage before it’s just molded they like dry leaves and fish pellets (just a pinch)
@@isobelcottageexoticstv3233 Thank you! I got mine recently and have no idea what to feed them. Maybe I'll just focus on giving them leaves
