There are no known really neotenic frogs.
Some cases of long last Xenopus ta^poles have been reported but none have been able to breed. http://jeb.biologists.org/content/jexbio/207/12/2133.full.pdf
Nevertheless, the whole family Pipidae (Pipa, Xenopus, Hymenochaerus) is considered as pedomorphic (no eyelids, lateral line present) : they undergo un uncomplete metamorphosis.
Anyway, notice most male anurans need their fore limbs to be able to breed.
The nature of frog reproductive cycles makes it very difficult to be neotenic, however, several species of Sphaenorhynchus treefrogs reach sexual maturity while they still have tails and have not completed metamorphosis. In theory, a frog could reach maturity and never lose the tail, which would make for an interesting 'new' sort of creature.
Cool thanks I will possibly do an experiment to see what the conditions make a frog stay with larval characteristics for the longest amount of time then try to see if I can improve those conditions to make them retain the tail
Hey y'all, recently my juvenile axolotl's tail has been floating and can swim down but his tail lifts to an angle and I believe that it is stressing him out. He gets in between his plants to balance himself and I am cleaning out the bottom of the tank with my baster. I believe I overfed him and he also may have eaten many air bubbles. He's been like this for nearly 1 1/2 days.
hello, I am currently tubbing my axolotl due to cycling the tank. I have read different answers on how many times to do a 100% water change a day when tubbing. Some say once and some say twice. I just want to actually ask and get answers for myself. Thank
As often as you need to keep the water clean! Since you´re cycling, I assume you have a test kit. Just test a few times to see how long it takes for your ammonia to go up, and as soon as it does, change the water.
Hi does anyone know if jungle fungus clear is safe to use for my axolotl? She has some either fungus or bacterial growth on her fillibrae and maybe body and I read that's good to use if you aren't sure if the problem is bacterial or fungal
