For Cryptobranchidae, do they mean hellbenders or giant salamanders or both?

They probably mean hellbenders, but since the rules never explicitly limit the event to US taxa, I would have info on both.

They state Hellbenders specifically in the list, so i would assume that would be the topic of focus, or else they would put Hellbenders and Giant Salamanders as the common name.

Also, Neoteny vs Paedomorphsis, what is the difference. both seem to be the retention of larval traits in adulthood.

I thought they were different names for the same thing (retention of Juvenile features)?

Neoteny is the slowing of body development with normal sexual development.
Paedogenesis is the acceleration of sexual development with normal body development.
Paedomorphosis is the end effect of both, the retention of larval form by adults.

Yeah, wikipedia seems to be a good source of organized info instead of looking through lab research results and condensing textbooks.

Anyone know how to tell the difference between lacertidae and teiidae? Tips on aneides would be welcome as well.

Ear holes: Cnemidophorus has more circular or D-shaped ear holes, while Lacertidae has oval shaped or slit-like ear holes
Snout: Cnemidophorus has a far pointier and narrow snout than Lacertidae
Coloration: all Lacertidae lizards in the US are alien, and they all have this weird blobby pattern with green or brown accents. So if you see that pattern you automatically now it's a wall lizard.

Edit: Aneides has really big head gland things, and climbing toes.

I also tend to think of Aneides of having a green "snowflake" pattern or the other variety which looks like a flesh colored salamander with giant eyes

What about blind snakes? Their only differences aren’t usually visible to the naked eye and they have many species with similar coloration.
