Ribs?

[clay]

do axies have ribs because it looks like they do along der side but is it ribs or just wrinkles ?

 

[joan]

Those are called costal ridges. All ambystomatid salamanders have them. They're basically just folds in the skin.

I think they are a bit like the lateral line on a fish and that they use them to sense vibrations.

 

[joan]

No. Axolotls have a lateral line-esque system, but it is in no way associated with their costal ridges.
