Salamander speed

[Kent]

I noticed when I saw salamanders in North Carolina, they moved extremely quickly, but I see videos of Ambystomatids and Salamandra and they move relatively slowly. I'm not exactly sure what my question is, I guess it would be why? Is it because of size? Just curious.

I think a lot of it has to do with habitat type and prey items.

Species like some Desmognathus live in wet, slippery habitats, making them able to move faster (less friction). They also have quickly-moving prey (bugs, fish, other salamanders, etc.).

Ambystomatids spend all their time under ground, waiting for a worm to crawl by. No need to be speedy!

I think the fact that many of the NC salamanders are also quite small. They have to be quick to avoid being eaten.

Thanks very much!
