are they scent or sight driven? other aquatic pets ive had always seemed to KNOW when food has hit the surface of the water.

Dani, it's a bit of both.

Anyway, I'll be moving this post soon to the General Discussion section in a couple of days, so look for it there when you don't see it here http://www.caudata.org/forum/clipart/wink.gif

There is a nice, brief (if slightly old) review of this in Duellman and Trueb's "Biology of Amphibians". Duellman and Trueb, by the way, is a must-have reference for anyone who wants a detailed, broad reference on the general biology of amphibians.

One of the interesting things that they note is that both visual and chemical cues are used in aquatic foraging. Two studies found prey capture effeciency was highest when aquatic salamanders had both visual and chemical cues available for detecting and capturing prey.

With Tylototriton verrucosus I have the impression that the animals react more on movement/sight by day and more on sent during the night. By day they leave the dead prey lying , by night .. it disappears.
