Re: Do juvenille newts do better in aquatic or terrestrial
What species are you thinking about?
This varies GREATLY among species. Some have juveniles that are completely hydrophobic and won´t touch the water until they are sexually mature, others can be raised aquatically their whole lives without ever leaving the water, and some are somewhere in between.
For those species that accept an aquatic or semi-aquatic life before maturing, most people report that they grow faster and better in the water. However this is probably due to the fact that feeding is easier and the food possibilities wider. Some people argue that raising aquatically a species that normally is terrestrial until adulthood in the wild can have negative effects on their life span or health.
