They spend the earliest months of life as larvae with feathery gills, swimming in the calm water where they hatched. 2011. In their red eft form they can live on land for 3-4 years. The levels of tetrodotoxin and its analogue 6-. The larvae are ½ inch long when they hatch. Evolution in changing environments. Tetrodotoxin levels in eggs of the rough-skin newt. Larvae live in water and use gills to breathe. and Dodson S.I. Gill D.E. These are the “teenage” stage of the Eastern red-spotted newt, a type of salamander with a fascinating life cycle. 2011. 1987.

They lose their gills when they become red efts, but they have to keep their skin moist to survive. Annu. The Eastern Newt (Notophthalmus viridescens (Rafinesque, 1820)), which possesses tetrodotoxin-a toxin for chemical defense, is most vulnerable to predation during its larval stage.
