Ontario Nature. Scientists have suggested several explanations for the unusual life cycle of newts. Adult Eastern Newts retain the ability to survive on land. Eggs are fertilized in spring, and hatch several weeks later into aquatic, gilled larvae, which develop for about three months. Unlike most other local amphibians which have aquatic larvae and terrestrial adults, Eastern Newts have three life stages: aquatic larvae, terrestrial juveniles (red efts), and aquatic adults (although newts in some populations can skip the eft stage). Their menu includes mites, fly larvae, worms, land snails, and slugs. Red Eft activity is also affected by temperature. Be Her Village. 275-278, Plates 26, 27, 29, 30. William R.

The aquatic larvae transform into a bright red juvenile, then spend several years on land as an eft (up to seven years! After a period of rapid growth, the resultant larvae undergo metamorphosis and begin to migrate from the breeding ponds in the late summer and fall during rainy periods (Healy, 1975). A recent study demonstrated that the Eastern Newt (Notophthalmus viridescens) subspecies genetically differ in expression of life-cycle polyphenism.However, we currently lack direct evidence that the life-history divergence among the newt subspecies is associated with the suggested … Within the Adirondacks, they can be found in a variety of wetland ecological communities, including marsh headwater streams and vernal pools. The smooth newt (Lissotriton vulgaris) spends most of its adult life on land, but courtship and mating occur exclusively in aquatic environments during the appropriate season, according to the Online Field Guide. Office of Research and Development. John Eastman. It has an unusual 3-part life cycle: it begins life as a fully aquatic creature with visible gills, and then enters a terrestrial bright orange “eft” stage (often encountered by hikers), and finally returns to the water as a yellow and green adult. Adults are two-toned. The terrestrial Red Eft feeds on earthworms and arthropods found within leaf litter. The egg hatches within three to five weeks into a brownish-green larva, which uses gills to breathe and lives in water. Both juvenile and adult Eastern Newts also fall prey to a variety of predators, despite the toxic skin secretions used to deter them. Some newt species even wrap leaves around each egg individually to camouflage them, according to San Diego Zoo.
