The difference between a newt and a salamander is that the newt often has an extra stage in its life cycle. Unlike the salamander, it spends two or three years of its life on land as a red eft. Then it returns to the water, where it spends the rest of its life. Most mature salamanders are terrestrial, though they need a moist environment.Continue Reading
Both newts and salamanders begin life as gilled, aquatic larvae. In the case of the newt, it leaves the water after two to five months as an orange-red amphibian with black spots down its side. Unlike most salamanders, the eft's skin is dry and rough.
As the red eft matures, its color changes to brown or green, though the red spots down its side remain. Though the mature newt prefers to live permanently in water, it can live on land if the pond or stream dries up. However, it will travel to find another body of water.
There are some newts that don't become red efts and simply mature into adults. Others retain their larval gills, though they are mature animals and can reproduce. Other newts remain at the red eft stage though they can also reproduce.Learn more about Amphibians
Some, but not all, species of salamander hibernate during the winter months. Salamanders are classified as amphibians, and amphibians cannot regulate their own body temperatures.Full Answer >
The spotted salamander's diet consists of insects, worms, slugs, spiders and millipedes. Despite bright yellow or orange spots along its black body and a life span of up to 20 years, the species is rarely seen by humans, emerging only at night to feed.Full Answer >
The main staples in the salamander's diet are insects, spiders and worms, but salamanders are opportunistic feeders and eat most animals that are appropriately sized. Larger salamanders are able to eat some fish, crabs, small mammals, and amphibians and water insects. Smaller salamanders often feed on beetles and their larvae, flies, earthworms, moths, spiders, grasshoppers, mites and springtails. In dire situations, salamanders may also eat other salamanders.Full Answer >
Moths reproduce when males follow pheromone trails to a receptive female and mate, after which the female lays eggs that hatch into caterpillars, the first stage in the ambulatory portion of the moth's life cycle. Most caterpillars are eaten or die before reaching adulthood, but those that do survive metamorphose into adult moths and fly off in search of mates themselves.Full Answer >
