Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some students are investigating the life cycle of the spotted salamander. They learn that these salamanders must live close to water and lay their eggs in water. After 20-60 days the eggs hatch as larvae that must stay in the water until they mature into adult salamanders. The students infer that the life cycle of the spotted salamander is similar to the life cycle of the frog because both animals-
A
have long tails and strong jumping legs as adults.
B
live near water and produce larvae with wings.
C
lay eggs in water, which hatch into larvae that live in water.
D
produce offspring that hatch from eggs and look like adults.
Explanation: 

Detailed explanation-1: -Spotted salamanders progress through several life stages: egg, larva, juvenile, and adult.

Detailed explanation-2: -Interesting Facts: The skin of the spotted salamander secretes a noxious substance that deters many would-be predators. Predation is most common during egg and larval cycles before the salamander develops its toxicity. Spotted salamanders will even head-butt or bite in self defense.

Detailed explanation-3: -Breeding occurs October through March. Female salamanders lay approximately 90 eggs, which are attached to stones or debris in underground freshwater crevices. The Long-tailed Salamander is mainly a terrestrial species and is generally found under rotting logs and rocks near streams.

Detailed explanation-4: -On average, Salamanders live for about 20 years. Some species might even live up to 50 years. Life span of the same species sometimes may even differ in the wild and in captivity.
