Considering the 'Lifestyle and Ecology of Amphibians' section, which of the following comparisons is accurate?
A: While frog tadpoles are typically aquatic herbivores, salamander and caecilian larvae are generally strictly terrestrial carnivores.
B: Unlike young frogs, which develop legs and lungs during metamorphosis, salamander and caecilian larvae look much like the adults.
C: Fertilization in all amphibians is internal, and they lay shelled eggs on land.
D: Amphibians are unique among vertebrates for undergoing a 'dual life' stage, meaning all species live first in water and then on land.
Explanation
The 'Lifestyle and Ecology of Amphibians' section states: 'Moreover, salamander and caecilian larvae look much like the adults, and typically both the larvae and the adults are carnivorous.' This directly supports option B by contrasting them with frogs, whose larval tadpole form is distinctly different from the adult.
