Amphibians vary considerably in their hunting practices. The vast majority of anurans and salamanders use vision to hunt prey. Once a prey is sighted, it may be followed for a short distance any then captured. Sight is also important in identifying kinds of prey, such as those with a large energy content and or that may be distasteful or harmful. For example, toads learned to reject bumblebees by sight alone.
Amphibians also use smell and hearing to hunt prey.
Some species of toads can locate prey just by smell alone. Smell sense is of great value in tracking the prey, once it is located. Some amphibians can also detect insects by the sounds they make. A species of toad, Bufo marinus, is attracted to calling insects. Many caecilians and large anurans use fang like teeth to hold struggling prey.
