Sexual selection in amphibians involves
sexual selection processes in
amphibians, including
frogs,
salamanders and
newts. Prolonged breeders, the majority of frog species, have breeding seasons at regular intervals where male-male competition occurs with males arriving at the waters edge first in large number and producing a wide range of vocalizations, with variations in depth of calls the speed of calls and other complex behaviours to attract mates. The
fittest males will have the deepest croaks and the best territories, with females known to make their
mate choices at last partly based on the males depth of croaking. This has led to
sexual dimorphism, with females being larger than males in 90% of species, males in 10
nd males fighting for groups of females. .
