'Singing' frogs when mating

Chinese scientists discovered the frog frog's strange "singing" behavior during mating, to invite and enhance the competition between male frogs.

According to the researchers, the rhythmic cry of the Emei female frogs attracted male frogs. When you hear these sounds, the male frog will move gently to wherever they hear those sounds during mating.

The results of the study have just been published in the Journal of Animal Behavior, revealing a new task of female frogs' mating during mating season. Previously, these sounds were known to function as attracting heterosexual frogs, helping frogs to find a couple for themselves. This is like crickets and other insects that do during mating season.

The singing of female frogs Emei not only invites mates but also makes male frogs compete for mating.

But the research group of the Chengdu Institute of Biology, China, also discovered the cry not only to stimulate mating of males but also to stimulate competition among males. This is good for female frogs.

Not only did the male frogs compete with each other, but the struggle also helped female frogs find partners in their first mating. If females make a sound before mating begins and males also struggle, females soon find males in the dark easily.

Moreover, when the researchers tried to hinder this action by keeping the male frogs, the female frogs continued to make a sound until the males freed.

The researchers wrote: 'During mating, male frogs will move back and forth smoothly instead of making a sound. Meanwhile, the frogs let out a cry at a time between male frog movements. This new action has never been seen in any other frog. '
