Latest Odorrana Stories
UCLA scientists report for the first time on the only known frog species that can communicate using purely ultrasonic calls, whose frequencies are too high to be heard by humans.
Most female frogs donâ€™t call; most lack or have only rudimentary vocal cords. A typical female selects a mate from a chorus of males and then â€“ silently â€“ signals her beau. But the female concave-eared torrent frog, Odorrana tormota, has a more direct method of declaring her interest: She emits a high-pitched chirp that to the human ear sounds like that of a bird.
Bats, whales and dolphins use it to communicate. Baby rodents call their mothers with it and now a rare Chinese frog has shown it can hear and respond to ultrasounds, scientists said on Wednesday.
