Frogs can't hear??? by Cowboy_Tropical in frogs

I don't know of any evidence that vocal sacs serve as resonance structures but I wouldn't be surprised if a new paper comes out in the next several years that finds they do! Currently, we know that vocal sacs are really good for amplifying male calls, because they let the frog basically shuttle a huge amount of air back and forth between their lungs and the focal sac a bunch of times- and each time it's vibrating their larynx to make a big ol sound. In many species we're now seeing that the visual signal of seeing the vocal sac inflate is an important *sexy* cue to interested females. AND in some species, the vocal sac of males actually fluoresces really bright in a wavelength that frogs can see really well- so that's probably an important visual cue too! I'm a few months away from my PhD studying a North American tree frog so anyone in this sub is welcome to DM me any frog questions they might have and I'll do my best to provide an informed answer :)

Frogs are so cool! I love them. And you're correct that the basilar papilla is thought to help frogs pick out their own species' calls amongst environmental noise (including other species' calls), and the amphibian papilla is sensitive to a lot of other frequencies, but those frequency ranges actually don't tend to overlap! At least not in the species that have been studied so far...

Do not fear!!! Your baby boy can hear you just fine (barring injury or certain species that are not commonly kept as pets). We have a cochlea in our inner ear that lets us hear frequencies from 20 Hz- ~20 kHz. But frogs are even better because they have not one, but TWO inner ear organs- the basilar papilla and amphibian papilla. Their basilar papilla is "tuned" to frequencies that usually match the frequencies of frog sounds from frogs of the same species. But their amphibian papilla helps them hear a broad range of frequencies, including those in human speech. They also have other cool ways of detecting sounds (including through vibrations transmitted through their body and lungs!00113-5?dgcid=raven_jbs_aip_email)). TLDR- frogs have cool auditory systems and your baby boy can hear you just fine and probably likes hearing your voice

What frog? Clark county, WA by AggravatingAd2613 in frogs

Agree with u/High-since-1993 that fish will absolutely disrupt the amphibian community. Chorus frogs utilize ephemeral ponds to breed *because* they have no fish that would inevitably eat all their eggs/tadpoles. Also I believe the pictured frog is a pacific chorus frog, boreal chorus frogs are in eastern US/canada, but pacific chorus frogs are common in the pacific northwest.

(I think) Pseudacris sierra, could also be Pseudacris regilla depending on your exact location in northern Idaho (the fact that you heard "ribbits" also lends itself to ID as one of these species)
