because only males emit mating calls.
Because only the males calls.
The testes.
No, there are female frogs and male frogs.
No, male frogs can only mate with females.
its not a theory its a fact
Yes, both frogs and toads have vocal sacs. These vocal sacs are like inflated balloons on the sides of their throats that help amplify and project their calls during mating season. The air that is pushed into the vocal sacs creates the distinct sound that we commonly associate with frogs and toads.
Frogs don't squeeze other frogs to death. Sometimes you may find to frogs and the one on top (a male) holds on pretty tight to te bottom one, the female. The male is kind of guarding her to make sure he is the only male to fertilize her eggs. It is not the intension to squeeze her to death for obvious reasons...
No, male cats do not meow when they are in heat. Only female cats exhibit vocal behavior when they are in heat.
Boy frogs have a black, feltlike substance on the inside of their front legs. Girl frogs do not have the black substance, but have a triangle, almost like a tail in between their back legs. Male frogs have enlarged "thumbs" on their front feet. These are grippers used to grasp the female during mating.Females are larger and makes also have almost like a 6th toe on their back feet. It's for holding onto the females during mating.The females are big but the males croakThe ears, or tympanic membrane (the circle "thingy" right behind the eyes) in males is larger than his eye. In females, the tympanic membrane is smaller than the eye.There is no easy rule to determine whether a frog is male or female. In some species the male is larger; in other species the female is larger. In many species, only the male makes the sound. Males are always the ones with the sac beneath their throat that inflates as they make their sounds.The way to tell the difference between a male frog and a female frog varies between species. For instance, in some frogs (like wood frogs), Males have enlarged, dark, rough pads on their thumbs that they used to grasp female frogs. Females do not have these patches on their thumbs. In other species of frog, the differences may be more subtle. For instance, male pacific chorus frogs have darkened, loose skin around their throats to allow the skin to expand when they call. Females have plain white skin.Often, many of these differences between male and female frogs only appear during the breeding season.
The only way I have found to stop my cat bringing in frogs is to keep the back door shut. Sorry.
No. Some true toads (Bufonidae) can change from a male to a female, but only in special circumstances.
Coquis are small frogs, who are native to, and only found on Puerto Rico.
