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.
Croaching....I think that's how you spell it.
they don't sing like male frogs do if that's what you're asking
Vocal Sac
You are possibily reffering to the inflation and deflation of a frogs "VOCAL SAC."
Animals such as frogs, certain insects, and some plants have storage sacs for solid or liquid content. These storage sacs can be used for storing food, water, toxins, or reproductive fluids.
Poison Dart frogs like to mate in the Spring!
No- when a mother frog has laid her eggs as frogspawn, she moves on. The tadpoles which develop from the eggs make their own way in the world, from hatching through into adulthood. It depends The male Rhinoderma darwiniii of chile takes the eggs into his vocal sacs, where they hatch and eventually undergo metamorphosis. The young frogs climb out of the vocal sacs and emerge from the males mouth. Female Eleutherodactylus sit on their eggs until they hatch, not to provide warmth but to prevent the eggs from drying out. The female normally lays eggs in trees or bushes, where they may dry up. (this type of frog is extinct)
Frogs do not have air sacs like birds do. Instead, they possess lungs for respiration, which are less efficient than avian air sacs but sufficient for their needs. Frogs can also absorb oxygen through their skin, allowing them to breathe while submerged in water. This dual respiratory system is essential for their survival in various environments.
allows male to produce a mating call.
They have different nasal sacs and muscles next to nasal passages.
