Why do frogs croak?
Show answer & explanation
Answer: Attracts mates and defends
Attracts mates and defends ✓ — Correct! Vocal mating and territory! Male frogs croak primarily for: (1) Attracting females—species-specific calls (each species unique frequency/pattern). (2) Territory defense—warning other males. (3) Chorus effect—synchronized calling amplifies signal. Mechanism: vocal sacs inflate (amplify sound), can be very loud (some 100+ decibels)! Females choose mates by call quality. Bigger frogs = deeper calls. Only males croak in most species. Peak during breeding season (spring). Croaking uses enormous energy!
Croaking clears their throat — Wrong. Frogs don't clear throats. Croaking is deliberate vocal signal—attracting mates and warning rival males during breeding.
Helps with breathing underwater — Wrong. Croaking doesn't aid breathing. Frogs breathe through skin underwater. Croaking is vocal mating call and territory defense.
