A perfect example of evolution. In image eggs of Amboli Bush Frog (Pseudophilautus amboli) has evolved them self from stages of tadpoles. Being tadpole predated by various means like bigger frogs or snakes or other insects, frogs of this species doesn't go through tadpole stage and develope themself in a protection of eggs only by skipping tadpole stage and getting predated. By this mean survival is not assured as eggs too might get predated but ratio is lesser as compared to tadoples.
