Communication is an adaptation of animals to help them interact with members of its own species, other animals in general, and the world!
Mice communicate in two ways, the first is in the human range,(with squeaks) for long-distance warnings, and in the ultrasound range, for short-distance communication. Mice also rely on pheromones for social communication. They can also sense surfaces and air movements with their whiskers.
Fireflies communicate by using their bio-luminescent lower abdomen to signal each other and attract mates. Also, male members of some species, such as cicadas and fireflies, get together and put on a large display to attract more females.
Another animal that has good communication skills is the owl. It uses sounds and body movements such as hooting, calling, hissing, posture, fluffing feathers, and bill snapping to communicate. They also have excellent eyesight and can hear very well. Their ears are not located directly opposite of each other, so this helps them to pinpoint small sounds.
