 We know animals don't use speech like humans, but they do use signals or signs to communicate Information to each other. Today we're gonna talk about the use of dishonest signals by some animals. When animals use dishonest signals, they intentionally give false Information about themselves to other animals. This is important for their survival.

So why do animals use diss on a signals? For one, some animals used is on a signals to catch prey. Predators have to get close to their prey to catch them. Obviously, if the prey realizes a predator is approaching, it will try to escape.

 Some credit as used is on a signals and behave like other harm Liszt species in order to get close to their prey. For example, a kind of fish the blending fish performs a dance like that of a fish that normally cleans the skin of other fish without harming them. So when the plenty fish dances in this way, it's pray come close to get their skin cleaned and instead the bloody fish attacks them.

Some animals also used in Sana signals to defend territory. Animals of the same species often try to take over each other's territory or habitat. When an animal is not strong enough to defend its territory, it can use a dishonest signal to appear stronger than it really is. Thus drive away other members of its species that may try to invade its territory. For example, a certain species of shrimp is particularly weak and defenseless when shedding its skin. But when another shrimp tries to swim into its territory, it behave as if it were capable of defend its space BAE wave, it's Claus and acting a grace if the invader is deceived and leaves the area.
