What do some animals rely on to transmit information?

There is a lot of information about nature, animals and migration. It is one of several bars here. Some animals rely on sound to transmit information, such as herbivores on the African savannah. When predators attack, they meet snoring bees, looking for nectar and sending messages through dancing. Ants transmit information by touching their antennae. Insects release pheromones to transmit information, and dolphins emit sound waves. Wait a minute.
