ボディーランゲージ
Inter organismic communication in communication between organisms of the same species (conspecifics), this includes human speech. Especially in humans, communication is key to upholding social structure. Dolphins likewise communicate with one another in a number of different ways by creating sounds, making physical contact with one another and through the use of body language. Dolphins vocally communicate through clicking sounds and pitches of whistling specific to only one individual. The whistling helps communicate to other dolphins the location of that individual. For example, if a mother loses sight of her offspring, or when two familiar individuals cannot find each other, their individual pitches help navigate back into a group. Body language can be used to indicate numerous things such as a nearby predator, to indicate to others that food has been found, and to demonstrate their level of attractiveness in order to find a mating partner, and even more. However, mammals such as dolphins and humans are not alone communicating within their own species. Peacocks can fan their feathers in order to communicate a territorial warning. Bees can tell other bees when they’ve found nectar by “dancing” when they return to the hive. Deer may flick their tails to warn others in their trail that anger may be approaching.
