The term "animal languages" is often used for non-human systems of communication. Linguists and semioticians do not consider these to be true "language", but describe them as animal communication on the basis on non-symbolic sign systems,[26] because the interaction between animals in such communication is fundamentally different in its underlying principles from human language. According to this approach, since animals aren't born with the ability to reason the term "culture", when applied to animal communities, is understood to refer to something qualitatively different than in human communities. Language, communication and culture are more complex amongst humans. A dog may successfully communicate an aggressive emotional state with a growl, which may or may not cause another dog to keep away or back off. Similarly, when a human screams in fear, it may or may not alert other humans of impending danger. Both of these examples communicate, but both are not what would generally be called language.

In several publicized instances, non-human animals have been taught to understand certain features of human language. Karl von Frisch received the Nobel Prize in 1973 for his proof of the sign communication and its variants of the bees.[27] Chimpanzees, gorillas, and orangutans have been taught hand signs based on American Sign Language. The African Grey Parrot, Alex, which possessed the ability to mimic human speech with a high degree of accuracy, is suspected of having had sufficient intelligence to comprehend some of the speech it mimicked. Though animals can be taught to understand parts of human language, they are unable to develop a language.

While proponents of animal communication systems have debated levels of semantics, these systems have not been found to have anything approaching human language syntax.[28]
