Abstract:

Echolocation is a complex biological traits that collaborated by multiple systems. Its origin can be traced back to 68 million years ago, and repeatedly appeared in multiple vertebrate groups in the subsequent biological evolution. The strong vitality has become a typical case of the convergence evolution in nature. However, it was not until the beginning of the 20th century that humans really opened the prelude to the research on animal echolocation, and became research hotspots in the fields of zoology, behavior, and genetics, and achieved rich results in the past 80 years. In this review, we summarize the development history of animal echo positioning, summarize different echo positioning animal groups in detail, and focuse on the research progress of echo positioning in sound mechanisms, acoustic characteristics, and high-frequency listening mechanisms in order to provide reference for comprehensive understanding of animal echo positioning.

Key words: vertebrate, echolocation, vocal mechanism, acoustic characteristics, high-frequency hearing
