(ORDO NEWS) — Fish can “speak” – there are at least 175 families of ray-finned fish that can communicate using sound signals.
This is stated in the report on the results of a new study by Cornell University, the material is published on the Phys.org website.
Experts studied the family tree of fish and found that sound was so important that it evolved at least 33 times over millions of years.
Three sources of information were used in the study: existing records and scientific articles describing fish sounds, known fish anatomy, and references in 19th century literature before the invention of underwater microphones.
According to scientists, fish “communicate” mainly about food and sex: with the help of sounds, animals try to attract a partner, protect a food source or territory.
