Do you speak orca?

Orcas and their incredible ingenuity fascinate scientists. Closely related to dolphins, living in groups, these apex predators possess a collective intelligence that is beyond us and their own verbal language: 24 different sounds have been recorded that constitute the basis of their phonetics, enabling them to pronounce around 60,000 words.
Report by Carol Haefliger for "Mise au Point", the RTS magazine programme.

Guests: Carol Haefliger, journalist with RTS; Olivier Adam, bioacoustician, specialist in the sounds made by cetaceans.

Presented by: Dominique Laresche.
