Summary

Story summary

Project Ceti researchers report that sperm whales possess a complex communication system resembling human speech.
Their vocalizations reach up to 230 decibels and include codas that function like an alphabet for social interaction.
The codas are used for bonding during birth and coordinating hunts, demonstrating structured communication.
Advanced acoustic analysis shows these sounds are structured, enabling researchers to map communication patterns and social dynamics.
