Story summary

The Project CETI study on sperm whale codas suggests Morse-code–like patterns may convey meaning, analyzed with AI.
Critics argue these patterns could be artifacts or linked to whales’ alertness rather than intentional signals.
Luke Rendell, a marine biologist, says there is no evidence of whale response to these patterns.
Denise Herzing, a CETI team member, acknowledges the study’s innovative approach and its potential for further exploration.
