Whale Talk: Listening to Ocean Chatter to Save Them and Redefine Language

Scientists use hydrophones and AI-driven analysis to decode belugas’ infant babble and self-identifying calls, map dialects across humpbacks, orcas and sperm whales, and link vocal patterns to behavior and vulnerability. The work highlights how noise pollution, shipping and warming oceans affect communication and conservation, and it explores using acoustic data to inform targeted protections—while debates continue about whether whales truly have language and the ethics of attempts to converse with them.

Hidden Depths: Blue Whale Calls May Evade Orcas Over Long Distances

A 2025 Marine Mammal Science study shows blue whales vocalize at ultra-low frequencies that travel far through seawater, but killer whales hear best at higher frequencies; beyond roughly a kilometer, orcas may largely miss the calls, giving blue whales a private long-range communication channel that could aid predator avoidance and mating, though increasing ocean noise could mask signals.

First-ever Recording of Echidnas Communicating Unveiled by Curtin University Researchers

Researchers from Curtin University in Australia have recorded the rare sounds of echidnas cooing, grunting, and making other vocalizations during the breeding season, providing evidence that these spiky Australian critters are capable of vocalizing. Previously, it was believed that echidnas only made "sniffing" noises. The discovery of echidna vocalizations helps resolve the scientific debate about when early mammals started using sound to communicate and suggests that acoustic communication likely developed 100 to 200 million years ago. The study also highlights the need for further research to understand the purpose and meaning behind echidna vocalizations.
