Drones Capture Sperm Whales Using Heads in Rare Head-On Encounters

Drone footage off the Azores and Balearic Islands provides the first direct observations of sperm whales colliding head-on, lending empirical support to the idea that the spermaceti organ functions as a battering ram. The three documented head clashes involved sub-adults, leaving the exact purpose—whether in mating contests or other social interactions—unresolved. While the findings confirm a long-standing anatomical hypothesis, they also underscore the need for more extensive drone-based monitoring to determine how common and why this behavior occurs.

Male Sperm Whales Sound Ocean’s Loudest Clangs, Study Finds

New research shows male sperm whales produce the loudest known animal communication signals, emitting slow, low-frequency clangs that can be heard by other whales up to about 70 kilometers away. Hydrophone recordings from the Seychelles and other sites reveal a distinct rhythmic pattern with 5–10 second gaps. The sounds are produced by the whales’ massive nasal structures (phonic lips), but scientists still don’t know the exact purpose—possibilities include attracting mates or deterring rivals—so further study is needed.

Bubble bursts help sperm whales stay neutrally buoyant while napping

A study tagging 42 sperm whales found that, during resting dives, the whales blow bubbles to counter lung gas expansion and maintain neutral buoyancy, especially when resting nearer the surface (about 11 releases) versus deeper returns (3–4 releases). Deeper rests show fewer bubble releases, suggesting a buoyancy-control function, while the whales likely sleep with one brain hemisphere at a time to breathe and stay vigilant. The findings were published in the Journal of Experimental Biology.

Whale Codas Hint at Human-Like Language in Sperm Whales

UC Berkeley researchers studied 15 sperm whales over four years, attaching underwater microphones and analyzing codas; they found two frequency-based, vowel-like click types (a and i) that can form diphthongs, with different pods using distinct frequencies—suggesting regional accents and a highly complex system similar in pattern to human speech, published in Proceedings of the Royal Society B.

Sperm Whales Reveal a Sophisticated Vocal Alphabet

New research analyzing 2014–2018 recordings of Caribbean sperm whales finds signs of a highly complex phonetic system in their calls, including vowel-like patterns and diphthongs. Using GANs within Project CETI, scientists identify vowels differentiated by inter-click intervals and suggest these whales may have a developing vocabulary, with a goal to interpret around 20 expressions (e.g., diving, sleeping) by 2031.

Whale Talk Mirrors Human Language, New Study Finds

Sperm whales’ codas show vowel-like differences and tonal patterns arranged in multi-layered structures that closely resemble human phonology, suggesting parallel evolution of language-like signals. The findings from Project CETI and UC Berkeley researchers, published in Proceedings B, push forward the goal of understanding whale speech and eventually enabling interspecies communication, though significant work and funding remain.

Sperm Whale Codas Reveal Human-Like Phonology

New analysis of 3,948 sperm whale codas from 15 individuals finds two formant-based coda types (a-codas and i-codas) with timing and contextual rules resembling human phonology, indicating a highly structured communication system that stops short of being language. Project CETI frames this as a major step toward decoding whale speech and understanding language evolution.

Drones Capture Sub-Adult Sperm Whales Headbutting for the First Time

Drones recorded three headbutting incidents among sub-adult sperm whales off Spain and Portugal (Azores and Balearic Islands) between 2020–2022, marking the first video evidence of this behavior and challenging the idea that only adult males headbutt. The footage suggests rough play or social dynamics as young whales leave matriarchal groups, and researchers note that headbutting is unlikely to injure them. The study, published in Marine Mammal Science on March 23, 2026, highlights drone observations as a powerful tool in marine research and partly connects to sailors’ lore about whales sinking ships.

Sperm Whale Birth Captured with Unexpected Herd Support

Researchers filming off Dominica captured a rare birth of a sperm whale in which surrounding females—related and unrelated—cooperated to support the laboring mother and calf, a first documented instance of birth assistance in non-primates, with vocal changes suggesting coordinated care.

Sperm Whale Birth Captured: Females Rally to Shield Newborn Calf

Scientists documented one of the most detailed wild observations of a sperm whale birth, revealing cooperative female behavior as they protect the newborn calf and help it reach water safety, with observations tied to Project CETI.

Sperm Whales Orchestrate Cooperative Birth, Keeping Calf Afloat as a Tight-Knit Group

Field observers off Dominica in July 2023 captured an 11-whale group from two matrilines coordinating a calf’s birth and postnatal care, with a core quartet lifting and maintaining the newborn at the surface for breathing while the wider group stayed cohesive; the study, aided by machine learning and computer vision to track individuals, provides rare quantitative evidence of allocare and complex sociality in sperm whales and was published in Science Advances.

First On-Camera Sperm Whale Headbutts Documented, Initiated by Young Whales

Researchers captured the first documented on-camera headbutts between sperm whales, observed in the Azores and Balearic Islands, showing that young whales initiate the behavior; the study, published in Marine Mammal Science, seeks to understand its function and invites others with footage to share.

Drone Footage Reveals Sub-Adult Sperm Whales Engaging in Headbutting

University of St Andrews researchers used drones to document headbutting among sub-adult sperm whales in the Azores and Balearic Islands, overturning the idea that this behavior is limited to large adult males. The study, published in Marine Mammal Science, notes questions about why the behavior occurs and how it affects group dynamics, and highlights drones as a powerful tool for observing near-surface whale actions, echoing historic anecdotes of whales ramming ships.

"Earth's 32 Loudest Animals Revealed"

The article explores 32 of the loudest animals on Earth, ranging from the blue whale, which can emit calls up to 188 decibels, to the tiny African cicada, whose mating call reaches 107 decibels. It highlights the diverse ways these animals use their loud calls for communication, mating, and hunting, and includes fascinating details about each species' unique vocalizations and behaviors.

"Rare Video Captures Epic Battle Between Ocean Titans, Leaves Boaters in Awe"

Tourists in Australia witnessed a rare and intense battle between orcas and sperm whales during a whale watching expedition. The orcas chased and attacked the sperm whales, leading to a dramatic and unexpected encounter. However, further analysis revealed that the sperm whales used a defensive tactic of releasing feces to deter the orcas, ultimately thwarting the attack. The event provided a unique and privileged insight into the behavior of these oceanic giants off the southwestern coast of Australia.
