CETI is applying advanced machine learning, state-of-the-art robotics, and underwater acoustics to listen to and translate the communication of whales in Dominica and beyond.
We’re glad you are swimming along with us as we continue to listen to and learn from the whales.🐳💙

New research reveals sperm whale vocalizations are one of the most phonologically complex communication systems in the animal kingdom, representing the closest parallel to human phonology of any known animal communication system.
CETI scientists led by CETI Linguistics Lead Gašper Beguš have revealed that not only do sperm whale vocalizations sound like human vowels, they also behave like them, revealing pattern-like structures across several linguistic dimensions.

What might happen if we could truly understand what whales are saying?
Together with the National Geographic Society, #NatGeoExplorer @DavidFGruber and @ProjectCETI (Cetacean Translation Initiative) have embarked on an epic odyssey to translate the language of sperm whales. By bridging advanced machine learning with gentle robotics, they are creating the first-ever blueprint of a non-human species’ communication.
Today, we launch Listen to the Whales — a global invitation to explore the rich communal lives of sperm whales and discover why deciphering their world matters. Take the plunge and immerse yourself in the journey at the link in bio.

Behold the juvenile wunderpus🐙
Young wunderpuses start life as translucent drifters. As they grow, they settle on the seafloor and develop a distinctive pattern of white stripes and spots on a reddish-brown body, a look which helped earn them their name. No two individuals share the same pattern.
The name Wunderpus photogenicus translates to “photogenic wonder.” They live on sandy or muddy seabeds in shallow waters around Indonesia and Malaysia, and were only formally described as a distinct species in 2006. As masters of disguise and mimicry, they were previously mistaken for other octopus species.
Octopuses are among the most intelligent creatures in the ocean. Some even solve puzzles and use tools. After all, they technically have nine brains.🧠🐙
This post is part of a collaborative series by Project CETI and Kogia covering conservation, the wonder of marine life, and everything in between—follow along for more.

This just in! The latest research shows whales are, in fact, BIG.

Rare sighting: The deepest-diving whales in the world.🐳
On a routine sperm whale research/listening mission, the CETI Team was privileged to get a rare glimpse of this pod of a pod of beaked whales surfacing from the deep off the coast of Dominica. Beaked whales are among the most elusive and least-known mammals on Earth, largely because of their deep diving habits.
There are at least 4 species of beaked whales in the Caribbean, of them the goose-beaked whales are the deepest and longest diving mammals in the world. Holding the record for deepest dive by a marine mammal ever recorded at 2,992 meters or 9,816 feet deep and also for the longest dive at 3 hours and 42 minutes underwater without surfacing to take a breath.
Their distant cousins, sperm whales, are the third-deepest diving mammals, with second place going to the southern elephant seal.

Get to know Hope! One of the many sperm whales we have the privilege of working with in Dominica!🐳🇩🇲
Hope is a member of Unit U, also known as “The Utensils.”🍴Around 2012, after the loss of several adult females in Unit F, or “The Group of Seven,” they merged with Unit U to form a stable unit made up of the two female lines, and have since only been seen together. Sperm whale families need numbers, to ensure the protection of their calves and each other, so when these families got down to very few members, they merged.
Hope is best known for her appearance in “Secrets of the Whales,” a @natgeo and @disneyplus documentary series.
You can learn more and meet more whales at projectceti.org/listen via the link in our bio.

Sperm whale, humpback whale, blue whale or perhaps orca, what would you ask your favorite whale if you could? Dive into the depths of your imagination—into a future where we might understand whales. What would you want to learn from them? Share your message for The Deep Archive at projectceti.org/listen at the link in our bio.🐳🎙️

A huge congratulations to Chelsea Lugay (@sea_chelz_), CETI Fellow alumna, on being selected for the 2026 BIMS Tidal Wave Cohort!🇩🇲
The @bimscience Tidal Wave Program was created to empower emerging voices in marine science through conference sponsorships and professional development opportunities.
The program’s success was recently evaluated and featured in the publication, “Reclaiming Narratives and Redefining Equity: A Values-Engaged, Educative Evaluation of the Black in Marine Science Tidal Wave Program,” contributing to broader conversations about equity and representation in marine science.
Chelsea joins the next wave of leaders, innovators, and change makers in marine science, bringing passion, purpose, and powerful perspectives to the field. Learn more about the Tidal Wave Program on the @bimscience website at the link in our bio!

Audacious grantee @projectceti, led by @davidfgruber, is the largest interspecies communication initiative in history, bringing together more than 50 scientists across eight disciplines with one goal: decode the language of sperm whales.
Using advanced machine learning, state-of-the-art robotics, and underwater acoustics, they’ve done just that, with their discoveries laying the foundation for the first-ever Sperm Whale Language Model.
Hear how their work is reshaping how we understand animal communication and the world around us at the link in bio.

Whales may have lost the joy of tasting a sweet treat over 36 million years ago, but that doesn’t mean they don’t indulge in sea snacks.🍬🦑
The land-dwelling ancestors of the modern whale once chewed and ate plants while their taste receptors protected them from ingesting toxic substances. The whales we know today, including sperm whales, tend to swallow their meals whole, and without the need to chew to release flavors, a broad sense of taste likely became evolutionarily unnecessary. Therefore, somewhere on their evolutionary journey from land to sea, sperm whales’ ancestors gave up their sweet tooth and, as you can see in the photo, became deep-sea squid-loving specialists.🐳
Fun fact: the only marine mammals known to have retained the gene for tasting natural sugars are manatees and dugongs, whose diet is mostly sucrose-rich seagrasses.🌱

Last week we took a deep dive into Dominica’s Blue Economy at Ti Kai Bod Lanmè, as part of the Ti Vilaj Kwéyòl @tivilajkweyol!🇩🇲
Alongside other organizations and actors in the Blue Economy in Dominica, CETI Marine Operations Team Member and Drone Pilot Zahrek Gonzalez-Peltier (@zahrek) shared with visitors the wonders of whales and all about our research, listening to and translating the communication of the sperm whales in Dominica and beyond🐳.
