Happywhale Happywhale tracks individual whales throughout our world's oceans. What is Happywhale.com about? The vast majority of these are only known by five digit ID .

We have two goals: One, to open to you the wonderful world of knowing whales as individuals, and two, to create a deeper understanding of whales both through education and improved science. This work is a collaboration with Cascadia Research Collective of Olympia, Washington, to whom we provide whale encounter date gathered through participatory citizen science. Currently we are focused on the Humpback Whale population of coastal California, with plans to expand as we are able both to other regions and other species such as Blue Whales. We are still in a beta phase — please bear with any rough edges (and give us feedback!) You can upload images of Humpback Whale tails (flukes) via the ’Submit Images’ button at Happywhale.com. For every submitter, we will create an account and we will attempt to match your whales. As we develop, we will give you a login with access to your encounters, the history and stories that we know for your whales that we successfully match, and an ability to connect with others who have encountered the same whales. Meanwhile we will be sharing this data with scientists who use the data gathered to improve our understanding of whale population health. WHALE NICKNAMES — ASKING FOR YOUR INPUT!: Our known population comes from decades of work by Cascadia Research Collective, with upwards of 3000 individuals in the catalog. But we know some of these whales have nicknames that are already in use by specific groups. We want to gather these nicknames. If you have images of any Humpbacks or other California whales you know by name, please share (via the link on Happywhale.com — put nicknames in filenames, in the text field in the file submission process, or send by email to [email protected]). We’ll gather known nicknames for use in the system. We would love for you to participate, to try to ID your photos, and to hear what you think of these efforts. Thank you for your interest!

If you’ve ever wondered how we can recognize an individual whale years later, or even across oceans, you’ve come to the right place.

The truth is, it’s a lot like detective work!

Every whale has a unique combination of features. We don’t just look at the fluke, we examine dorsal fins, pigmentation patterns, scars, cookie-cutter shark bites, entanglement marks, propeller scars, and other natural markings that make each whale one of a kind.

Some clues are obvious. Others take years of experience to recognize.

At Happywhale, our AI helps narrow the search by comparing your photo against hundreds of thousands of whale encounters. From there, our experienced data managers carefully review the most likely matches, comparing every detail before confirming an identification.

It’s a blend of technology, experience, and a keen eye for detail. It’s how a single photograph can become part of a whale’s story for years to come.

Thank you for helping us build one of the world’s largest photo-identification databases. Every encounter you submit helps us better understand whales and supports research and conservation around the globe.

Stay tuned for the next Behind the Scenes post! If there’s something you’re curious about, let us know in the comments, we just might cover it next!

Meet the people behind the matches!

When you submit a whale photo to Happywhale, it doesn’t disappear into a computer, it lands in the hands of a small team of people who care deeply about whales, conservation, and the quality of the data that supports research around the world.

Every potential match is carefully reviewed by one of our data managers. Every sighting is checked for accuracy. Every encounter is another opportunity to learn something new about an individual whale and the oceans they call home.

This work is part science, part detective work, and part passion, and we’re incredibly lucky to have a team that brings all three together every single day!

Swipe through to meet the people behind the matches, learn a little about what inspires them, and see who reviews your submissions.

Thank you for trusting us with your whale encounters and for being part of this global community. Every photo you share helps tell a whale’s story.

If you’ve enjoyed getting a behind-the-scenes look at Happywhale, let us know in the comments! We’d love to hear what you’d like us to cover next.

Be the Captain, Not the Crew.

Artificial intelligence is changing the way we study marine mammals—but how do we make sure we’re using it effectively?

A new paper co-authored by Happywhale co-founder Ted Cheeseman explores how AI can be thoughtfully developed and used in marine mammal science, while keeping human expertise at the center of the process.

At Happywhale, we see this relationship every day. AI helps us search through enormous datasets and surface the most probable matches, but it doesn’t work alone. Our experienced data managers review potential matches, verify identifications, and make the final call.

AI speeds up the search. People make the decisions.

When used thoughtfully, these tools can help researchers work at a scale that simply wasn’t possible before, while scientists remain firmly at the helm.

That’s what it means to be the captain, not the crew.

Happywhale on Digitel Talk!

How can AI, citizen science, and people around the world come together to help us better understand AND protect whales?

Happywhale co-founder and director Ted Cheeseman recently joined Ian Ginn on the podcast to talk about exactly that.

The conversation dives into how Happywhale combines AI-powered photo identification, human expertise, and millions of photographs contributed by researchers, whale watch operators, photographers, and citizen scientists to follow individual whales and better understand their lives and movements.

Ted also talks about the remarkable recovery of humpback whales following commercial whaling, the challenges whales and our oceans continue to face, and how advances in computer vision and technology are helping researchers work at a scale that simply wasn’t possible before.

And, of course, there’s an important theme running through it all: technology is a tool, but people are what make it powerful. From the people taking photos on the water to our data managers reviewing identifications and the researchers using those data to ask bigger questions, Happywhale is built on collaboration.

A huge thank you to Ian Ginn and the Digitel Talk team for inviting Ted on and giving us the opportunity to share more about the science, technology, and community behind Happywhale!

The episode is about 40 minutes and is available on Spotify, Apple Podcasts, Amazon Music, YouTube, and Digitel Talk.

When people think of Happywhale, they might think of AI, but what many don’t realize is that every single whale encounter submitted to Happywhale is reviewed by a real person, with the help of AI!

Welcome to our new **Behind the Scenes at Happywhale** series, where we’re pulling back the curtain on what it really takes to identify whales, build one of the world’s largest whale photo-ID databases, and support conservation science around the globe.

In this first post, we’re following the journey of a whale photo, from the moment you click “submit” to the moment it becomes part of a whale’s life story.

Our AI helps narrow the search, but it’s our experienced data managers who carefully review every submission, compare identifying features, verify matches, and decide whether we’ve found a familiar whale or met someone new.

One thing we’re especially proud of is that our AI is designed to work with people, not replace them. Every match is carefully reviewed by our experienced data managers, and the AI that powers our search runs on Verda’s renewable energy-powered infrastructure. It’s another way we’re working to advance whale conservation responsibly, for both whales and the planet. We also just recently won the AI for Planet award, more about that soon!

Every submission matters.
Every photo tells a story.
Every contributor helps advance whale conservation.

Stay tuned for our next Behind the Scenes post! And if there’s something you’d like to learn more about, let us know in the comments, we just might make a post about it.

If you have whale photos waiting on your camera roll, we’d love to help you discover who you’ve met!
