Is She Part of the World’s Cutest Camera Crew?

How a team of sea lions is helping with important ocean research

    Australian sea lions are known for a few things. They’re excellent hunters. They’re playful and smart. And with their round bellies and puppylike faces, they’re incredibly cute

    But recently, they’ve taken on a new role: research camera crew.

    So how did these ocean creatures land this important job

    The ocean covers about 70 percent of our planet. Scientists and explorers have been studying it for centuries. And yet, much of it remains a mystery.

    On average, the ocean floor (or seabed) lies about 12,000 feet below the water’s surface. That makes it challenging to explore. The deeper you get, the more dangerous it is for humans

    But even at more shallow depths, exploring isn’t easy. Scientists often use tools called remotely operated vehicles (ROVs). These machines can explore seabeds and record videos or photos. However, using them can be costly. Rough winds and stormy waters can also make them hard to operate.

    Overall, only a quarter of the ocean floor has been mapped by scientists. It really makes you wonder: Could there be another way to learn about the ocean’s unknown?

On a Mission

Tiny cameras  were glued on the backs of eight sea lions. (Don’t worry—it didn’t hurt them!) 

    Enter Nathan Angelakis. He’s a scientist in Australia. In 2022, his team wanted to learn more about the seabeds off of Australia’s southern coast. And he’d come up with an interesting idea. Why not get local sea lions to help

    After all, the animals were excellent divers. And they were already familiar with the seabeds. That’s where they usually hunted for food

    Angelakis’s team chose eight healthy sea lions. They attached tiny cameras and GPS trackers on the sea lions’ backs. Within a couple of days, the animals had covered nearly 348 miles. They captured dozens of hours of video footage. Much of that footage showed areas that had never before been recorded by scientists

    The video footage may prove to be very important. Over the past 40 years, the Australian sea lion population has gone down. Currently, the animals are considered endangered, or at risk of dying out

    But now scientists know more about their habitat, or home. And they can use what they have learned to protect these creatures.

    In that way, the sea lions aren’t just helping the scientists. They’re helping themselves too
