Why did the deep-sea anglerfish captivate an entire generation on TikTok?

There are viral phenomena one can predict – and then there’s the anglerfish. Last week, something unfolded on social media that few could have expected in their 2025 bingo card. A small, peculiar fish, designed to live in darkness, suddenly swam to the surface in what appeared to be one last desperate journey.

A moment later, it was dead. A scientific curiosity? Perhaps. But on TikTok, it became something else entirely – a metaphor for life, freedom, and the courage to break free. A small fish, which had once swum anonymously in the shadows of the deep, became a viral sensation and an existential reflection for millions of users.

TikTok was flooded with videos of this strange little fish, and in the comment sections, emotional reflections followed – on life, courage, and taking the leap into the unknown. How did a dying fish become a symbol of our time? And what is it about this tiny being that moves us so deeply?

Perhaps it’s about contrast. We live in a world where perfection is rewarded, where our lives are meticulously curated down to the smallest detail. And then this little fish appears – ugly, alone, and lost – reminding us of something we may have forgotten: authenticity and unpredictability are what truly resonate in an era where everything is filtered and staged.

This tiny fish is a reminder that predicting what will go viral and strike an emotional chord on social media is becoming increasingly difficult. For those of us working in communications, this means that we must once again recognize that people are no longer drawn to polished, pre-packaged messages – they seek something that feels deeply real (no pun intended).

Our audiences now shape the narrative, and it’s no longer about selling an idea but about creating something that moves, provokes thought, and speaks to profoundly human emotions of courage, sacrifice, sorrow, and identity.

Take Duolingo’s owl, for example, or why not the internet’s favorite viral hippopotamus, Moo Deng? The common denominator – aside from being animals – is that they demonstrate what truly engages social media users. Duolingo has turned its green owl into a humorous TikTok icon with its own storylines. Moo Deng, the viral hippo that took over both social and traditional media, became a symbol of how a creature without any inherent message can spark massive engagement, drawing thousands of visitors to Khao Kheow Open Zoo in Thailand. The hippo even has its own Wikipedia page now, as it should.

We turn to social media for a break from the serious world, even as we know these platforms increasingly take a toll on our mental well-being.

The deep-sea anglerfish raises questions about identity, change, and our desire to break free. It stands as proof of the power of storytelling – especially when we, as the audience, are allowed to participate in the narrative, to laugh, cry, and reflect, without any specific agenda.

The anglerfish has now become a metaphor for something far greater than itself. It is the employee who dares to leave a stable job despite uncertainty. It is the creative professional who steps away from security to follow their passion. It is all of us, living in a time where we must choose between staying in the familiar or risking everything for the chance to experience something new.

Perhaps that’s why we can’t let go of this strange, 18-centimeter-long fish with an ocean’s worth of courage. Call it storytelling, co-creation, or some other trendy industry term, but the fact remains: this tiny fish brought millions of people together, inspiring them to create content, comment, share, and spread its story – a viral phenomenon with a message about daring to believe in something bigger, even if only for a fleeting moment.

And in the end, that’s what makes this phenomenon so powerful. The deep-sea anglerfish became a symbolic creature – one that survives by generating its own light, but that one day chose to seek something greater beyond itself.
