The Conservation Dilemma: Why Deepwater Sharks Need Our Attention

When it comes to conservation, the species that receive the most attention are not always those in greatest need, but rather those that capture our empathy. Our perception – whether we find a species beautiful, majestic, useful, or threatening – often dictates the efforts we put into their protection.

Sharks are a prime example of this bias. Historically feared and misunderstood, sharks have been ignored or even persecuted in conservation efforts. For years, they were seen as dangerous predators, and therefore they were left unprotected. However, perceptions are slowly changing. Chondrichthyans (sharks, rays, and chimaeras) are gaining recognition in scientific research, and more protective measures are being implemented. However, this shift remains influenced by human perceptions. Species that are seen as less relatable, charismatic or cute are still overlooked.

Deepwater sharks are perhaps the most ignored of all. Often labelled “ugly” or uninteresting, these species live in an environment which is alien to us, making it harder for people to empathise with them. Yet, these sharks are among the most vulnerable. Adapted to extreme depths, they reproduce slowly, meaning that even small disruptions can affect importantly their populations.

So why should we care about these overlooked species? Just because a species isn’t “beautiful” doesn’t mean it doesn’t deserve protection. And it’s not just about altruism. From a more self-interested perspective, we need deepwater sharks. These sharks play a critical role in maintaining the balance of marine ecosystems, which directly supports the sustainability of marine resources that we rely on. Their loss could trigger cascading consequences throughout the ecosystem.

We need to minimize their capture and improve their post-capture survival. The data we gather on their behaviour and physiology can inform better conservation practices. Our goal is to understand the impacts of fishing on these species and develop effective management plans. We must prioritize protecting species that are truly at risk, and deepwater sharks are among those in greatest need.

And you know what? I get it—deep-sea sharks aren’t everyone’s idea of “beautiful.” They’re not flashy like a dolphin or cuddly like a panda. But to me, they’re perfect in their own quirky way. Their weird shapes, their eerie eyes, their adaptations to life in total darkness—it’s like nature’s most fascinating art project. So, call me biased, but I think they’re absolutely stunning. Beauty isn’t just about looks; it’s about the story they tell. And these sharks? Their story is one worth protecting.
