Sea Otters Using Kelp as Anchor

Sea otter floating among kelp

Looking for inspiration for our book about Keystone Species, I stumbled upon this wonderful contribution to the Biomimicry Institute’s Youth Design Challenge 2021

The students designed a solution to protect people living in flood-prone areas, drawing inspiration from several animals at once. The homes themselves take their teardrop shape from a swordfish’s hydrodynamics, with a waterproof “skin” modelled on the box-patterned gecko. But the cleverest detail is how the houses stay put: otter-inspired chains anchor each home to its neighbours and to the ground, echoing — as the students put it — “just as the kelp otters hold onto kelp to prevent themselves from floating away.” Even the chains linking house to house borrow from otter behaviour, imitating how otters hold hands with each other while they sleep so they don’t drift apart.

Frequently Asked Questions

What is biomimicry?

Biomimicry is the practice of looking to nature for solutions, then applying what we learn to design and problem-solving. Instead of inventing from scratch, it means studying how plants, animals, and ecosystems have already solved a challenge — like staying cool, collecting water, or absorbing carbon — and adapting that strategy for human use.

How does biomimicry help address climate change?

Nature has been adapting to extreme conditions for billions of years, so many organisms already hold working solutions to problems we now face at a larger scale — cooling buildings without electricity (termite mounds), collecting water in drought (the Namib beetle), protecting coastlines from storms (mangrove roots), and capturing carbon (corals, forests, kelp). Biomimicry means studying those solutions and applying the same principles to human design.

How can children get involved in biomimicry?

Children don’t need special training to think like a biomimicrist — just curiosity and a habit of asking “how does nature solve this?” Simple ways to start include a backyard scavenger hunt for nature’s patterns, a “design-an-animal” challenge for a changing climate, or building a small model (like a passive-cooling structure or a water collector) inspired by something they’ve observed outdoors.

Is biomimicry only for scientists and engineers?

No — biomimicry is as much a mindset as a profession. Anyone can practice it by observing nature closely and asking design questions. Professional biomimicry practitioners apply it in architecture, materials science, and engineering, but the same core skill — careful observation followed by “what if we built it that way?” — is exactly what this post’s classroom and family activities are designed to build in children.
