Updated: Jan 30

Discover how the octopus's remarkable camouflage abilities are inspiring a new wave of sustainable and versatile technologies, as explored in the book '30 Animals That Made Us Smarter'.

The Octopus - Nature's Master of Disguise

In the vast and mysterious depths of the ocean, the octopus reigns supreme. A shining example of biological brilliance. This eight-armed ocean specialist – known for its extraordinary intelligence – is also well renowned for its unparalleled ability to camouflage. Disappearing before our very eyes.

But octopuses camouflage doesn't simply allow the animals to blend into their surroundings; it also allows for these animals to become part of them. The skin of octopuses mimics the colours of seaweed, coral, the rocky seabed and it also copies the textures of these objects. This combination of changing skin colour and skin texture helps to make the animal's body virtually invisible to both predator, and prey.

This incredible natural phenomenon has not only captivated the imagination of marine biologists it's also inspired a wave of technological innovations. In this blog post, we explore how octopuses unique camouflage abilities are influencing cutting-edge technologies in the fields of defence, medicine, and wearable tech.

The Octopus's Camouflage Ability

There are many animals which have the ability to camouflage themselves but the octopus takes this mastery to a whole new level. With its chameleon-like ability to change colour & texture the octopus is an animal of constant transformation. This ability is rooted in its unique skin, which contains specialised cells. These cells are made up of three types called chromatophores, iridophores, and leucophores. Chromatophores expand and contract to change the animal's skin colour, while iridophores and leucophores reflect light. The combining effect of these colour changing cells all adds to create a stunning camouflage effect.

What Cells Change Colour in Octopus?

Chromatophores - expand and contract to change the animal's skin colour
Iridophores - reflect light
Leucophores - reflect light

This incredible natural skill allows the octopus not only to hide from predators but also to communicate and even express emotions with other octopus. Make no mistake, this animal's body is a sophisticated biological system. One which that has become a great source of inspiration for scientists and engineers around the world.

Technological Inspirations from the Octopus

The camouflaging ability of octopus - and that of many other animals - has sparked a wave of biomimetic technologies. Engineers and scientists are now drawing inspiration from these ocean dwelling members of the mollusc family to develop materials that can also change colour and texture. One such innovation is in the field of soft robotics, where researchers are creating flexible, adaptive materials that work to mimic the octopus's skin. The hope is that in the nearby future it may offer us potential applications for stealth technology and the wearable devices industry.

Moreover, advancements in materials science have led to the development of fabrics that can alter their appearance, a concept directly inspired by the octopus's camouflage ability. These technologies hold immense potential; from use in defence programs, fashionable camouflage clothing, and even in healthcare. In fact it's led to several ground-breaking technologies.

Here are some remarkable projects that have taken cues from this master of disguise:

Octopus Inspired Projects

UC Irvine's Octopus-Inspired Technology: Researchers at UC Irvine have developed a technology that changes its visible appearance over 500 times with minimal degradation. This system can also autonomously self-repair, and works effectively across the ultraviolet, visible, and near-infrared light spectrum. It holds potential for stealth technology and signalling applications.
Self-Healing Camouflage & Signalling Tech: Inspired by the blue-ringed octopus, this technology can rapidly change colour and appearance under different light conditions. Developed by the University of California Irvine, it can be used in defence, medicine, and robotics.
Programmable ‘Camouflaging' Material from the University of Chicago: This material mimics the octopus's skin papillae, which can extend and retract instantly for camouflage and then smooth out for swimming. Such technology could be used in a range of applications, including adaptive camouflage and light manipulation.
Colour-Changing Camouflage Fabric by Xuesong Jiang: At Shanghai Jiao Tong University, researchers have created a material that changes colour to blend with its surroundings. This material could lead to inexpensive adaptive camouflage uniforms, especially useful for defence applications.

These examples demonstrate the incredible potential of octopus-inspired technologies, offering innovative solutions that could revolutionise various industries.

Implications and Future Possibilities of Octopus-Inspired Technology

The innovations inspired by the octopus's camouflage abilities open a world of possibilities. As we move into the future, these technologies could have far-reaching implications across various industries:

Sectors to Benefit from Octopuses Camouflage

Defence Applications: Adaptive camouflage materials, based on the animal's skin, could be used for stealth operations, making vehicles or personnel virtually undetectable in combat environments.
Medical Advancements: Colour-changing materials could revolutionise diagnostic tools, allowing for non-invasive monitoring of patient conditions through skin patches that change colour in response to physiological changes.
Robotics and Artificial Intelligence: Robots equipped with octopus-like skin could adapt to different environments, enhancing their utility in search-and-rescue operations, exploration, and surveillance.
Sustainable Energy: Materials that mimic the octopus's ability to change colour and texture could be used in solar cells and other energy-harvesting devices, improving efficiency, and reducing environmental impact.
Fashion and Design: The fashion industry could see a new era of clothing and accessories that change colour and texture, offering dynamic and personalised fashion experiences.

The Future of Camouflage Clothing

Inspired by the adaptive camouflage skills of the octopus, the concept of camouflage clothing is undergoing a revolutionary transformation.

Imagine a world where clothing can adapt its colour and pattern to match the surroundings, just like an octopus. This isn't just a futuristic fantasy; researchers are actively developing fabrics that mimic the octopus's ability to change its appearance. These materials use the same principles of light manipulation and texture alteration found in the octopus's skin.

Such advanced camouflage clothing could have a variety of applications, from haute couture pieces of catwalk runways right through to accessible high-street styling. Camouflage clothing offers the fashion industry an exciting way of creating dynamic designs that can change in an instant.

Equally, in the outdoor gear space it could provide hikers, bird watchers, and wildlife photographers with a new and previously unexperienced level of interaction with nature, allowing them to blend seamlessly into any natural environment.

Here are five innovations in the context of camouflage clothing:

Camouflage Clothing Innovations

Adaptive Camouflage Fabrics: Inspired by the octopus's ability to change colour and pattern, these fabrics can adapt to the photographer's environment, helping them blend seamlessly into natural settings for undisturbed wildlife photography.
Heat-Signature Reducing Clothing: Developed to minimise the thermal signature that animals can detect, this clothing helps photographers get closer to wildlife without being noticed.
UV-Reflective Camouflage: Some animals can see ultraviolet light. Fabrics treated to reflect UV light in patterns – in the same way that some plants do – are intended to help wildlife photographers blend into environments in a way that animals are far less likely to notice.
Scent-Masking Garments: Incorporating materials and technologies that mask human scent, will become essential garments for wildlife photographers who need to get close to animals with a strong sense of smell.
Lightweight, Multi-Environment Camo Gear: Offering versatility across different terrains and climates, this type of gear uses advanced materials for comfort, mobility, and effective camouflage when traversing diverse environments.

These examples illustrate how fashionistas and outdoor enthusiasts could leverage the concept of camouflage clothing.
