A Day in the Life of a Limpet At first glance, it looks like nothing more than a rough cone glued to a rock.  But along the wave-battered shores of Britain, the limpet lives a life of timing, endurance and quiet precision. Morning: Clamped to the Rock As the tide retreats from a rocky stretch of coastline in Cornwall, a Common Limpet is left exposed to the open air.  The sea has drained away, revealing barnacles, seaweed and scattered pools. But the limpet remains firmly attached to its chosen patch of rock. Limpets have a unique tongue known as a radula, and its tiny teeth literally scrapes algae from the rocks.  In fact their teeth are the strongest biological material known to man. The teeth of the Common Limpet contain densely packed mineral fibres called goethite.  In a widely cited 2015 study, researchers measured their tensile strength at around 3–6.5 gigapascals (GPa), which exceeded previous measurements for spider silk and many other natural materials.

Cornwall’s rocky shores are like Nature’s treasure chests. When the tide slips away, it leaves behind hundreds of tiny, temporary aquariums — rockpools — each one packed with life tough enough to survive waves, sun, rain, and curious humans.  If you know where (and how) to look, a single pool can reveal an entire miniature world. Here’s what you might discover when rockpooling along the Cornish coast: A Living Jigsaw of Colour and Texture At first glance, a rockpool may look still — just seawater trapped in stone.  Look closer and everything changes.  Seaweeds sway like underwater forests, shadows dart between rocks, and the pool itself feels alive. Cornwall’s Atlantic-facing coastline creates especially rich rockpools thanks to clean water, strong tides, and a mix of exposed and sheltered shores. Crabs, the Sideways Scavengers Crabs are often the first thing you’ll spot. Common shore crabs hide under rocks, ready to scuttle away at lightning speed. Green crabs blend perf...

Starfish: Extraordinary Survivors of the World’s Oceans Starfish, also known as sea stars, are among the most recognisable and fascinating creatures found in oceans across the globe.  With their striking shapes, vibrant colours, and unusual biology, starfish capture the imagination of beachgoers, divers, and marine scientists alike.  Found from shallow rockpools to the deepest ocean floors, these remarkable animals are perfectly adapted to life in the sea. What Are Starfish? Despite their name, starfish are not fish.  They belong to a group of marine animals called echinoderms, meaning 'spiny skin' , which also includes sea urchins and sea cucumbers.  Starfish are invertebrates, meaning they have no backbone, and are known for their distinctive radial symmetry—most commonly with five arms, though some species have many more. A starfish's skeleton is on the inside of its body and is made of small calcium carbonate plates called ossicles. These plates create the tough,...

Coastal Rockpools in Cornwall, UK: Tiny Worlds on the Edge of the Atlantic Cornwall’s rugged coastline is famous for its dramatic cliffs, golden beaches, and rolling Atlantic waves.  But at low tide, another world is revealed—coastal rockpools, packed with life and colour. These shallow pools, left behind as the sea retreats, are miniature ecosystems that offer a fascinating glimpse into marine life along the Cornish coast. What Are Rockpools? Rockpools are natural basins in rocky shorelines that trap seawater when the tide goes out.  A tide pool can be underwater and connected to the ocean at high tide, then become an isolated pool at low tide.  Organisms living there must cope with: • Rapid temperature changes • Fluctuating salinity (salt concentration) • Variable oxygen levels • Wave impact during high tide • Exposure to air and predators during low tide The intertidal zone is typically divided into several bands: Spray zone Rarely submerged Contains lichens, hardy sna...
