🪼 Gentle Giant off Cornwall!

Spotted this barrel jellyfish (Rhizostoma pulmo) drifting along the coast. They’re common in warmer waters but can be seen in UK seas, especially in summer when plankton blooms attract them.

Warmer oceans may be making sightings more frequent — a reminder that protecting our seas from pollution and climate change keeps marine life in balance.

Harmless to humans, vital for the ocean 🌊

Happy World Mangrove Day! 🌱
 
Mangrove forests — silent protectors of our coasts and oceans.

They protect shorelines from storms and erosion.

They store up to 5 times more carbon than tropical forests, helping to combat climate change.

They are nurseries for fish, crabs, and countless marine species, supporting ocean biodiversity and coastal communities.

They provide food, fuel, and sustainable livelihoods for many coastal communities around the world.

Sadly, mangroves are under threat due to deforestation, pollution, and urban development. Mangroves need protection and restoration. The health of our oceans — and our planet — depends on them.

Can you spot the stonefish? 👀

One of the ocean’s masters of camouflage — and also one of the most venomous fish in the world.

Stonefish lie completely still on the seafloor, blending perfectly with their surroundings until an unsuspecting fish or shrimp swims by. In a split second, they strike — opening their jaws and vacuuming up their prey faster than the blink of an eye.

Ghost nets are a global problem

These abandoned fishing nets drift through the ocean, trapping marine life, damaging reefs, and polluting our seas for decades.

In Crete, Giorgios and Ioanna from Salty Descents Dive Center are always on the lookout. When conditions allow, they carefully remove ghost nets to help protect the marine environment. 

Every net removed is a step toward healthier oceans.

Love for Puffins - and for the Ocean

Puffins spend most of their lives at sea, diving for fish and braving harsh ocean conditions. 

 But these iconic seabirds are now listed as Vulnerable. Their decline is driven by climate change, overfishing, and pollution—threats that affect all marine life, not just puffins. Protecting puffins means protecting the ocean. Their survival depends on healthy, balanced marine ecosystems.

 At Just One Ocean, we’re all about protecting marine life, and that includes puffins. Our puffin apparel lets you spark conversation about ocean conservation.

Small Change, Big Impact

It’s estimated that over 400 million tonnes of plastic are produced every year, and half of it is designed for single use. That waste ends up in our oceans, choking marine life and damaging the ecosystems we all depend on.

But there is another way. By choosing products made from natural, plastic-free materials, we can start to turn the tide on pollution.

This World Ocean Day, we’re making it easier to take that step.
