We have just spent another fantastic weekend surveying and collecting eDNA samples in St Ives Bay with some wonderful volunteers. This is the third year of collecting data and we are starting to understand the four distinct areas we are looking at. Each location has a different role within the ecosystem, from rich rocky reef habitats that serve as fish nurseries for numerous species, to sand and mud substrates that look desolate but have an incredible biodiversity. On top of that we had a real treat on the journey back to Newquay Harbour when a huge pod (estimate around 80) of Common Dolphins joining hundreds of Gannets feeding on a bait ball, and then two Minke Whales joined the party. Marine research in the UK doesn't get much better than this.

🐙 A master of disguise in action. Octopuses are among the most remarkable animals in the ocean, able to change both their colour and skin texture in an instant. As they move across the reef, they blend seamlessly with their surroundings to avoid predators, ambush prey, and conserve energy. Octopuses play a vital role in healthy marine ecosystems. As intelligent mid-level predators, they help regulate populations of crabs, molluscs, and other invertebrates, maintaining the natural balance of reef communities. They are also an important food source for sharks, groupers, moray eels, and many other marine animals, making them a key link in the ocean food web. #ProtectOurOceans #oceanconservation #healthyecosystems #justoneocean

Hawksbill turtles are often seen nibbling around coral reefs—but they’re not actually eating the coral itself. Their favorite food is sponges, which compete with corals for space. Hawksbills help coral reefs stay healthy and diverse by keeping sponge populations in check. It's one of the many ways these critically endangered turtles play a vital role in ocean ecosystems. #hawksbillturtles #oceanecosystems #IUCN #critacallyendangered

Some powerful opening statements at the official opening of the 11th Our Ocean conference particularly from Governor of Mombasa and Sec. John Kerry. "We have no excuses. The situation is due to our greed and ignorance." "It is not a future problem, it is a present reality." #OOC11 #blueeconomy

Fast and powerful, the Great Barracuda plays a crucial role in keeping marine ecosystems healthy. As a top predator, it helps maintain balance by controlling fish populations, supporting biodiversity, and contributing to resilient reefs. When predators like barracudas thrive the entire ecosystem benefit. Their presence is a sign of a functioning food web and a resilient marine environment. Protecting species at the top of the food chain helps safeguard the countless plants and animals that live below them. #JustOneOcean #GreatBarracuda #OceanConservation #MarineLife #HealthyOceans

To take part, choose the day that works for you between 23-31 May, head to your local rocky shore, explore the rock pools, and record what you find using the iNaturalist app. For more information and to register, visit: https://www.therockpoolproject.co.uk/national-bioblitz

A very happy birthday to Sir David Attenborough. A man who has dedicated his life to preserving the natural world.

Isle of Wight Ultra Challenge 🏃‍♂️ Beautiful coastal scenery, fresh sea air, a brilliantly organized event, and a beautiful route. Photos also capture the striking signs of coastal erosion along the way. The weather didn’t quite cooperate the entire weekend —but that just makes the challenge even more memorable. 🌧️ #Ultrachallenge #IsleOfWight #CoastalScenery #CoastalErosion

Mobula rays are known for their dramatic breaches—leaping clear out of the water and landing with a loud splash. An incredible sight, but scientists are still figuring out exactly why they do it. Some of the leading ideas: • Communication • Parasite removal • Courtship behavior • Social or play behavior While the behavior is still a mystery, the threats they face are not. Mobula rays are vulnerable to overfishing, bycatch, and habitat pressures. Protecting them helps maintain healthy ocean ecosystems. Thanks you Barna at @encounters_tours for the wonderful images. #MobulaRays #OceanConservation #MarineLife
