Celebration to spotlight magical and mysterious wildlife of UK seas

From honeycomb worms to solar powered sea slugs, this summer’s National Marine Week from Kent Wildlife Trust will shine a light on some of the lesser-known creatures and plants found in UK seas.

The annual seaside celebration aims to inspire a new generation of marine conservationists and volunteers through rock pool rambles, snorkel trails, beach cleans and other events that help nature, around the British Isles. National Marine Week takes place from Saturday 22nd July to Sunday 6th August – spanning a fortnight due to varying tidal conditions around the UK.

UK seas are home to over 330 species of fish, 28 cetaceans, seagrasses, seaweeds and living reefs. The marine environment is also under huge pressure from damaging fishing practices, development at sea and pollution from farming, sewage and plastic.

Sherece Thompson, Coastal and Marine Ecologist for Kent Wildlife Trust says:

“From sea snails to seagrass meadows, our seas are awash with fascinating creatures, habitats, and plants. This year’s National Marine Week reminds us of the great diversity around our shores and why it is so important we look after our seas for people, wildlife and climate.

“We are encouraging young people to join events and find out more about the work being done to protect our shores and seas. From backing campaigns to beach cleans, there are so many ways to get involved.

“It is critical that at least 30% of UK seas are given the highest level of environmental protection by the end of this decade. Doing this will help wildlife recover with enormous benefits for fishing, as well as ensuring vast amounts of carbon remains stored in natural habitats such as saltmarsh, mud, and seagrass. Better protections for our seas will mean more wildlife, and that helps everyone.”

Some of the lesser-known species found in UK seas include:

• Brittlestars: Related to starfish with five long, flexible arms. Brittle in name, brittle in nature, they shed parts of their arms if they are disturbed or threatened. Brittlestars are found around the UK in rook pools and down to 85 metres deep. They gather in groups, with numbers of 2,000 recorded per square metre.
• Risso’s dolpin: Found in deep offshore waters, they are whiter than other dolphins with large, blunt heads and stocky bodies. The scratches on their bodies are the result of rough behaviour from fighting and catching prey.
• Undulate ray: A species of skate that buries itself in sand and mud up to depths of 200 metres, though more commonly found in shallower waters. They can live for more than 20 years.
• Sea hare: A marine snail that looks like a sea slug but has an internal shell. They can be found in shallow waters and rockpools and, like sea slugs, are hermaphrodites with an individual acting as both male and female. Sea hares feed on seaweed, which is thought to determine its colour. Green sea hares eat green seaweed and maroon sea hares eat red seaweed.
• Gannets: The largest of our sea birds with a six-foot wingspan, a creamy-yellow head and a long dagger-like bill. They can be seen circling in groups above the sea looking for fish before plummeting head-first into the water.
