Marine

There's another world waiting beneath the waves. Seals weave in and out of sunlit kelp forests, cuttlefish flash all the colours of the rainbow, starfish graze along the muddy seabed and sharks slip through the open water.

Not just water

The sea can seem like just a huge expanse of water – vast, deep and maybe a little scary. But a huge variety of habitats can be found here. Close to shore, rocky reefs create rockpools that teem with anemones and starfish, while further out to sea, deep-water corals provide nursery sites for many of our commercial fishes such as cod.

Kelp forests support numerous species from tiny plankton to large fish, and living reefs (made entirely of organisms like mussels or tubeworms) provide food and shelter for marine wildlife. In the shallows, seahorses and bass hide among underwater meadows of seagrass.

Deep-sea mud plains may look barren and lifeless, but they are home to all kinds of sea life like bristleworms, spider crabs and lobsters. Shallow mudflats are a feeding ground for waterbirds at low tide, and sand and gravel beds are important for crustaceans like shrimps, and for spawning fish, which burrow into the seabed for protection.

Seas are under threat

As a result of its richness, our marine environment is under threat. Overexploitation of fish stocks is causing the decline of many once-familiar species. Pollution from sewage discharge, oil spills and nutrient run-off is extremely toxic to sea life, while physical disturbance from dredging, mobile fishing gear, boat anchoring and coastal development are also taking their toll on marine habitats.

Species in Marine habitats in Kent

Orca

Orca, sometimes known as ‘killer whales’, are unmistakable with their black and white markings. Although we do have a small group of orca who live in British waters, you would be lucky to see them!

Moon jellyfish

The moon jelly is the most common jellyfish in UK seas, often washing up on our beaches. No need to worry though - it doesn't sting humans.

Edible periwinkle

Edible periwinkles are a common sight when rockpooling and can be found in huge numbers on the shore.

Lesser weever fish

One of the only venomous fish to be found in British waters, the lesser weever fish is certainly one to watch out for!

Common seal

The smaller of our two UK seal species, common seals are also known as harbour seals. Despite being called "Common", they are actually less common than grey seals!

Shore crab

This crab is common around all of the UK. If you've ever been rockpooling or crabbing, it's probably the shore crab that you've met.

Humpback whale

The humpback whale is making a comeback, with more and more individuals being seen in UK seas every year. They are well known for their acrobatic behaviour - so don't be surprised to see them breach clear of the water!

Our reserves with marine habitats

Sandwich and Pegwell Bay

Listen to the rolling waves on the sand and shingle, breathe in the saline scents of the saltmarsh, and watch the wonderful wildlife this very important and sensitive National Nature Reserve has to offer.

Habitat

Meadows of seagrass spread across the seabed, their dense green leaves sheltering a wealth of wildlife including our two native species of seahorse.
