Turnstone
Also called the Ruddy Turnstone (Arenaria interpres), this was another first for me. There were many of these little birds on the seashore bulldozing the seaweed out of their way with their heads in search of invertebrates hiding underneath it.

When The Tide Goes Out
When the tide goes out to reveal shallow pools and masses of clumped seaweed it is time for the waders to come and feed.
This Little Egret (Egretta garzetta) does an odd little dance to agitate the water to stir up small fish and invertebrates on which it feeds.

Spot The Little Fishy
I believe these are Shanny (Lipophrys pholis), also called Blenny. As the tide pulled out it left these crystal clear pools of water and in them they teemed with these young fish which moved nimbly through the shallow water. They are so well adapted to their environment you would hardly notice them until they moved.

Underwater
I love how the sunlight sparkles and shimmers within the rippling movement of the waters on the coast. These are abstract worlds which I would like to glimpse more often than I do, full of the richness of life and wonder. These images feature what I believe is a seaweed called Gutweed (Ulva intestinalis).

Two Gapers
I have shown the two gaper shells on one post to illustrate how different they are, beginning with the Sand Gaper above.
Sand Gaper (Mya arenaria)
A large and robust bivalve, the shell is oval in shape, the anterior end rounded, the posterior end more pointed. It has concentric ridges and is off-white, grey or light brown in colour. Shell length 15cm.
The Sand Gaper burrows to a depth of 50cm into mud and sandflats, where it filters organic matter from sea water. It is often found in estuaries, and is widespread and locally common.
Blunt Gaper (Mya truncata)
A thick-shelled, robust bivalve, rectangular in shape with a truncate posterior margin. It also has numerous concentric lines and is off-white in colour. Shell length up to 70mm.
It is commonly found in estuaries where it buries itself to a fair depth. Widespread and locally common, especially on the east coast of Britain.

Baltic Tellin
Macoma balthica
The shell is a rounded-oval, although the posterior more angled. The colour is variable from pink to purple, yellow and white. Width 25mm.
It is found on the lower shore in muddy sand, and also in estuaries. Common and widespread.

Peppery Furrow
Scrobicularia plana
The shell has numerous fine, concentric rings and grooves. It is dirty white, yellowish or greyish in colour, and is flat, thin and delicate in form. Length 6.5cm.
It is found in sheltered, brackish habitats, like estuaries and muddy shores where it burrows up to 20cm, leaving behind a star-shaped tell-tale impression on the surface. It is a deposit-feeder, and when the inhalant siphon is extended it is often eaten by crabs, fish and wading birds, but it is regrown fairly quickly. Common and widespread all around the UK.

Striped Venus Clam
Chamelea gallina
The colour of the shell is pale cream or yellowish, usually marked with three prominent radiating brown bands. It is fairly thick and has fine concentric ridges. Length 4cm.
It is found buried in the lower shore to sublittoral, and it can live up to 10 years. Common and widespread on all coasts, except the south-east coast of England.

Banded Wedge Shell
Donax vittatus
This mollusc has a shiny white to yellow, purple or greyish-brown slender wedge-shaped shell. Growth stages show as pale bands. The inner surfaces are tinted white, purple, yellow or orange. Length up to 38mm.
Found on the middle to lower shore where it burrows into coarse sand and lives just below the surface. The Banded Wedge Shell is a filter feeder, and when the tide is in it extracts food particles from the water via a syphon. Common and widespread on all British and Irish coasts, but less common further north on Scottish coastlines.

Coral Weed
Corallina officinalis
This seaweed has a feathery appearance with its regular, opposing branched pattern. It varies in colour due to age and lighting conditions. The deeper it is it grows dark pink. It has a pink, disc-shaped encrusting holdfast which helps it anchor itself to rocks, shells or other larger seaweeds. It can grow up to 12cm in height.
It is typically found lining the edges of mid-shore rock pools. It is common and widespread.

Bean Solen
Pharus legumen
The shell is elongate, thin and brittle. There are numerous fine concentric lines, with a group of fine radiating striae. It is white or light brown, light olive or yellow. The hinge and ligament is positioned about a third of the way along the length of the mollusc. Length up to 130mm.
It burrows deeply in fine to medium course sands in the lower shore and shallow sublittoral. Found on the south-west coasts of England, Wales and Ireland.

Common Limpet
Patella vulgata
Have you ever wondered what the underside of a limpet looked like? Note the large muscular foot, the relatively small mouth above, and the tentacles either side.
The Common Limpet has an ashen-grey or greenish-blue shell, sometimes with a yellow tint, and with radiating ridges. It is conical with an almost central apex. The shell is often covered in barnacles. The sole of the foot is yellowish or orange-brownish with a green tinge. Shell length 6cm. They are fairly long-lived, up to 15 years.
It inhabits the intertidal zone, clinging tightly to rocks along the shore or in rock pools, and with its thick shell it is able to withstand the pounding ocean waves, exposure to drying out, and attacks from birds or fish. It grazes on algae growing on the rocks beneath the water. It is not ‘stuck’ in one position as it may always appear to be, but follows a mucous trail as it feeds and finds it way back. Scarring maybe evident on the substrate where it has ground it down to get the perfect fit. Common and widespread around the British coasts.

Common Mussel
Mytilus edulis
Also called the ‘Blue Mussel’, the shells are dark brown, blue-black, or purple in colour. Shell length up to 10cm.
It is found middle to lower shore, and attaches itself to rocks via byssus threads. It will also find crevices in the rocks, or attach themselves to manmade structures like piers and harbour walls. They can form large beds up to 6 layers thick and covering many square kilometres. Mussels are filter feeders of plankton, pumping large amounts of water through their bodies to extract the food.
Very common and widespread all around the British coast.
This is an edible marine mussel which has been harvested by humans for centuries. They are a rich source of protein, and are very important to the marine life ecosystem.

Prasiola stipitata
This is a small, dark green lettuce-like algae when wet, which forms flaky coatings over rocks and boulders. Length 1cm.
It grows on rocks and stones in the splash zone, mostly frequented by seabirds which drop their faeces from which it gets its nitrates to flourish. A common and widespread species, but mainly seen in spring and early summer.

Purple Laver
Porphyra umbilicalis
Greenish in colour when young, but becoming purple-red as it matures, and is very resistant to drying out and the action of the waves. It forms thin, delicate sheets which cling to rocks and has a polythene-like texture. Width 20cm.
Found attached to rocks in sandy habitats. Abundant and widespread on rocky shores throughout.
Purple Laver is used to make laverbread in Wales, which is a traditional Welsh recipe.

Egg Wrack Wool
Polysiphonia lanosa
A brownish-red seaweed which is tufted and made up of branching filaments which gives it a wool-like consistancy. Length 70cm.
Found middle to low shore, and grows mainly on Egg Wrack (Ascophyllum nodosum) for physical support, known as an epiphyte. It makes use of the hosts buoyancy at high tide so it will gain more sunlight. Common and widespread throughout the British coastline.
