Turnstone

Turnstone Arenaria interpres

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.

Underwater

Gutweed Ulva intestinalis

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).

Cunning Crow

Jackdaw Corvus monedula

This Jackdaw (Corvus monedula) wasn’t shy at all when it came and landed on a seawall above the cliffs close by. It was so close you could almost reach out and touch it. It came even closer, and I thought perhaps it was expecting a food handout, but it had already got its beady eye on a crisp some passerby had dropped on the ground. As nimbly as can be it jumped off the wall, picked up the crisp in its beak and swooped off over the cliffs with it.

Jackdaw Corvus monedula

I cease to be amazed how adaptable these crows have become by the sea. I have even seen them follow the seagulls out at low tide to go and search for crabs and other invertebrates between the exposed rocks and the seaweed.

Jackdaw Corvus monedula

These intelligent birds are the smallest member of the crow family, and they are so devoted that they will form strong bonds with their mates and will pair up for life.

Herring Gull

Larus argentatus

Herring Gull Larus argentatus

These are the blighters that will swoop down and steal your ice cream or fish and chips whilst on the beach or the seafront. A few years ago I was sitting on a pebble beach and was about to tuck into a nice custard tart when one dive bombed me from behind and snatched the lot from my grasp in its beak.

Herring Gull Larus argentatus

This one landed on the roof just outside my hotel window. When I was a young lad I only used to see these beside the seaside, but now they fly overhead and have even landed on my garage roof here in the West Midlands where I am completely landlocked. Many have adapted well to a life inland, living off the rubbish we leave in our wake.

Herring Gull Larus argentatus

Yes despite their adaptability they are on the RSPB Red Status list here due to a moderate decline in numbers over the last 25 years. I have to say I do have a soft spot for them, despite the reputation they get sometimes. Yes they are scavengers and will virtually eat anything, and will attack small birds and other animals, yet their piercing cries and their streamlined forms as they soar aloft in the high blue yonder is alway quite something to experience.

Coral Weed

Corallina officinalis

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.

Common Limpet

Patella vulgata

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.

Common Limpet (Patella vulgata)

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

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.

Common Mussel (Mytilus edulis)

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.

Common Mussel (Mytilus edulis)

Very common and widespread all around the British coast.

Common Mussel (Mytilus edulis)

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.

Oystercatcher

Haematopus ostralegus

Oystercatcher (Haematopus ostralegus)

This is one of the larger waders, and certainly one of the most distinctive with its black and white body, dazzling red-eye and long, vivid orange-red bill. It has short, pale pink legs, and long and  broad white wingbars with a white ‘V’ on its back can be seen when in flight. In the winter it has a white-collar and a dark-tipped bill. Length 40 to 45cm.

Oystercatcher (Haematopus ostralegus)

They feed in large groups probing sand and mud with their long bills for marine worms and molluscs, or they prise shellfish from rocks along with seaweed. They will also eat earthworms and other invertebrates when venturing inland if food is in short supply on the coast. They breed on almost all UK coasts, and within the past 50 years further inland. They form a shallow scrape in shingle or sand, often amongst rocks or grassy tussocks where they lay 2 or 3 eggs in 1 brood from April to July. They can live for up to 15 years.

Seen all year round, and they often occur in enormous tight flocks where they may dominate whole estuaries. Also seen on sandy, muddy, and rocky beaches, grassy islands, shingle or riverside grassland, and grassy fields. They are common and widespread, occurring on almost all UK coasts. Most UK birds spend the winter on the coast, where on the east coast their numbers maybe increased by birds from Norway. The RSPB have given them an amber status due to their vulnerability of the over-fishing of cockle beds which they rely on for food.

A very noisey bird, especially as they form tightly packed flocks, producing penetrating kleep sounds.

Catch The Runner!

Redshank (Tringa totanus)

Redshank (Tringa totanus)

The Redshank has a straight, black-tipped red bill and red legs, as the common name suggests. It has a marbled-brown back and a white, black-spotted underbelly. The males and females are similar, and the juveniles have yellow-brown legs. Length 27 to 29cm.

Redshank (Tringa totanus)

To feed they probe mud and sand with their medium-sized bill for molluscs, worms and crustaceans. The nest in a hollow in the ground often with a grass canopy formed above it where the female lays 4 eggs in 1 brood from April to July. They can live for up to 10 years.

They breed in saltmarshes, wet pastures, marshes and near lakes, but during the winter on the coast on estuaries and lagoons. They maybe observed all year round.

Widespread and frequent on many coastlines, with up to almost 40,000 breeding UK pairs, and 120,000 wintering birds in the UK. The RSPB has given the Redshank an amber status due to declining numbers due to loss of salt-marsh habitats, and in areas where farmland is drained.

Common Prawn

Palaemon serratus

Common Prawn (Palaemon serratus)

The Common Prawn has large eyes and a translucent body with yellow, brown or reddish stripes. It has an elongate body with a fan-shaped telson (last segment, or appendage of the last segment of the abdomen). It has a large upturned rostrum with 6-7 dorsal teeth and 4-5 ventral teeth. The first two pairs of walking legs bear claws, and have red, blue and yellowish banding. It can move very quickly, and is a very inquisitive creature. Length up to 11cm.

It is a ominvore and it will eat virtually anything from dead animal life, to hunting other invertebrates, and to consuming plant material.

Found on the upper to lower shore, in rockpools, amongst seaweeds and under rocks and boulders. Our commonest prawn, it is widespread throughout. Prawns are a valuable food source, and are of extreme commercial interest.

American Slipper Limpet

Crepidula fornicata

American Slipper Limpet (Crepidula fornicata)

This limpet has a humped, smooth shell with variegation in colour, usually pinkish, orangey, cream or purplish. It has a fairly thick shell with a shelf on the underside, which resembles a slipper. Shell length 5cm. Shell height 2.5cm.

American Slipper Limpet (Crepidula fornicata)

It is found on the lower shore, attached to rocks and other shells, and they form stacks of up to ten individuals or more. They begin life as males, and then change progressively to become females. An introduced species from north-east America in 1887, the Slipper Limpet is quite an invasive species which competes with native oysters for space and food, and is also a threat to Common Mussel beds. Common and widespread.

Dog Whelk

Nucella lapillus

The Dog Whelk’s shell is variable in colour, from white to dark brown, yellow or banded. Thick-shelled, it is broadly conical bearing spiral ridges with a short spire. Shell height 3 to 5cm.

It is a fierce predator of mussels, barnacles and other molluscs. It bores a hole into the prey’s shell using its radula. Its digestive juices dissolve the prey and it sucks it up with its proboscis. It produces yellow egg capsules which are fixed in clusters under rocks. It can live for up to 10 years.

Found in all types of rocky shores from the middle shore downwards, on rocks, under overhangs and in crevices. Common and widespread.

Photographs taken April 2014, Llanduno, Wales, and August 2015, Meadfoot Beach, Torquay, Devon.

 

Master Builders

Sir Chiton

Grey Chiton (Lepidochitona cinerea)

I enjoy being nosy in rock pools when I visit the coast, and when I first set eyes on one of these I had no idea what it was, so I had to look it up. It is a mollusc, and this particular species has only been around for about 500 million years, and belong to one of the oldest animal groups on earth. And in all that time it has hardly changed at all.

Chitons are also called ‘Sea Cradles or ‘Coat-of-Mail Shells’ because they look like interlinked chain mail. At first glance they may look like tiny fossils, but they are living creatures. The shell is composed of eight arched plates which fit closely together. They cling to the rock surface by a large muscular foot and the form of the shell helps them especially on uneven surfaces. The body is oval-shaped, and chitons can curl up into balls like woodlice, their hardened shells helping to protect them. The colours are variable with alternating light and dark bands. They can grow up to 28mm in length.

They feed by using a radula, a kind of mollusc tongue which they use to scrape off and eat microscopic algae growing on the surface of the rocks.

The Grey Chiton can be found on the lower shore affixed to rocks in rock pools. This is the most common and widespread chiton to be found in the intertidal zone.
