Gorgeous little cove, the white sands and views reminding me very much of a Hebridean island beach. St Brides Haven is one of best spots for snorkeling in Pembrokeshire, if not Wales – head out for the reef protecting the cove for superb snorkeling in a kelp forest with lobsters, crabs, wrasse, pollack and dogfish and if you’re lucky a seal. You’ll also enjoy yourself investigating the sandstone rock-pools around the cove, including gem and dahlia anemones.

In September 1988, the largest and heaviest ever recorded leatherback turtle in the world was washed ashore on Harlech beach, Gwynedd, after being drowned from being trapped by fishing lines. It was approximately 100 years old when it died. It measured almost 3m in length and weighed 914 kilos. It is today on display at the National Museum in Cardiff.
Approximately half the world’s population of Manx shearwaters nest on Skomer and its “sister” island of Skokholm with an estimated total of 310,000 pairs on Skomer itself and 40,000 pairs on Skokholm, making this the world’s most important breeding site for the species. The birds usually nest in rabbit burrows. The two islands are also home to the largest colony of puffins in southern Britain (10,000 breeding pairs), many likewise nesting in the burrows created by the large population of rabbits.
BBC Radio 4’s Living World visits Skomer Island off the south east coast of Wales and home to thousands of seabirds.
There are 25,000 guillemots packed together on the cliffs, no other bird breeds in such close proximity to its neighbours. Fights and squabbles constantly break out, but friendships and pair-bonding are very strong. They keep the same mate for life and produce one chick a year. The fledgling has to leap from the sheer cliff face into the sea below to find its dad, surrounded by thousands of others, and try to avoid being eaten by predatory gulls. Each year each guillemot pair comes back to exactly the same place on the cliff ledge and they defend it vigorously.
In the early decades of the 20th Century there were 100,000 guillemots on Skomer but numbers plummeted to just 2000 after the second world war, probably due to oil pollution in the sea. Now numbers are slowly recovering but the increase in storms may be a problem for them in the future. Listen

Located 11 miles of the coast of Pembrokeshire, Grassholm is home to more than 39,000 breeding pairs of Gannet, representing around 10 percent of the world population – the third largest Atlantic gannet colony in the UK (behind St Kilda and Bass Rock). The island is also the westernmost point in Wales.
Ivell’s sea anemone (Edwardsia ivelli) is the only know endemic animal to be known to have gone extinct (probably) in Britain in modern times. It has not been found since 1983 despite detailed searches at its only known site, Widewater Lagoon in West Sussex.
From Few and Far Between: On The Trail of Britain’s Rarest Animals by Charlie Elder. An excellent and amusing read,
“It was the summer of 1972, and Oxford zoology graduate Richard Ivell had risen early, eager to press on with his research. He stepped into his backyard to sort through several buckets of mud and brine collected the day before. These thick, stinking sections of sediment dug from Widewater Lagoon in West Sussex provided raw material for his master’s thesis on the ecology of brackish environments. Sandwiched between land and open sea, lagoons are vulnerable and yet hostile habitats, where fluctuating temperature and salinity test life forms to the limit. Landlocked Widewater, a shallow stretch of water running for nearly a mile next to the A259 near Worthing, provided the perfect place to study. Bordered by the back gardens of houses to the north and beach huts to the south, the narrow basin is kept topped up by rainfall and by the sea that percolates through its shingle banks during high tides. Various kinds of prawns and cockles live within its confines, and some of these creatures would have been scooped up in the samples Richard had collected just a couple of metres out from the seaward edge. The mud had settled overnight within the buckets, each surface a dark brown disc submerged under a lens of clear salt water. In the quiet, life had stirred.
Forty years later, the memory is still vivid, as Professor Ivell told me on the phone from the animal biology institute in Germany where he now works. Peering over the rim of one of the containers, he couldn’t believe what he saw. ‘In the stillness, small anemones had emerged and their lightly banded tentacles were spread out flat against the sediment. The thing I remember is how beautiful they were, and how fragile, like tiny flowers in a desert. It was quite amazing to see.’Unable to identify the small burrowing species, he showed a colleague at Oxford University, Richard Manuel. If the catchphrase among Anthozoa taxonomists is ‘know thine anemone’, then Dick was the person to ask. An expert in such marine life, he realised that these specimens, no more than a couple of centimetres long, buff coloured with twelve transparent tentacles, the outer nine marked with cream bands, were new to science.”
The whalebone arch in Whitby commemorates the Yorkshire town’s historic link with the whaling industry. The bones are from a Bowhead whale which was killed under license by Alaskan Inuits, and unveiled by Miss Alaska in 2003. The presence of whales in Britain
In 1753 the first whaling ship set sail to Greenland and by 1795 Whitby had become a major whaling port. The most successful year was 1814 when eight ships caught 172 whales, and the whaler, the Resolution’s catch produced 230 tons of oil. The carcases yielded 42 tons of whale bone used for ‘stays’ which were used in the corsetry trade until changes in fashion made them redundant. Blubber was boiled to produce oil for use in lamps in four oil houses on the harbourside. Oil was used for street lighting until the spread of gas lighting reduced demand and the Whitby Whale Oil and Gas Company changed into the Whitby Coal and Gas Company. As the market for whale products fell, catches became too small to be economic and by 1831 only whaling ship, the Phoenix, remained.
The rocky headland of Hella Point near Land’s End offers great views of basking sharks during the summer months. The Cornwall Wildlife Trust Basking Shark Project runs sightings here from June to the end of August. For instance in 2010, more than 600 basking sharks were sighted here, mainly in June along with grey seals, sun fish, fin and minke whales and common, bottlenose and risso dolphins.
Chanonry Point on the Black Isle is famous as one of the best places in Europe for watching dolphins from the comfort of land. These bottlenose dolphins (Tursiops truncatus) can often close to the shore, especially after low tide, when they come in to fish in the strong currents. In fact BBC wildlife presenter Simon King has described Scotland as “one of the best land-based dolphin watching hot spots in the world”. It is also a top spot for seal watching. Note the nearby Dolphin and Seal Centre in North Kessock is now closed as of 2015.
While bottlenose dolphins can be seen off the point throughout the year, the chances of seeing them increase when their food supply increases, the peak times being when salmon are returning towards the two main rivers (the Ness and Beauly) which feed into the Moray Firth. The salmon come in with the tidal current which, once the tide starts to come in, can be extreme. If planning a trip, find tide details and pick days with midday low tides with the largest difference between low and high tide (spring tides, avoid the neap tides). An unofficial “jungle telegraph” system operates round the Rosemarkie campsite and point in June and on into August with details of the latest sightings only a brief conversation away. The University of Aberdeen operates a more formal range of surveys throughout the year from their field station based just along the coast at Cromarty, supported by funds from the Whale and Dolphin Conservation Society. While the Point is regarded by many people as the best place to watch the dolphins from land, licenced boat trips do run from Cromarty and Avoch.
Nessie the Black-browed Albatross which took up residence on the gannet island colony of Sula Sgeir, 8,000 miles away from his natural breeding grounds. The bird is thought to have first arrived in Scotland after being blown off course in the South Atlantic in 1967. For many years it was the only known albatross in the northern hemisphere. BBC News

In 2010, a seal was spotted climbing over a dike at Fen Drayton lakes in Cambridgeshire, more than 50 miles from the coast at King’s Lynn in Norfolk, where the seal is thought to have entered the river Great Ouse from where is made its way upriver during floods. It manages to get into the field, now a mere, with swollen water from the lake inside. More from BBC: Seal ‘swims 50 miles into lake’
