#MarineWildlife - Whale watchers on Slea Head were treated to a special sight earlier this week with the surprise appearance of the killer whale known as John Coe, as the Irish Examiner reports.

Landscape photographer Richard Creagh was among the lucky few on Monday (27 June) to spot the orca known by the distinctive notch on his dorsal fin – though in more recent times he's also lost a chunk of his tail fluke, most likely to a shark bite.

Creagh, a keen marine wildlife watcher for the last 10 years, said: "Up to now killer whales had always eluded me but today I got to add them to my list, and what a sight it was! I’m still buzzing!"

John Coe's unique orca pod are regular visitors to Irish waters, though he himself was last spotted close to our shores almost three years ago at the Inishkeas in Co Mayo, according to the Irish Whale and Dolphin Group – which is asking the public to watch the seas for any more sightings of the senior cetacean.

#DopeyDick - A killer whale who gained notoriety after swimming up the River Foyle in the late 1970s has been rediscovered enjoying his retirement off the west coast of Scotland, as the Derry Journal reports.

It's more than 38 years since the orca astounded the people of Derry by swimming up the estuary and hanging around the city for a number of days, earning the name 'Dopey Dick' for shrugging off attempts to lure him back to the safety of open water.

His whereabouts thereafter were unknown -- till cetacean experts with the Hebridean Whale and Dolphin Trust compared old photographs of his Derry visit with more recent images of the unique orca community that makes its home off the western Scottish coast, and identified a positive match.

Comet, as the orca is properly known, is estimated to be at least 58 years old, double the usual life expectancy for the species.

But that's not so surprising for the orca pod referred to as the 'West Coast Community', which has been a regular visitor to Irish waters over the years, and has interested marine wildlife specialists for decades due to its "evolutionary significant" qualities.

Sadly that group's numbers have been dwindling, with fellow orca Lulu becoming the latest victim after its believed she was entangled in fishing gear early this year, as previously reported on Afloat.ie.

#MarineWildlife - The killer whale found beached on a Scottish island last weekend likely died after getting entangled in fishing gear for days, say experts.

As previously reported on Afloat.ie, the orca known as Lulu to researchers, who have been tracking her unique pod since the early 1990s, was discovered on the island of Tiree in the Inner Hebrides last Sunday 3 January.

Lulu's "evolutionary significant" group has been under threat for years due to the absence of calves among its number since scientists began monitoring them around the Scottish and north Irish coasts.

But according to The Press and Journal, Lulu's death was not down to natural causes – with a post-mortem report from experts at the Scottish Marine Animal Strandings Scheme claiming "convincing evidence that she had become chronically entangled" in fishing gear, with deep wounds consistent with a rope wrapping around her tail.

“There were no ropes or gear left on the carcass," said the scientists in a statement. "We’re assuming all this from the lesions we found on her body, so we don’t know if this was due to active fishing gear, abandoned or ‘ghost’ gear, or other marine debris."

#MarineWildlife - One of the last remaining members of a unique pod of killer whales has been found dead on a Scottish island.

As STV News reports, the orca known as Lulu to marine researchers was found beached on the island of Tiree in the Inner Hebrides on Scotland's west coast on Sunday 3 January.

Like John Doe, who is believed to have survived an altercation with a shark a year ago, Lulu was one of a familiar family of orcas that's regularly seen off Scotland and even as far west as the Donegal coast.

It's a pod that's piqued the interest of marine science due to its genetic distinctiveness from other orcas in the North Atlantic, as previously reported on Afloat.ie.

But the "evolutionary significant" group's numbers have been dwindling in recent years due to the absence of calves since scientists started tracking them more than two decades ago.

"It is particularly sad to know that another one of these killer whales, unique to the British and Irish Isles, has died," said the Hebridean Whale and Dolphin Trust. "There may be as few as eight individuals remaining in this population."

#MarineWildlife - A seal pup was lunch for a killer whale that's been attracting onlookers to Wales' Irish Sea coast in recent days.

As the Carmarthen Journal reports, the orca was first sighted of Mwnt, north of Cardigan, over the summer, but has since been spotted further down the coast near Fishguard - believed to be attracted by a boom in the local seal population.

It marks a rare appearance for the species in the Irish Sea, as they're more commonly spotted in Scottish waters and off Ireland's North Coast.

And it comes not long after another rare sight in the form of a pod of Risso's dolphins sighted near Anglesey in north Wales earlier this month - with experts telling BBC News that it may be one of the largest such pods ever recorded in Welsh waters.

In other marine mammal news, The Irish Times has video of a seal who appears to have taken a liking to Dublin city centre, swimming many kilometres up the Liffey from the usual Dublin Bay haunts.

#MarineWildlife - Make-A-Wish Ireland brought six-year-old Ondrej Byrtusova's dreams to life when they whisked him and his family away to Florida to train a killer whale, as the Irish Independent reports.

Ondrej – who was born with Hypoplastic Left-Heart Syndrome – was given the opportunity by the Irish charity to teach a few tricks to orca Malia, who is described as "sweet and playful".

“It was the nicest moment ever when I saw my son so happy and joyful,” said his mother Vlasta. “I am very proud of him that he did it.

"He was absolutely brilliant when he trained Malia showing her how to turn, kiss him, say yes and no, wave and splash, shake her tongue and blow bubbles."

It marked the first ever holiday for the youngster, who has endured years of open heart surgeries.

And while his prognosis is unclear, his family say they are making the most of their time together.

#MarineWildlife - Preliminary results from the post-mortem on the female killer whale that stranded in Waterford last week show no obvious cause of death.

As previously reported on Afloat.ie, the five-metre-long female orca was discovered near Tramore last Friday (30 January) amid an unusually high number of cetacean strandings in the first month of this year.

While it was suggested that the killer whale's worn teeth might point to malnutrition, Dr Simon Berrow of the Irish Whale and Dolphin Group (IWDG) explains that such teeth are typical of 'type 1' orcas in the North Atlantic.

The 'type 1' ecotype feed mostly on fish, and are smaller than their 'type 2' marine mammal-eating counterparts.

According to Dr Berrow, samples of skin have been taken for analysis, and tissue from the blubber, liver, kidney and muscles will be studied in greater detail for potential contaminants that could lead to various conditions such as infertility.

"As biologists we can only explore the life of this whale and not determine the cause of death," he says. 

"Obviously if there was something obvious or a severe infection, etc, we would recognise this but often an animal may have a number of 'conditions' which are not fatal, and determining cause of death is based on the most likely fatal condition.

"Unfortunately Ireland does not have a post-mortem system for marine mammals, unlike most European countries, so the factors leading to mortality of stranded animals is not known," he adds.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) reports on a killer whale stranding near Tramore in Co Waterford yesterday (Friday 30 January).

The five-metre-long female orca was described as being in "a very fresh condition" and was found to have very worn teeth, which points to malnutrition as a potential cause of death.

A post-mortem is scheduled to be carried out tomorrow by a team from the IWDG and Galway-Mayo IT.

The incident is the latest in a "disturbing high" rate of cetacean strandings around the Irish coast this January, with a total of 32 recorded across nine identifiable species.

While it's as yet unknown what has caused this spike in numbers, the recent severe weather systems coming from the Atlantic may be a factor in driving carcasses of animals that may have died of natural causes towards the Irish coast.

#MARINE WILDLIFE - The Irish Whale and Dolphin Group (IWDG) has recorded another first for the North Atlantic, with evidence showing that killer whales are feeding on ocean sunfish.

Mark Holmes of the Natural History Museum confirmed the presence of parasites unique to the sunfish found within the carcass of a female orca stranded in Doohooma in Co Mayo.

"These parasites did not originate from the whale's stomach, but came from the prey which it had eaten," said the IWDG's Conor Ryan.

"This was confirmed when the partially digested bones in the stomachs were eventually identified as those of a sunfish beak."

The discovery may explain a recent study of UK waters which found sunfish taking unusually deep dives, possibly to avoid cetaceans and other large predators.

The Irish Whale and Dolphin Group (IWDG) reports that a killer whale was found stranded in Tullaghan Bay, Co Mayo earlier this month.

A post morten was carried out on the carcass of the female killer whale by Conor Ryan and Alessandro Pierini of the Galway-Mayo Institute of Technology. The good condition of the carcass also allowed the team an opportunity to examine its stomach contents, which did not include any foreign objects.

The killer whale, which was stranded on the beach at Doohoma, was found to be pregnant with a large near-term female calf which was oritented backwards in the birth sac, though there is no obvious connection to the cause of death.

According to the IWDG, it is only the 15th stranding of a killer whale in Ireland since records began, and the seventh in the last 40 years. A pectoral fin was removed for display at the Natural History Museum.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
