The carcass of a juvenile humpback whale washed ashore in West Cork is only the ninth such stranding of the species in Ireland, according to the Irish Whale and Dolphin Group (IWDG).

Sightings officer Pádraig Whooley confirmed from images of the marine wildlife specimen captured in Roaringwater Bay yesterday (Wednesday 24 February) that it was a juvenile male not previously recorded in Irish waters.

Such young whales are not unexpected close to our shores at this time of year, when adults of breeding age are either en route to or already at lower-latitude breeding sites such as Cabo Verde off West Africa.

“This is something that some young humpbacks can opt out of, as it’s a long track south to places like the Cabo Verde and with no hope of successfully breeding there is nothing much in it for them,” Whooley explains.

“So a cohort of young, independent humpbacks seem content to over winter at higher latitudes, where there is, or should be, plenty of food for them.”

In this case, however, Whooley says: “The images we’ve received so far suggest it is in rather thin condition and so it may not have fed for some time.

“There are no obvious signs of rope marks or net damage that may suggest entanglement in fishing gear, something that slow-swimming humpbacks that remain inshore are prone to. And there are no large traumas to suggest ship-strike. So as is so often the case, the circumstances underpinning this stranding are unclear.

“IWDG hope in the coming days to visit the site to take detailed measurements and get skin and blubber samples which can be used for genetics, contaminants and stable isotope analyses.”

Whooley adds that the IWDG is in liaison with the National Parks and Wildlife Service (NPWS) regarding examination of the carcass and its disposal, but suggests that because of its remote location “there is no strong case for removal”.

The Irish Whale and Dolphin Group (IWDG) has announced a new educational resource for young and aspiring marine science experts.

Ireland’s Blubber Book: Flukes Junior Vol 1 is a comprehensive workbook on cetaceans – the marine wildlife family comprising whales, dolphins and porpoise – found in Irish waters for primary school children aged between 9-12.

The new resource was created to support support the aims of the National Strategy on Education for Sustainable Development by IWDG education and outreach officer Sibéal Regan and illustrated by the talented John Joyce and Jim Wilson.⁠

“We believe that the first step in becoming an ocean literate and informed society, starts with our youngest citizens,” the IWDG says in its introduction to the resource.

It adds that the workbook “will motivate and empower them throughout their lives to become informed active citizens, who take action for a more sustainable blue future”.

Teachers can use Ireland’s Blubber Book in a classroom setting, by going through the content and worksheets themselves.

But the IWDG is also offering to facilitate virtual workshops “making the experience even more interactive and engaging”.

Interested schools can contact Sibéal Regan at [email protected] to enquire about using this new book in their classroom.

It will also be available from the IWDG shop and will have its official launch online on the IWDG Facebook page next Thursday 28 January at 11am.

The Irish Whale and Dolphin Group’s annual conference is moving online — and broadcasting live from West Clare next Saturday 12 December.

Whale Tales is the annual meeting of the IWDG, where members and people interested in whales, dolphins and porpoises in Ireland are invited to join in a shared appreciation and admiration of these charismatic examples of marine wildlife.

This year, due to coronavirus restrictions. Whale Tales 2020 will be a virtual meeting, with a panel of local speakers calling in from the IWDG head office in Kilrush as well as special guests from further afield.

Among them will be Joy Reidenberg, from the hit TV programme Inside Nature’s Giants, who will discuss the topic of large whale necropsies and what we can learn from them.

In the afternoon, Mags Daly of the Shannon Dolphin Project will tell tales of her favourite mammals and share some of her stories from the Shannon Estuary this summer.

Registration is free for all who want to join in, but donations are welcome to support the IWDG in its recording and conservation efforts.

The full programme of events, including details of how to book your virtual spot, can be found on the IWDG website HERE.

The first Irish and Scottish Humpback 'match' has been made from images taken on the Shetland Islands at the weekend and then matched to photographs of the same whale off Ireland in 2015 and seen again off Irish coastal waters as recently as June 2020.

In an exciting development for Irish marine wildlife fans, the Irish Whale and Dolphin Group (IWDG) confirmed on social media this morning (see below) that the Irish Humpback whale named #HBIRL38 was photographed on 7 November off Whalsay, Shetland. This whale has been recorded 16 times by the IWDG over four years since July 2015 and was last seen off West Cork on 2 June 2020.

“It’s better this way, rather than Fungie wash up dead on the shores of Dingle Bay, [that he] just disappear.”

That’s the message from the Irish Whale and Dolphin Group’s (IWDG) chief executive as nearly two weeks have passed since Dingle’s longtime resident dolphin was last seen in the Co Kerry village.

Writing on the IWDG website, Dr Simon Berrow reminisces about his own encounters with the friendly bottlenose since his own arrival in the West of Ireland in 1988.

And he believes that Fungie has been an inspiration some of the millions who have witnessed him over the years to pursue further interests in marine matters.

But Dr Berrow is also brutally honest about the region’s over-reliance on the marine wildlife singleton as a draw for visitors.

“Building an international tourism product on a single dolphin was never going to last,” he says. “It was unsustainable.”

The Irish Whale and Dolphin Group (IWDG) says it has recently documented evidence of a humpback whale scarred by entanglement in fishing gear in Irish waters.

Humpback IRL#HB43 was photographed in Dingle Bay on Sunday 11 October by IWDG member Nick Massett, who noted in his images some significant scarring on its tail fluke that was not present when the same whale was spotted off West Kerry two months prior.

The charity says this scarring is consistent with entanglement — and it’s believed, based on the marine wildlife giant’s known movements between August and this month, that the lesions were sustained off West Kerry.

Humpback whales regularly feed in Ireland’s inshore waters during the summer and autumn. But this activity also brings the whales into close proximity with active fisheries.

“It’s likely this animal got caught in the rising rope of a marker buoy to a string of lobster pots, or gill net,” Massett says.

Entanglement in fishing gear is an issue of emerging concern to the IWDG, which is working with Dr Charla Basran at the University of Iceland’s Husavik Research Centre to quantify the rate of entanglement of humpback whales in Irish waters.

Dr Basran recently published work showing that 24.8% of 379 individual humpback whales photographed in Iceland presented wrapping injuries and notches known to be indicative of entanglement.

Ireland shares a whale population with Iceland, and the IWDG says will be interesting to quantify the rate of these lesions on whales photographed in Ireland — and potentially reveal where along their journey to the North Atlantic from their southern breeding grounds they pick up their wounds.

The IWDG is planning a workshop on the issue supported by knife-maker Spyderco, which has provided knives customised for cutting ropes from live whales.

The Irish Whale and Dolphin Group has conformed the first validated sighting of a fin whale off Co Donegal.

Liz Morrow captured images of the solo large whale in Donegal Bay off Slieve League earlier this month, estimating it to be around 18 metres in length.

Fin whales are a common occurrence in Ireland’s South West and the Celtic Sea, but have never before been spotted in the inshore waters of the colder North West.

However, with the later sighting of a humpback whale breaching off Malin Beg, it could be a sign that larger marine wildlife are exploring new territory north of Sligo.

“Any large whales that simply look too large to be a minke or humpback and produce a powerful columnar ‘blow’ on surfacing, should be considered as likely candidates,” the IWDG suggests.

“They will often be accompanied by common dolphins who hunt the same sprat and herring shoals and they never lift their tails before diving.”

Suspected fin whales are best approached from the right side and photographed at the head and rostrum “which should reveal the diagnostic lower white right jaw”.

It has emerged that the deadly mass stranding of bottlenose whales in Donegal was preceded by two live strandings in the Faroe Islands two days prior.

And it’s led experts at the Irish Whale and Dolphin Group (IWDG) to suggest the marine wildlife incidents might be linked and “part of a much wider event”.

The group adds that images of two Northern bottlenose whales — of the same species that died in Donegal — were captured the next day in Scotland as far inshore as Greenock Harbour, on the Clyde west of Glasgow.

More recently, two of the deep water cetaceans have been seen in the North Sea off Norfolk, and two others were spotted at the Netherlands’ Eastern Scheldt.

“Clearly something is happening to this group of whales we know so little about,” the IWDG says, adding that the situation also “demonstrates the need for a response protocol” for similar strandings in Ireland.

One of the victims of a deadly mass stranding of bottlenose whales in Donegal last week has not reappeared, according to Highland Radio.

Seven of the marine mammals died in the biggest mass stranding of its kind on record in Ireland, as previously reported on Afloat.ie.

The eighth whale was refloated in the shallows when the tide came in, and hopes were that it would make to back to deeper waters on its own. However it was confirmed to have died the following morning, Thursdasy 20 August.

Local volunteers with the Irish Whale and Dolphin Group (IWDG) have appealed for the public to report any possible sightings, as they are keen to get samples which might reveal more details about the whale pod and its sudden demise.

Elsewhere, rare video has been captured of the humpback whale known as ‘Boomerang’ off West Cork, as RTÉ News reports.

The whale is the third humpback in the IWDG’s records. It was first identified in 2001 thanks to its unique dorsal fin, and has returned to feed in Irish waters regularly over the last two decades.

This story was updated on Monday 31 August to correct details about the refloated bottlenose whale, which was not presumed to have survived as the previous version stated.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
