#MARINE WILDLIFE - The Irish Times reports that the sperm whale that was stranded in Connemara at the end of last year has been buried at sea.

The 13-metre whale carcass has attracted thousands of onlookers to Omey Island in Co Galway.

As previously reported on Afloat.ie, the sperm whale was found beached with a broken lower jaw and shed of its skin.

The whale carcass was towed out to sea west of High Island on Thursday after being deemed too large to bury on land.

"Chances are it died offshore and got washed in with the wind," said Dr Simon Berrow of the Irish Whale and Dolphin Group (IWDG).

The IWDG added that such strandings were relatively common, although as reported on Afloat.ie last year there has been growing concern over the rising number of dolphin deaths along the south coast in particular.

A sperm whale that beached on a sand spit in Dungarvan, Co Waterford on Friday has died.
The male whale had been spotted off the coast in the 24 hours before it was discovered 'live stranded' on Cunnigar Strand.
Rescuers said there was "no effective way" of refloating the 10+ metre long whale from what became its final resting place.
"Once they come this far inshore they are pretty much doomed," the Irish Whale and Dolphin Group's (IWDG) Pádraig Whooley told the Irish Examiner.
No decision has yet been made regarding disposal of the whale carcass, but Irish Weather online quotes Whooley as saying it is "a wasted opportunity when these magnificent specimens are simply hauled off for incineration".

I am reflecting this week on a varied list of maritime issues which have arisen in my writings on marine topics.

Following recent pieces I wrote about the attitude of political parties in the General Election towards the marine sector, I had a telephone call from a senior Fine Gael politician and, lo and behold, the party included the marine sector in its manifesto, pledging to restore the Department of the Marine, abolished by Fianna Fail. I await post-election developments with interest.

It has been a good week for those interested in protection of whales and dolphins. Hundreds of dolphins were spotted off the Old Head of Kinsale, apparently following shoals of herring and sprat on which they were feeding.

In the Antarctic the Japanese whaling fleet was forced to give in to pressure to stop culling. The Japanese have killed hundreds of whales every year, claiming this was for "scientific purposes," even though it has been identified worldwide as for human consumption. The fleet was ordered home by its Government after increasing international pressure.

The Irish Whale and Dolphin Group published its annual report this week. It was formed in December 1990, dedicated to the "conservation and better understanding" of cetaceans - whales, dolphins and porpoise - in Irish waters through "study, education and interpretation." IWDG turnover in 2010 was around €300,000. It has dealt with up to 10,000 queries a month for information on its website. A total of 92 strandings of 128 individual cetaceans was reported to the IWDG in 2010. This compares to 137 strandings of 169 animals for 2009.

This week oil prices rose because of the unrest in Libya and David Surplus, Chairman of B9 Energy Britain's largest windfarm operator, warned that sooner or later oil will run out. BP is examining the possibility of building a fleet of carbon-neutral, wind-powered sail ships planned, to carry world trade.

On the international sailing scene the new AC 45, forerunner of the next generation of America's Cup boats was launched in New Zealand and had its first capsize. The wing-sailed catamaran is designed for speed and close racing, capable of making up to 30 knots, while intended to be handled in tight, tactical courses. An exciting boat to sail, it will also be very testing of ability. The first capsize of the new boat occurred on Auckland's Hauraki Gulf, hit by what was described as "a freak gust of wind," while the crew were doing maintenance on board before a sailing test.

It capsized fully, ending upside down. Three support vessels were needed to pick up the crew and right the boat which was sailed back to its base in Auckland. There was damage to the wing sail, but no injuries to the crew. However, helmets may be an additional precaution needed for sailing these boats, which are to be used in the AC World Series! This will be a circuit of eight regattas for which venue bids are being made at present, with fleet and match racing, to raise the profile of high-performance sailing on worldwide television. Racing is to start in July, with regattas running until May of next year, leading into preparations for the next full AC series in the bigger AC72 catamarans in 2013 in San Francisco.

As the past week showed, there is always something interesting in the sea.

Rescuers were sadly unable to save an 18ft juvenile minke whale found stranded at Blackwater Pier, near Kenmare, Co Kerry last Friday.
The Irish Independent reports that despite the best efforts of local people and the National Parks and Wildlife Service (NPWS) to refloat the whale, the call was made to put it to sleep.
"It was so long out of the water it was pointless to try to refloat it as its internal organs would have been damaged," said local ranger Michael O'Sullivan.
The tragedy - the latest in an increasing number of strandings in the UK and Ireland - brought out more than 100 local residents to pay their respects at Blackwater Pier, a popular fishing spot.

Plans to carry out a post-mortem examinations on thirty-five Pilot whales found dead on a beach in Co Donegal yesterday have been cancelled due to bad weather according to Dr. Simon Berrow of the Irish Whale and Dolphin Group (IWDG).

Up to thirty-five  Pilot whales were found dead on a beach in Co Donegal. The whales were discovered on Rutland Island near Burton port yesterday afternoon on a beach and have been confirmed as pilot whales, mostly mothers and calves.

A team from the Galway-Mayo Institute of Technology led by Dr Ian O'Connor and the Irish Whale and Dolphin Group are planning to travel to record length, gender and obtain photographs to see if they can be matched to the recently observed Scottish animals. Skin samples and teeth will also be collected for genetics and life-history studies.

According to locals the whales had been seen feeding in the area around Aranmore Island since Tuesday. 

A group of around 30 pilot whales were monitored in South Uist in the outer Hebrides, Scotland last weekend for fear of their live-stranding. The IWDG believe it may be the same group.

Pilot whales have a tendency to strand themselves in large numbers and a similar incident occurred in Co Mayo a few years ago. In June Cape Verde islanders abandoned hope for the survival of 92 pilot whales that were found washed up in a mass beaching. In September in New Zealand at least 25 pilot whales died after beaching themselves in a north Wellington bay as rescuers battled to save almost 50 more stranded.

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.
