#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.

Investigators have warned of the dangers of drinking at sea following their investigation into the death of two yachtsmen off Inishboffin in October last year.
Donal McEllin, 63, and Ger Feeney, 56, died while attempting to return to their motor yacht Quo Vadis in the early hours of 10 October.
The inquiry by the Marine Casualty Investigation Board (MCIB) found that the pair had set off for the yacht - which was moored in Inisboffin Harbour - on a motor-driven inflatable tender after several hours socialising in Day's Pub on the island.
The report also found that they had declined an offer to be ferried back to the yacht.
A witness, Ian Day, recounted that he drove his jeep to the end of the pier and used his headlights to assure himself that the tender had reached the vessel. Though it had been agreed with both men that they would turn off the external lights on the vessel when they safely boarded, it was assumed that they had forgotten.
The bodies of both men were discovered the following morning. McEllin’s body was found lying on West Quarter Beach adjacent to where the vessel was moored, while Feeney’s body was found afloat, lying under the upturned tender. McEllin’s lifejacket had inflated but was entangled around his neck, indicating that the groin strap was not properly tied.
Based on the available evidence, the MCIB concluded that the deaths were the result of attemping a night-time transfer from a small inflatable boat to a larger vessel swinging on its mooring, combined with "possible tiredness and diminished human performance resulting from the effects of alcohol".

Naval Visits focuses on forthcoming courtesy visits by foreign navies from our nearest neighbours, to navies from European Union and perhaps even those navies from far-flung distant shores.

In covering these Naval Visits, the range of nationality arising from these vessels can also be broad in terms of the variety of ships docking in our ports.

The list of naval ship types is long and they perform many tasks. These naval ships can include coastal patrol vessels, mine-sweepers, mine-hunters, frigates, destroyers, amphibious dock-landing vessels, helicopter-carriers, submarine support ships and the rarer sighting of submarines.

When Naval Visits are made, it is those that are open to the public to come on board, provide an excellent opportunity to demonstrate up close and personal, what these look like and what they can do and a chance to discuss with the crew.

It can make even more interesting for visitors when a flotilla arrives, particularly comprising an international fleet, adding to the sense of curiosity and adding a greater mix to the type of vessels boarded.

All of this makes Naval Visits a fascinating and intriguing insight into the role of navies from abroad, as they spend time in our ports, mostly for a weekend-long call, having completed exercises at sea.

These naval exercises can involve joint co-operation between other naval fleets off Ireland, in the approaches of the Atlantic, and way offshore of the coasts of western European countries.

In certain circumstances, Naval Visits involve vessels which are making repositioning voyages over long distances between continents, having completed a tour of duty in zones of conflict.

Joint naval fleet exercises bring an increased integration of navies within Europe and beyond. These exercises improve greater co-operation at EU level but also internationally, not just on a political front, but these exercises enable shared training skills in carrying out naval skills and also knowledge.

Naval Visits are also reciprocal, in that the Irish Naval Service, has over the decades, visited major gatherings overseas, while also carrying out specific operations on many fronts.

Ireland can, therefore, be represented through these ships that also act as floating ambassadorial platforms, supporting our national interests.

These interests are not exclusively political in terms of foreign policy, through humanitarian commitments, but are also to assist existing trade and tourism links and also develop further.

Equally important is our relationship with the Irish diaspora, and to share this sense of identity with the rest of the World.
