#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 Marine Institute today welcomed the publication of a major international marine environmental status report highlighting evidence of climate change and ocean acidification in the North Atlantic and calling for the creation of more Marine Protected Areas. The Quality Status Report 2010 was compiled by an international team of scientists, including Marine Institute experts, from countries participating in the Oslo-Paris Convention (OSPAR).

Speaking from the launch of the report in Bergen, Norway, Minister of State with responsibility for Sustainable Transport, Horticulture, Planning and Heritage, Mr. Ciaran Cuffe T.D. said that Ireland welcomed this evidence-based assessment of the marine environment as a 'major milestone.'

"Such periodic holistic assessments are essential 'barometers' allowing policy makers to gauge overall progress towards sustainable management and identify those actions essential to deliver clean, diverse, healthy and productive seas around us," said Minister Cuffe. "Such actions are critical to maintaining our seas and oceans as a sustainable resource for this and future generations."

According to the Report, climate change and ocean acidification effects are now evident especially in the northern OSPAR areas. In addition, human uses of the marine environment, such as offshore renewable energy, offshore oil and gas production, mineral extraction and shipping, are increasing and must be managed in a coordinated way, backed up by research on impacts, if environmental damage is to be avoided.

Furthermore, the decline in biodiversity is far from being halted and actions, such as extending the network of offshore Marine Protected Areas (MPAs), are required to improve the protection of threatened and/or declining species and habitats. In December 2009 Ireland designated 19 MPAs including 4 offshore MPAs.

However, the Report states that there has been progress in reducing pollution from nutrients, certain hazardous substances and radioactive substances in our oceans and seas, although continued efforts are needed. In addition, there have been improvements in fisheries management, although fishing activities continue to have large impacts on marine ecosystems in the seas around Ireland.

"The Marine Institute is delighted to have participated closely in the development and production of this assessment by acting as the focal point for Irish involvement in the process and by providing data and scientific input," said Dr. Peter Heffernan, CEO of the Marine Institute. The QSR 2010 Report is a product of cooperation between many experts from 15 OSPAR countries. The Department of Environment, Health and Local Government act as Head of Delegation for Ireland to OSPAR.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
