Description: Grey seals occurred off all Irish coasts and foraged offshore in Irish Shelf waters.They were recorded at low relative abundances throughout the Irish Sea and over Irish shelf waters, with animals predominantly occurring in inshore waters but also occurring as far west as the shelf edge. Occasionally grey seals can venture far offshore to the shallower waters of the Porcupine and Rockall Banks and to deep waters beyond the shelf slopes. Data from satellite tagged animals indicate that animals move between Ireland and the UK (Matthiopoulos et al. 2004) and further afield to the Faroe Islands. The population estimate for grey seals in Ireland in 2005 was between 5500—7000 animals (Ó Cadhla et
al. 2005).

Description: The harbour porpoise was a common inshore species found around the entire Irish coast and was observed from many headlands throughout the year (Berrow et al. 2010). In offshore areas, harbour porpoises occurred at highest densities in the Irish Sea and its northern and southern channels.The highest relative abundances were recorded in the western half of the central Irish Sea (figure 3).The 2005 SCANS II survey estimated a population of c.15,000 harbour porpoises in the Irish Sea, with a total estimate of 385,000 in Northwest
European waters (Hammond et al. 2006). Harbour porpoises were less commonly encountered in offshore shelf waters of the Atlantic and Celtic Sea. This may partly be due to differing survey methods between the Irish Sea (where ferries were extensively used) and elsewhere (where research and naval vessels
were used exclusively). It may also partly relsult from less favourable survey conditions in Atlantic waters as the detection rates for harbour porpoise decrease significantly in sea states greater than Beaufort 2 (Reid et al. 2003).

Description: Sightings of Atlantic white-sided dolphins occurred primarily in deep waters (>200 m) on or adjacent to the slopes of the Irish continental shelf and offshore banks. Sightings also occurred in the deep waters of the central Rockall Trough.
Occasional sightings of white-sided dolphins were made over Irish shelf waters, however such sightings were rare and it is clear that this species shows a strong preference for waters deeper than 200 m Highest relative abundances were ecorded in the Rockall Trough to the northwest of Ireland, where group sizes of up to 250 animals were recorded. O’Cadhla et al. (2004) estimated some 5,500 whitesided dolphins for the Rockall Trough and Porcupine Bank in August 2000.

Description: Common bottlenose dolphins occurred off all Irish coasts with inshore animals moving around the entire Irish coastline (O’Brien et al. 2009) and between the
UK and Ireland (Robinson et al. 2012). Resident or semi-resident groups were present in the Shannon Estuary (Berrow et al. 1996) and Cork Harbour (Ryan et
al. 2010b). There is increasing evidence (from sightings and genetic analysis) to suggest that an offshore ecotype of bottlenose dolphin exists in Irish waters (Wall et al. 2009, Oudejans et al. 2010 and Mirimin et al. 2011). Though bottlenose dolphin distribution was continuous from inshore to offshore areas, some evidence existed that offshore animals exhibited preference for the slopes of the Irish Shelf and offshore banks. Bottlenose dolphins also occurred in abyssal waters, where they sometimes formed mixed species groups with pilot whales.

Description: <metadata></metadata>
Risso’s dolphins are very robust with an average adult body length of 3.2 m.At birth calves are grey (overall colour ranging from light to dark grey) with a paler
underside.As they age, adult Risso’s become paler due to increasing levels of white scarring resulting from tooth rake marks gained during social interactions.
Adult Risso’s appear pale grey or largely white (depending on levels of scarring), particularly around the head.There is a white anchor-shaped patch on the chest and the underside of the belly is also typically white.The head is blunt and bulbous, with no evident beak.A distinct vertical cleft is evident on the front of the melon. A tall, dark and very prominent dorsal fin is located mid-way along the back.The tip may be rounded or pointed with a concave trailing edge.The pectoral fins are long, dark and sickle shaped.A small but noticeable blow may be seen at close range. Risso’s dolphins can be very acrobatic at the surface with
repetitive breaching and tail slapping.

Sightings of white-beaked dolphins were rare in Irish waters. Occasional sightings were recorded from inshore waters of the northwest coast. The 2005 SCANS II survey produced an estimate of between 250 and 1350 animals for Irish Shelf waters (Hammond et al. 2010). However such estimates were inconsistent with the extremely low sightings rates for white-beaked dolphins in Irish waters. White-beaked dolphins were sighted year round in Irish waters. However the scarcity of sightings meant that it was not possible to robustly assess temporal changes in distribution and abundance.

Description: The majority of beaked whale sightings in Irish waters were recorded in slope and canyon habitats of the Rockall Trough, but also in the deeper waters of the
central Rockall Trough (figure 24). Sightings also occurred in the Porcupine Seabight and occasionally in inshore coastal waters, though the latter were
predominantly associated with subsequent stranding events (IWDG 2013).
Strandings data indicated a wider distribution for beaked whales in deep waters off the entire western shelf edge. One area of high beaked whale activity has been identified in Irish waters, on the southern slopes of the Rockall Trough. This is an area containing a number of large subsea canyon systems. Such canyons have been identified as important habitat for beaked whales elsewhere (Waring et al. 2001).

Description: Sightings of fin whales were recorded off all coasts, with highest relative abundances occurring off the south coast in waters extending from inshore,south to the Labadie Bank and east to the Celtic Deep. This area was a foraging ground for fin whales feeding on pelagic schooling fish. Photo identification studies in inshore waters along the south coast showed that some fin whales exhibited a degree of site fidelity, with the same individuals being recorded across several years (Whooley et al. 2011).

The range of observed Humpback Whales made by scientific observers on board ships of opportunity between 2005 and 2011 and recorded in Atlas of the Distribution and Relative Abundance of Marine Mammals in Irish Offshore Waters: 2005 - 2011.
Description: Killer whales were recorded predominantly in inshore waters of the northeast, north, west and south coasts. A small number of sightings also occurred in offshore waters over the Irish Shelf (figure 22). No sightings were recorded from the Irish Sea, however anecdotal evidence from divers and yacht crews indicate killer whales pass through the Irish Sea but do so well offshore, perhaps due to a lack of major food sources inshore. No population estimates exist for this species in Irish or EU waters. Seven killer whales have been photo identified from Irish waters (IWDG 2013) and all but one of these are known to be part of the ‘West
Coast Community’ killer whale group, first identified in waters off the Scottish West coast and consists of just ten animals.This group are known to predate on both marine mammals and fish (HWDT 2013).

Description: Long-finned pilot whales primarily occurred in deep waters (500 m+) beyond the Irish Shelf edge (figure 19). Highest relative abundances were recorded in the
Rockall Trough, particularly along the lower continental shelf slopes and the lower slopes of the Porcupine Bank. High relative abundances were also recorded in the vicinity of deep water bathymetric features such as sea mounts. Pilot whales were recorded in the Porcupine Seabight, but at lower densities than in the Rockall Trough. Higher relative abundances were recorded in the deeper waters of the Irish Shelf slopes to the south of the Goban Spur.

Description: Sperm whale sightings occurred almost exclusively in the Rockall Trough.All sightings of sperm whales were recorded in deep waters (>500 m) beyond the edge of the Irish shelf, with the majority of sightings occurring in waters deeper than 1000 m. Sperm whale distribution was focused in areas adjacent to the slopes of the Rockall Trough and over underwater features such as seamounts. The CODA survey of European offshore waters produced an estimate of c1100 animals for waters to the west of Ireland and Scotland (Hammond et al. 2010).They are the most commonly stranded large whale species in Irish waters (IWDG 2013).
