A dreary, stormy day in Dublin city centre was brightened with the appearance of a common dolphin swimming up the River Liffey as far as the Loopline Bridge.

The Irish Whale and Dolphin Group (IWDG) says it got its first reports early this morning (Wednesday 28 November) from the Jeanie Johnston, whose John O’Neill shot this video of the solo cetacean swimming loops in the river.

However, the IWDG moved to assuage public concerns over this particular animal — saying that if it was swimming as strongly as sightings suggested, it would be more than able to swim back to sea.
It’s suggested that this short-beaked visitor may be one of a pod of some 20 dolphins known to be feeding off the East Coast this month.
More people are reading than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Marine Wildlife Around IrelandOne of the greatest memories of anyday 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 . 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 , 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.

The natural of the River Liffey is an integral part of its story. It encompasses the physical geography, ecology and biodiversity along the river. All of these facets of the Liffey are significant in their own right. They have also played no small part in influencing human activity and built along the river. The natural of the River Liffey changes greatly as it makes its way from the Wicklow Mountains to Dublin Bay.

The Dance Of Life
The source of the river is in an area of blanket bog in the Wicklow Mountains known as the Liffey Head bog. Blanket Bogs cover much of the upland areas of Ireland, include vast stretches of the Wicklow Mountains. Here the covering of peat which has built up over thousands of years is about two metres thick. The main plant species in this area are heathers, mosses and bog cotton and the process of peat formation is still taking place as here as these plants decay. Bog cotton produces white tufts each summer from which it gets its name. The bog is home to the Red Grouse, a rare and endangered species of bird.
The Wicklow Mountains as a whole is home to an estimated 15, 000 wild deer and these shy creatures can sometimes be spotted close to the river. Many of them are hybrids due to the interbreeding of the native Irish red deer with the sika deer that were introduced from Japan in the 19th century.
The waters of the Liffey form an important habitat for a variety of birds and fish. The most prominent fish species are salmon and eels. Each year, salmon enter the Liffey from the sea and swim upstream to spawn in the upper reaches of the river and its tributaries. A special shaft was constructed within the dam at Leixlip that allows the fish to negotiate their way upstream. Once they hatch, the young salmon commence a long journey in the opposite direction to the waters of the Atlantic where they feed before returning again to complete the cycle. However, they have never been able to penetrate above Poulaphuca and are not found in the upper reaches of the river.

Eels undertake the same migratory process in reverse. They breed in the Sargasso Sea at the other side of the Atlantic Ocean and swim across to take up residence in the Liffey. Most stay in the lower reaches around Dublin but some of the more adventurous ones have been known to negotiate the weirs and head upstream.
The River Liffey was the subject of an important study of trout carried out in the 1930s by Dr. Rowland Southern and Dr. Winifred Frost. They showed that trout in the alkaline waters of the Liffey, where the river flows over limestone, grow to a larger size than trout in the more acidic waters of the upland areas. Ballysmuttan in Wicklow and Straffan in Kildare were the two main sites on the Liffey where this study was conducted. Blessington Lake and Leixlip Reservoir are the two most popular angling spots along the Liffey. Trout, pike and perch are amongst the species found here. Unfortunately, trout numbers in Blessington Lake have been adversely affected by the presence of pike and perch.
Blessington Lake’s importance for birds has been recognised by its designation as a Special Protection Area and a Wildfowl Sanctuary. It is home to a number of birds who migrate here from the north during the winter months. Of particular note is the colony of Greylag Geese, a species that has been declining in Ireland in recent decades but is flourishing at Blessington. Other notable bird species are the Crested Grebe and the Lesser Black-backed Gull. More common birds like Mallard, Teal, Mute Swan, Whooper Swan and Cormorant also occupy the lake and feed on the surrounding grassland. Another bird present on the lake but found right along the River Liffey is the Grey Heron, which can be spotted standing silently in the waters waiting for the opportunity to catch fish. Much smaller than the heron is the brilliant blue kingfisher which nests along the riverbanks. It can sometimes be seen close to the bridge in Newbridge.
