There were some unexpected visitors to a North Dublin this morning much to the delight of locals.
A number of dolphins made a rare visit to Portmarnock beach and enjoyed a frolic in the clear blue waters.
Moira Cassidy managed to capture this amazing footage of the six foot marine mammals floundering in the Irish Sea.
In the video, the group of playful dolphins can be seen larking around in the water at the pristine Blue Flag Beach.
Dolphins aren’t native to this location, meaning this visit is a surprise for many locals in the area.
And here’s some things you may not know about the fantastic creatures:
The killer whale is the largest species of dolphin.
Some can reach speeds of 48 kph.
They don’t chew their food, they swallow it whole!
Bottlenose dolphins can recognise themselves in a mirror.
However, videographer Moira who swims daily on the beach is amongst a growing band of locals who fear that there won’t be any such wildlife like the dolphins if An Bord Pleanala’s plans get the go ahead.
Irish Water are looking to build a sewage treatment plant that is five times the size of Croke Park in Clonshaugh, between Dublin Airport and Portmarnock.
It will pump 200 million litres of secondary treated sewage a minute into the sea just off Portmarnock beach, leaving it seriously under threat.
Portmarnock is the only blue and green flag beach on the entire east coast, and it’s only one of five beaches that has both flags in the entire country which will be impacted if the “monster sewage” plan goes into effect.
This could impact the rapid growth in dolphin watching in Ireland which has increased during the past decade.
The most frequently sighted species is the Short-beaked Common Dolphin and the Bottlenose Dolphin according to Whale Watch West Cork.
Risso’s Dolphins, Killer Whales (Orca) and Long-finned Pilot Whales can also be spotted off Irish coasts.
More rarely there are sightings of other oceanic dolphins such as the Atlantic White-sided Dolphin and the White-beaked Dolphin but they more usually favour the deeper waters of the Eastern Atlantic at the edge of the continental shelf.
