A dolphin was spotted on a "rare" swim up the River Liffey over the weekend.
A video taken by Eugene Smith captured the common dolphin making it's way up the city's most famous river on Saturday morning.
It is only the second time that the Irish Whale and Dolphin Group has confirmed a sighting of this species in the Liffey system with the only previous one being in November 2018.

The group tweeted: "Video taken by Eugene Smith in Poolbeg, Dublin's River Liffey, shows a common dolphin.
"It is only the second time that IWDG has confirmed a sighting of this species in the Liffey system, making this a rare encounter. Details are available on the IWDG website under sightings."
Dolphins aren’t native to this location, making 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.
The Irish Whale and Dolphin Group are calling for the public and anyone working in the Dublin Port area to keep them posted on any other sightings.
You can report sightings directly to IWDG through their Reporting App with images or videos, or fill out the sightings form on their website here.
