Barnacles.jpg

Barnacles are a common site around Ireland’s rocky shores. These tiny animals form the familiar off-white patchwork that often covers large swathes of rock between the high and low water marks. Barnacles are crustaceans, relatives of crabs, shrimps and lobsters, although they were not firmly accepted as part of that group until as late as [...]

The Atlantic mackerel is a common and widespread fish around Irish coasts.

Sharks don’t spring immediately to mind when you think about Ireland’s wildlife.
