Rare encounter with elusive ocean giant off Mayo coast

Passengers on a boat trip off Acaill, Co Mayo, recently enjoyed a rare encounter with an ocean sunfish.

The sunfish - the largest boney fish in the world - was swimming at the surface when it approached the Achill Sea Safari RIB on an excursion earlier this month.

They are typically found in tropical and temperate waters but they are occasionally seen from boats in Irish waters during the summer.
