Marine life enthusiasts are being encouraged to head to Clare's coast to see a unique spectacle this week. There have been a number of sightings of basking sharks breaching, or breaking the surface of the water, off Loop Head in recent days. Basking sharks, which are the second-largest sharks or fish in the world, populate much of Ireland's waters during the spring and summer but usually only breach during particularly warm spells. Chief Executive Officer of the Kilrush-based Irish Whale and Dolphin Group, Simon Berrow says it's a great opportunity to see these remarkable creatures.
