Cardigan Bay/ Bae Ceredigion

Site overview: This area stretches from Ceibwr Bay in Pembrokeshire to Aberarth in Ceredigion and goes out to almost 20km from the coast, covering about 1000km2 of sea. Bottlenose dolphins and grey seals call this area home, as well as river and sea Lampreys which are an ancient type of fish with a suckered mouth. You can even catch a glimpse of bottlenose dolphin calves here, as they breed in these waters.
