Shell Life of the Seashore

Description

I lawer, uchafbwynt gwyliau ar lan y môr yw archwilio pyllau dŵr a chasglu toreth o gregyn lliwgar a adawyd ar y traeth ar adeg trai. Dyma ganllaw swynol i hanes cregyn môr o bob math ac i’r creaduriaid oedd yn arfer byw ynddynt ar un adeg.
For many, the highlights of seaside holidays are rockpooling and gathering the glorious array of shells left strewn on the beach after the receding tide. Attracted by the infinite variety of shapes and colours, visitors can never resist making a souvenir collection of their own – but little do they suspect the fascinating lives of the animals who once occupied them.
