Yesterday was stormy all day with gale force winds driving the tide up the shore. This mermaid’s purse was still intact. It probably belongs to a nursehound (aka greater spotted dog fish) – which, confusingly, is a type of cat shark (Scyliorhinus stellaris). But this is one egg that won’t make it.
The pale, bobbly egg cases of the common edible whelk (Buccinum undatum) look more like some kind of seaweed than something animal.
Shells were the main thing washed up by the storm:
Along with all the whole, undamaged shells, were lots of chippings of nacre from oyster shells, making the whole bleach glint in the sunshine.
