I think the dogfish eggs or sometimes called Mermaid's purses are white in colour and are peapod shaped (I know I haven't described this verywell) and are attached to kelp.

Found a better explaination for Dogfish eggs - Mermaids' purses are the egg cases of dogfish and rays, both relatives of the shark. The egg cases have long curling strings at the corners that are used to fix them to rocks.
Out at sea the egg hatches and a very young dogfish or ray can be seen developing inside. When the fish is old enough it will break out of the egg case and swim free. This is why mermaids' purses always have holes in the side. Mermaids' purses are the egg cases of dogfish and rays, both relatives of the shark. The egg cases have long curling strings at the corners that are used to fix them to rocks.
