A couple of days before New Year we headed for Ross Beach on the North West Mayo coast. This is one of our favourite beaches, particularly during the summer. But this was a frosty morning and there was actually frost on the sand, not something I’d seen before.

The tide was going out and had left some interesting things behind it. There was no sign of injury to this flatfish so I am not sure what resulted in its demise. Irish waters have 22 species of flatfish though there are 600 species worldwide.
Flatfish
These sea potato remains (known as a ‘test’), are a common find on this beach but there were probably about twenty. Recent storms may have been a cause. Alive, these little creatures are usually buried up to 15cm deep in sand or muddy sediments. They are also covered with yellow/brown spines. Sea potatoes are related to sea urchins.

There was also a lot of kelp washed up, which again is something that is found after the sea bottom has been disturbed by big waves. Despite the blue sky, the wind was cold so we were all glad to get back to the car.

I’ve certainly never seen frost on a sandy beach before, nor have I heard of sea potatoes but can see the immediate link to sea urchins. A layman’s questions: did the sea potatoes die because they dried out and is there anything actually inside the shell? All fascinating.

No, they probably died of natural causes (or as result of a recent storm) and then got washing up by the tide. By the time the tide has brought them ashore they are empty – the flesh inside probably eaten by small fish or other sea creatures. The tests that get washed up are brittle and easily broken.

They were perfect-TONS of them scattered across the beach. I felt like a kid in a candy store-LOL.

So glad to have found your blog! We used to call Sea Potatoes ‘Holy Mary shells’ when we were children. We rarely came across them but when we did, it really was an exciting find.

What a great name! I love these old local names. My mother calls cuckcoo flowers Hail Mary’s which I think is just a local name to us.
