Welcome to Cornish Rock Pools

Thinking of going rock pooling in Cornwall? You’ve come to the right place.

Read on to find out where and how to rock pool, what you might find, my latest tips and discoveries and groups to join if you want to learn more.

There’s something about rock pooling. It’s a window on the underwater world. It’s the freedom of wandering between the blue sky and sparkling sea, never knowing what you will find. It’s a joy every child should experience, and that every adult should rediscover.

Found in the rock pools this week…

 

The colder water and gales this time of year mean that most of the animals I’ve seen this week are true stalwarts of the rock pools, experts in surviving in the intertidal zone. With less seaweed in the pools this is a great time of year for spotting all sorts of crabs, hermit crabs, sea snails and stalked jellyfish.

Surprisingly, there are already some babies around. Tiny juvenile sea hares are chomping their way through the seaweed. By the spring, they will have grown into fat adult sea hares with leopard-spot markings, and they’ll converge en masse to lay their pink-spaghetti eggs on the lower shore.

The babies are vivid red with black edges to their parapodial lobes.

I’m delighted that Cornish Rock Pools has twice been named ‘Blogger of the Week’ in 2016 and 2017 by the BBC Wildlife Magazine. My first award was for my report on finding and photographing these gorgeous Scarlet and gold cup corals. Read more here.
