These rock pools, or tidal pools, are miniature habitats, home to a huge range of animals and plants.

Dungeness crab, in my opinion, is even better than king crab. It’s sweet, easy to eat, not usually cooked in brine, and, what puts it over the top for me, you get to drink the crab butter after cooking. King crab is almost always processed close to where it’s caught and then sold only as legs / claws.
