Rock Pool Habitat
Dig your own rock pool to give crabs, shrimp, and whatever else the tide brings in a temporary home
A shallow, wide pool dug with a rocky or shell-lined base, designed specifically to hold water and shelter for small sea creatures caught while rock pooling — a gentler, more purposeful cousin of the standard sand pool, built for observing wildlife rather than just for paddling.

When to Dig It
Best Conditions
How to Dig It
- Choose a spot close to where you're collecting from, on flat sand just above the waterline.
- Dig a shallow, wide pool, no more than 20cm deep, with gently sloping sides so small creatures can't easily climb out.
- Line the base with a few flat stones, shells, or a patch of seaweed for shelter and somewhere to hide.
- Fill with seawater carried by bucket, or positioned close enough that the tide tops it up naturally.
- Add creatures gently — small crabs, shrimp, or anything caught while rockpooling — and always return them to the sea before you leave.
Variations
Dig several connected pools of different depths to sort creatures by size, or add a small channel connecting it to the sea so it refreshes naturally as the tide comes in.
Seasonal Tips
Spring
A good season for rockpooling generally, with plenty of small creatures active in shallow water.
Summer
Keep the pool topped up regularly — warm summer sun heats shallow water quickly, which isn't comfortable for anything living in it.
Autumn
Cooler water and calmer conditions often make creatures easier to spot and catch.
Winter
Fewer people digging means fewer disturbed rockpools nearby — good conditions if you're wrapped up warm.
