Identifying Your Eggcase

Congratulations on your exciting find(s)! 

We expect you’re eager to find out which species this belongs to! So let’s get started.

PREPARE YOUR EGGCASE

Once at home, we recommend preparing your eggcase(s) by doing a bit of bucket science. Rehydrating eggcases makes them much easier to identify. You’ll also see how much they expand to their true size, and how tough they are to protect the developing embryo!

  • Fill a container with fresh water - you can use anything from a freezer bag to a bucket.

  • Put the eggcase in the water – if possible try to remove all the air so it sinks.

  • Leave to soak for 1-2 hours - the longer it’s been out of water, the longer it’ll need to fully rehydrate. Larger eggcases will need to soak for around 24 hours before they return to their original shape.

  • Remove the eggcase from the water

  • Get cracking with identifying your find!

Once you've identified and photographed your eggcase you can dry them out in a well-ventilated spot. As long as they're empty, they shouldn’t smell.
