PSA: don't touch jellyfish even if washed ashore.

I'm in Llandudno for a holiday. It's lovely. During low tide, the west shore goes out so far it's bonkers – and you can walk around and find cool things. There are loads of jellyfish here.

Absolute unit #1: Lion's mane jellyfish.

These have very painful stings.

This danger pancake was so big that I almost missed it as it sort of blended in to the beach. This is the biggest jellyfish I have ever seen and apparently they get way bigger. The phone and hand really didn't do it justice.

Absolute unit #2: barrel jellyfish

These have mild stings.

Smaller in than the lion's mane I saw, but I had my rucksack for comparison purposes this time.

Here's a compass jellyfish

Some cool little blue jellyfish

Note: jellyfish are already dead by the time you find one. They're 95% water and dehydrate within minutes of washing ashore. They're basically a digestive system with some tentacles. They don't have a brain. But they can still sting.
