Unsure

There were lots of these on the beach this afternoon. They're only about 2cm wide but they're a brilliant blue colour. We're not really sure what they are but are guessing they're some type of jellyfish.
Unfortunately the beach was littered with plastic. I filled a bag with rubbish, mainly plastic bottle tops.
My daughter made a friend today and played for 6 hours on the beach. Who needs plastic toys when you can have the outdoors and be happy.
