My son took this picture underwater of a jellyfish. It is like the common jellyfish but without the four pink rings. Is it unusual?

It’s the crystal jellyfish, Aequorea spp, which is found in Irish waters. It is famous for being a source of a green fluorescent protein useful in molecular biology research. The discovery of the molecule won a Nobel Prize.

I took this photo of a heron on the Lagan. I’ve only ever seen grey herons, but as you can see this one is blue.
