Is it a dolphin, or somefin else?

This aerial shot of Pwllheli harbour in North-West Wales looks a lot like the aquatic mammal, but the photographer, Rhys Jones, said he'd never realised just how much before.

"I've been up several times above the marina but it's the first time I've noticed this," he said.

"It was an amazing discovery. Once you've seen it, you can't unsee it."

The harbour is actually home to a pod of 300 bottlenose dolphins - well, now 301!

It's not uncommon to see faces in everyday objects, such as the burnt bits of toast, or in the world around us.

The phenomenon is known as face pareidolia (you say it 'pa-ray-doy-lee-ah'), which is when the brain tries to make sense of things and makes you see images that are not actually there.

It happens because the brain recognises something as a possible face in a few milliseconds, but even when it realises the object isn't actually face it still continues to analyse it.

Humans have learnt to identify faces so that they can decide if someone is a friend or a foe - we do this by checking their emotions, so if they are they happy, sad, or angry.

It's for survival - so we can protect ourselves and stay safe - and would've been useful when we were early humans.

That is why people find themselves thinking a plug socket looks a bit sad, or a tree's bark looks a little shocked.
