Sitting in a fantastic restaurant on Rambuttri Road in Bangkok I noticed dozens of these colourful, round lights. Whilst waiting for my BBQ’d Snapper fish and baked potato (which was delicious) I took a quick photograph. It wasn’t until recently, looking through my old photographs that I noticed these are Puffer fish. Called Pakpao in Thailand they are extremely toxic. In fact they’re generally believed to be the second-most poisonous vertebrates in the world.
