Trigger Fish

I wasn't even diving! Just going for a brief snorkle and this character came up and stared into my mask. How cute I thought and watched for a minute or so as it swum round and kept coming back to stare at me. He drifted off up to the surface after something to eat and then came back and bit a (small) chunk out of my forehead!
It didn't hurt - much - but I did feel hoodwinked and betrayed. That's the last time I'll trust one of these!
