It has just been discovered that some fish use a kind of sign language to help others hunt. So, I decided to investigate the footage I have been capturing over the last couple of weeks for the Tenkara videos to see if trout displayed any tendencies to use sign language – after all, one of the fish they discovered uses sign language is the coral trout. I’ll keep my eyes open in the future to see how they tell each other, “Hey, look at that tenkara fly; it looks yummy!”
