There are many and varied weird eating habits of humans throughout the world, and, I would classify a person who likes Marlin to have a weird sense of taste as far as fish is concerned. Each to the own I guess.
A little off topic, but, I was searching the web in regards to our noisy little Cicadas that invade our neighborhood during the Christmas season and was amazed to find that they are a popular source of food/protein in many countries of the world. Having said that, If I only had a choice between Marlin and Cicadas, I reckon I'd go with the former.
