SCARY FISH
Why are they scary? As a child I always thought it was kind of creepy seeing their innards so clearly through their flesh and scales. Creepy because I knew I was not all that differently formed: I had a stomach, liver, intestines, spinal column etc. The tiny fish's transparency was such a reminder of the fragility of the flesh. Maybe scary is not the right word, but deeply unsettling, more than any cartoon ghost could possibly be!
