Melanie Said
When I've made sure that nothing like it exists in any other collection anywhere in the world, I start to write a description of my fish. I study its anatomy. I make lots of measurements. I count its vertebrae, its fins, its teeth. I examine its gill structure. The things I pay most attention to depend on the kind of fish. I look for different features in salmon, than, say, catfish. I record everything I see.
