It’s fascinating how much more you see when paying the close attention needed for drawing.
I once took a group of scientists to the National Marine Aquarium in Plymouth, where they spent an hour or so drawing various creatures. They were amazed by what they noticed, even in fish they had spent years studying but never ‘seen’ so fully before.
I feel that illustration has always been been the most engaging way to explain and understand the natural world. Scientific writing is just as important, but I suspect you are looking at my pictures now more than this text.

In the past, before photographs, illustration was the only way to visually represent the natural world. Some antiquarian prints show some rather strange interpretations of the living world, especially the rare and bizarre, and can lead to us wonder how they misinterpreted creatures we are now familiar with. Dead, often decaying, specimens were often drawn, and not having seen the living specimens, a bit of guesswork was added to complement the exaggerated descriptions of travellers’ tales, hearsay and myth.
Today there is much more visual information to hand, but even so, it is still up to the illustrator to interpret this information. Illustrators need to observe not only the visual shapes that make up the whole, but how they layer up and fit together. A photograph, no matter how good, can’t always show everything in one view, which is what an illustrator aims to do.
Collation of correct descriptions, correct photographic material and in person descriptions, as well as a meticulous observation and understanding, is key to any scientific illustrator’s work.
