A little perspective
Leafy seadragon vs Cassava root: length comparison
The total length of a leafy seadragon is approximately equal to the whole-root length of a cassava root.
The leafy seadragon is a marine fish from southern Australia with leaf-like appendages that help it blend into seaweed.
Cassava root is the starchy, edible tuber of the tropical plant Manihot esculenta, commonly used as a staple food.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
