How this figure was taken
Animal sizes vary from one individual to the next, so each figure says which individual or average it describes. Heights are taken at the shoulder or standing; lengths run nose to tail tip unless stated.
How the sizes are taken. Each figure says what it measures — height, length, diameter or elevation — and for which individual or convention. Everything is drawn standing upright on one baseline so a single scale holds, including things that are long rather than tall. Values come from the linked Wikipedia article for each item.
