Size It Up Animals answer: September 23
The five Animals silhouettes for September 23, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.
Day 20 ran from a peacock spider (5 mm) to a brachiosaurus (22 m). The widest gap was round 3, Black Widow Spider against Peacock Spider, at 7.6×; the closest call was round 5, Galápagos Giant Tortoise against Plains Zebra, only 1.8× apart — the kind of round that separates a 90 from a 60.
