Size It Up Animals answer: October 4
The five Animals silhouettes for October 4, 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 31 ran from a black widow spider (3.8 cm) to a sperm whale (16 m). The widest gap was round 1, Common House Gecko against North American Beaver, at 7.5×; the closest call was round 3, Etruscan Shrew against Black Widow Spider, only 1.1× apart — the kind of round that separates a 90 from a 60.
