Size It Up Animals answer: September 16

The five Animals silhouettes for September 16, 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 13 ran from a house sparrow (16 cm) to a giant manta ray (7 m). The widest gap was round 3, Great Horned Owl against House Sparrow, at 3.4×; the closest call was round 1, Chimpanzee against Red Kangaroo, only 1.1× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Chimpanzee (arm span) vs Red Kangaroo (Male)

    Red Kangaroo · reference · 1.6 m
    Chimpanzee · true length · 1.5 m

    1.1× shorter than the red kangaroo

    A chimpanzee's outstretched arms span about 1.5 m — wider than it is tall.

  2. ROUND 2

    Plains Zebra vs Bottlenose Dolphin

    Bottlenose Dolphin · reference · 2.8 m
    Plains Zebra · true length · 2.3 m

    1.2× shorter than the bottlenose dolphin

    A plains zebra is about 2.3 m from nose to rump — horse-sized, and no two stripe patterns match.

    Great Horned Owl (Perched) vs House Sparrow

    House Sparrow · reference · 16 cm
    Great Horned Owl · true height · 55 cm

  4. ROUND 4

    Giant Manta Ray vs Horse (Thoroughbred)

    Horse · reference · 2.4 m
    Giant Manta Ray · true wingspan · 7 m
