Size It Up Animals answer: September 11

The five Animals silhouettes for September 11, 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 8 ran from a honeybee (1.3 cm) to a giant manta ray (7 m). The widest gap was round 3, Honeybee against House Mouse, at 6.2×; the closest call was round 2, Chimpanzee against Red Kangaroo, only 1.1× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    House Sparrow vs European Rabbit

    European Rabbit · reference · 40 cm
    House Sparrow · true length · 16 cm

    2.5× shorter than the European rabbit

    A house sparrow is about 16 cm long — the length of a pencil.

  2. ROUND 2

    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.

  3. ROUND 3

    Honeybee (Worker) vs House Mouse (Body)

    House Mouse · reference · 8 cm
    Honeybee · true length · 1.3 cm

    Giant Manta Ray · true wingspan · 7 m

    1.6× wider than the great white shark

    A giant manta ray spans about 7 m wingtip to wingtip.

  5. ROUND 5

    Hippopotamus vs Horse (Thoroughbred)

    Horse · reference · 2.4 m

    1.5× longer than the horse

    A hippo is about 3.5 m long and weighs as much as a small car.
