Size It Up Animals answer: August 18

The five Animals silhouettes for August 18, 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.

This pre-launch puzzle ran from a house mouse (8 cm) to a megalodon (16 m). The widest gap was round 3, Plains Zebra against House Mouse, at 29×; the closest call was round 1, Cheetah against Great Hammerhead Shark, only 3.1× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Cheetah vs Great Hammerhead Shark

    Great Hammerhead Shark · reference · 4 m
    Cheetah · true length · 1.3 m

    3.1× shorter than the great hammerhead shark

    A cheetah's body is about 1.3 m long — and it covers that distance in a fiftieth of a second at full sprint.

  2. ROUND 2

    Wandering Albatross vs Golden Retriever

    Golden Retriever · reference · 1 m
    Wandering Albatross · true wingspan · 3.1 m

    3.1× wider than the golden retriever

    The wandering albatross has the widest wingspan of any bird: about 3.1 m.

  3. ROUND 3

    Plains Zebra vs House Mouse (Body)

    House Mouse · reference · 8 cm
    Plains Zebra · true length · 2.3 m

    29× longer than the house mouse

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

  4. ROUND 4

    Emu vs Megalodon

    Megalodon · reference · 16 m
    Emu · true height · 1.7 m

    9.4× shorter than the megalodon

    An emu stands about 1.7 m tall — eye to eye with an adult human.

  5. ROUND 5

    Humpback Whale vs Galápagos Giant Tortoise

    Galápagos Giant Tortoise · reference · 1.3 m
    Humpback Whale · true length · 14 m

    11× longer than the Galápagos giant tortoise

    A humpback whale is about 14 m long — half a blue whale, with flippers a third of its length.
