Day 2 ran from a rock pigeon (33 cm) to a blue whale (27 m). The widest gap was round 5, Chimpanzee against Blue Whale, at 18×; the closest call was round 2, American Bison against Horse, only 1.3× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Gorilla (Silverback) vs African Elephant (Bull)

    African Elephant · reference · 3.2 m
    Gorilla · true height · 1.7 m

    American Bison (Bull) vs Horse (Thoroughbred)

    Horse · reference · 2.4 m

    Sea Otter · true length · 1.3 m
