Where the name comes from

Trioceros is “three-horned”, from treîs and kéras: the male carries one horn on the snout and two above the eyes, and the result resembles a miniature triceratops closely enough that the English name says so outright. Jacksonii recalls Frederick Jackson, ornithologist and British governor of East Africa. Chameleon comes from the Greek chamailéōn, “ground lion”.

Characteristics

  • 01

    It gives birth to live young, as many as thirty at a time.

  • 02

    The two eyes move independently and cover three hundred and sixty degrees.

  • 03

    Its toes are fused into two opposing bundles, like pincers.

What sets it apart

The horns are not for defence against predators but for pushing: two males square up side by side on a branch, lock horns and try to lever each other off, exactly as stags do. This species reached Hawaii in 1972 with a handful of animals imported for a pet shop and released into a garden because they looked sickly; the islands now hold thriving populations, and the chameleons eat endemic snails that exist nowhere else on Earth.
