IPA: /kaɪˈrɒptərən/
KK: /kaɪˈrɒptərən/
A type of mammal that includes bats, characterized by having wings formed from their forelimbs.
The chiropteran flew silently through the night sky, searching for insects to eat.
Chiropteran is formed from "chiro-" (from Greek "cheir", meaning hand) and "pteron" (from Greek, meaning wing). The word refers to creatures that have wings and are capable of flight, specifically bats, which are the only mammals that can fly using their hands as wings.
Think of 'hands' ('chiro-') that are also 'wings' ('pteron') — this helps you remember that chiropterans are creatures like bats that fly using their hands as wings.
