scale

Also known as scales, Animal Scale, Animal Scales

small rigid plate that grows out of an animal's skin

AI overview

A scale is a small, rigid plate that grows out of an animal's skin, typically found on fish, reptiles, and some other creatures. Scales matter because they protect the animal's body from injury, water loss, and environmental damage while allowing flexibility and movement.

Keeled scales of a colubrid snake (banded water snake; Nerodia fasciata)

In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate made out of keratin that grows out of vertebrate animals' skin to provide protection. In lepidopterans (butterflies and moths), scales are plates on the surface of the insect wing, made out of chitin instead of keratin, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function.
