crestless

Lacking a ridge

Crestless describes something that lacks a crest—the raised tuft, plume, or ridge typically found on the heads of certain birds, reptiles, or helmets.

In ornithology, it distinguishes species or individuals without the distinctive head feathers that characterize their crested relatives.

The term extends to heraldry, where a crestless coat of arms lacks the ornamental device usually displayed above the shield.
