casquelike
Casquelike is an adjective used to describe something that resembles a casque. A casque is a helmet or a helmet-like appendage, often found on the heads of animals such as birds or insects. Therefore, when something is described as casquelike, it implies it has a similar shape, structure, or appearance to a helmet. This could refer to a rounded, protective covering, a prominent crest, or a structure that stands out from the main body in a way reminiscent of a helmet.
The term is often employed in descriptive biology or zoology to detail the morphology of various creatures.
