Brittle Star Anatomy Diagram - Scientific Illustration & Structural Details #91992 (License: Personal Use)

This high-detail black-and-white engraving depicts a brittle star (class Ophiuroidea), emphasizing its slender, highly flexible arms composed of articulated ossicles and a distinct central disc. The inset magnifies the disc’s internal structure, revealing the madreporite, oral surface, and ambulacral groove system. The fine cross-hatching and stippling techniques convey texture and depth, typical of pre-photographic zoological illustration.

Used in educational resources, museum exhibits, marine biology textbooks, and historical science archives to illustrate echinoderm morphology; serves users seeking anatomical clarity or historical scientific art.
