Feather Star (Crinoid) Anatomy Diagram - Marine Biology Illustration #1653428 (License: Personal Use)

This precise black-and-white illustration depicts a crinoid-commonly called a feather star-with its characteristic feathery, pinnulate arms extending from a central calyx, supported by a flexible, segmented stalk ending in grasping cirri. The drawing emphasizes morphological features used in taxonomic identification, including arm branching patterns and ossicle arrangement. It serves as an educational tool for understanding echinoderm anatomy and paleontological fossil interpretation.

Used in marine biology textbooks, university lecture slides, museum exhibits, and online encyclopedias to illustrate crinoid morphology; targets students, educators, and researchers seeking accurate anatomical references.
