Tube-Dwelling Polychaete Worm Anatomy - Scientific Illustration #3601929 (License: Personal Use)

This precise black-and-white illustration depicts a sedentary polychaete worm-likely a sabellid or serpulid-partially extended from its secreted tube. The worm’s anterior end features a prominent branchial crown (radioles) used for respiration and filter feeding, while the long, segmented trunk shows annulations and musculature. The posterior end remains anchored within the coiled, protective tube, emphasizing its sessile lifestyle.

Commonly used in marine biology textbooks, academic presentations, and museum exhibits to illustrate invertebrate anatomy, especially for teaching about annelid adaptations, filter feeding, and tube-dwelling behavior. Matches user intent for educational, scientific, or taxonomic research on polychaetes.
