Zooplankton Diagram - Types and Structures of Marine Microorganisms #213621 (License: Personal Use)

This black-and-white line drawing depicts six representative zooplankton organisms: Tintinnid (a ciliate with a lorica), Ostracod (a bivalved crustacean), Copepod (a dominant crustacean zooplankter), Planktonic Foraminifera (shelled protists with pseudopodia), By-the-Wind Sailor (a colonial siphonophore), and Arrow Worm (a predatory chaetognath). Each is rendered with anatomical precision to highlight distinguishing morphological traits used in marine biology identification.

Used in educational materials, textbooks, and marine science websites to teach students and researchers about plankton diversity; matches user intent for learning basic marine microorganism classification or preparing biology lesson content.
