Permanently preserved in a crystal-clear, optical-grade acrylic resin block (140 × 64 × 24 mm), this authentic biological preparation presents 3 quintessential real annelid specimens arranged horizontally in parallel comparative display. Prominently titled \\\"Annelid Representatives\\\" across the top, the specimen features clear numerical labels (1 through 3) that systematically showcase the major evolutionary classes of true coelomate segmented worms: the terrestrial oligochaete earthworm (1, showing cylindrical hydrostatic segmentation and clitellum), the ectoparasitic hirudinean leech (2, showing dorsoventrally flattened body, anterior\/posterior attachment suckers, and external annuli), and the marine polychaete clamworm \/ ragworm (3, displaying prominent lateral parapodia equipped with chitinous swimming and sensory setae). Encased permanently in solid, durable acrylic, this museum-grade teaching specimen delivers 360-degree, distortion-free viewing of soft-bodied metameric anatomy without preservation liquids, shrinking, alcohol fumes, or delicate specimen degradation. An essential hands-on learning resource for invertebrate zoology lectures, marine biology classrooms, STEM science curricula, and naturalist curio collections.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWHY YOU'LL LOVE IT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eAuthentic Comparative Annelida Specimens\u003c\/strong\u003e – Preserves 3 genuine segmented worms (earthworm, leech, and marine polychaete clamworm) in optical resin.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003e3 Systematic Representative Labels (1–3)\u003c\/strong\u003e – Sequential numbers guide clear classroom identification of Oligochaeta, Hirudinea, and Polychaeta classes.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eClear Metameric \u0026amp; Locomotory Detail\u003c\/strong\u003e – Delivers magnified observation of hydrostatic segment rings, anterior\/posterior suckers, and bristled lateral parapodia.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eThree Major Ecological Niches\u003c\/strong\u003e – Directly compares terrestrial burrowing, aquatic parasitic, and marine benthic segmented worm adaptations side-by-side.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eOptical-Grade Acrylic Monolith\u003c\/strong\u003e – Solid 140 × 64 × 24 mm transparent resin block enables complete 360-degree study from every angle.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003ePermanent, Clean \u0026amp; Odorless\u003c\/strong\u003e – Durable acrylic casing seals delicate soft-bodied organisms forever, eliminating formalin jars and fragile handling.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eEssential Invertebrate Biology Resource\u003c\/strong\u003e – An ideal hands-on visual aid for biology educators, zoology students, nature centers, and worm collectors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003ePERFECT FOR\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eZoologists, marine and freshwater biology educators, high school and university science labs, STEM students, nature centers, and distinctive natural history gift collections.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e E1605\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecimen:\u003c\/strong\u003e 3 Types of Real Annelids: Earthworm (Oligochaeta), Leech (Hirudinea), Clamworm (Polychaeta) \/ Phylum Annelida\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Optical-Grade Acrylic Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 140 × 64 × 24 mm (approx. 5.5 × 2.5 × 0.9 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Crystal Clear with Natural Specimens\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Horizontal Rectangular Block with Numbered Labels (1–3)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e*Notice: Price is for retail.
