anatomical anomaly 3d model

Realistic 3D model of a small deformed preserved specimen, optimized for 3D printing. Single organism with one main spine, irregular and twisted, partially splitting near the upper body into two asymmetrical heads. Heads are uneven, one larger and more developed, not mirrored, slightly malformed. Body elongated but compact and partially coiled, compressed as if preserved inside a jar. Structure biologically wrong but plausible, not clean or symmetrical. Subtle partial rib structures, uneven and irregular. Surface rough, aged, imperfect, with asymmetry and small deformities, no smooth or ideal anatomy. Pose low and curved, not vertical. Style realistic, disturbing, like an anatomical anomaly, not fantasy. All parts connected, slightly thickened for print stability. Clean manifold watertight mesh, solid volume. Neutral lighting, plain background, STL ready.
