Tardigrade — Water Bear at 10:1 Optical Macro
122.13 $
A tardigrade (water bear) photographed at the limit of optical macro photography — the 0.5mm organism’s eight stubby legs, cylindrical body, and the characteristic mouth apparatus visible in the highest magnification achievable without electron microscopy.
Description
Tardigrade photography at 10:1 optical magnification pushes the resolution limit of optical macro systems — these 0.3 to 0.5mm organisms are at the exact scale where the finest optical macro equipment can resolve meaningful anatomical detail without requiring scanning electron microscopy. This image was made using a Canon MP-E 65mm lens at 5:1 and a 2× optical converter, achieving 10:1 reproduction. The tardigrade was sourced from a dried moss sample rehydrated to stimulate the active state from the cryptobiotic tun form. The image resolves the full external anatomy: the four pairs of stubby legs with their terminal claw clusters, the cylindrical body with its characteristic cross-sectional ribbing, and the anterior mouth apparatus with its stylet-bearing oral cone. Shot using phase contrast LED illumination through a cover slip, the internal organs — the muscular pharynx and the digestive tract — are visible through the translucent cuticle body wall.
