Organism Chiton Acanthopleura granulata
Reference Speiser DI, Eernisse DJ, Johnsen S. A chiton uses aragonite lenses to form images. Curr Biol. 2011 Apr 26 21(8):665-70. doi: 10.1016/j.cub.2011.03.033 p.666 left column bottom paragraphPubMed ID21497091
Method P.666 left column bottom paragraph: "Next [investigators] evaluated A. granulata's eye morphology by combining light-microscope images of intact lenses (Figure 4A) and confocal images of sectioned eyes from decalcified samples (Figure 4B). [They] followed this approach because chiton lenses were too hard and brittle to section."
Comments P.666 left column bottom paragraph: "Pupil diameter was difficult to estimate from sectioned samples, but shell surface observations revealed that chiton eyes are 65–80 μm wide and have pupil diameters of 35–50 μm (Figure 1C)."
