SEA SAPPHIREAn interpretation of the crustacean
Sapphirina Copepod and its light
reflectance via shell structure
Research• Carl Claus (1835-1899)• Zoologist• Univ. Vienna
• Weizman Inst. & Interuniversity institue for Marine Sciences
• -located in israel
Copepod• Crustaceans• Metazoan• Genus: sapphrinia copepod• Symbiotic• Eat mosquito larvae• Length: 0.2-2mm (some up to 10mm)
Why do they shine?
• Covered with chitin• Guanine Crystals (hexagonal
structure)• Cytoplasm separates the layers• Thickness of cytoplasm and light
angle• Spacing: 4/10th of a mm• Structural coloration
Location
• Africa• Rhode Island• California Preferred Locations: freshwater or hypersaline environments
Importance/significance• Shells and scales used for pearly
iridescence features in shampoos,cosmetics and paint.
• Future: to be used for optical technologies such as optical displays and mirrors.
