The biology of iridophores in reptiles [PDF]
, 1993 Ph.D. University of Kansas, Physiology and Cell Biology 1993Tissue color can have multiple functions in reptiles. Bright ventral color patches are thought to be primarily involved in intraspecific signaling of social status.

Changes in spectral reflexions from the iridophores of the neon tetra. [PDF]
The Journal of Physiology, 1982 1. The iridescent stripe of the freshwater teleost, the neon tetra, changes from green in the daytime to violet‐blue at night. 2. Spectral reflectance measurements were used to follow these colour changes. 3. Light causes a shift in reflectance to longer wavelengths in living fish and in isolated tissue from the lateral stripe.

Aggregate, Volume 7, Issue 9, September 2026.Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

Journal of Comparative Neurology, Volume 534, Issue 9, September 2026.The annual turquoise killifish (Nothobranchius furzeri) cone photoreceptor mosaic is an ordered lattice but lacks regularity of cone subtypes in adulthood. The cone mosaic differs between life stages and has characteristics observed in other fishes adapted for life in turbid water.

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 6, Page 475-486, September 2026.Classical approaches for coloration analysis are limited by human low‐resolution phenotyping and genetic analysis. Artificial intelligence allows us to find genes beyond the tip of the iceberg that explain color and pattern diversity in nature. ABSTRACT Pigmentation has long served as a powerful system for exploring gene–trait relationships, yet much ...

eLife, 2014 Interactions between all three pigment cell types are required to form the stripe pattern of adult zebrafish (Danio rerio), but their molecular nature is poorly understood.

Advanced Science, 2022 The ability of some animals to rapidly change their colors can greatly improve their chances of escaping predators or hunting prey. A classic example is cephalopods, which can rapidly shift through a wide range of colors.

Journal of Morphology, Volume 287, Issue 9, September 2026.Using micro computed tomography, light microscopy and transmission electron microscopy, this study reveals that the conjunctival portions of the corneal epithelial and spectacular endothelial lining in the eye of the short‐nosed sea snake Aipysurus apraefrontalis possess high densities of microvilli to increase the surface area and two types of ...

Control Strategies in Guanine Biocrystallization
Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Multiple pigment cell types contribute to the black, blue, and orange ornaments of male guppies (Poecilia reticulata). [PDF]
PLoS ONE, 2014 The fitness of male guppies (Poecilia reticulata) highly depends on the size and number of their black, blue, and orange ornaments. Recently, progress has been made regarding the genetic mechanisms underlying male guppy pigment pattern formation, but we ...
