Ultrastructure of the dermal chromatophores in the Fringe-toed lizard, Acanthodactylus orientalis

Zoologia (Curitiba), 2017
Histology and electron microscopic studies of the dorsal skin of the Fringe-toed lizard, Acanthodactylus orientalis Angel, 1936, showed three types of dermal chromatophores: xanthophores, iridophores and melanophores. These pigment cells were observed in

Expression patterns of melanin-related genes are linked to crypsis and conspicuousness in a pumpkin toadlet. [PDF]

Mol Ecol
Abstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

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 ...

Genetic basis of orange spot formation in the guppy (Poecilia reticulata)

BMC Ecology and Evolution, 2021
Background To understand the evolutionary significance of female mate choice for colorful male ornamentation, the underlying regulatory mechanisms of such ornamentation must be understood for examining how the ornaments are associated with “male ...

Pax7 is required for establishment of the xanthophore lineage in zebrafish embryos

Molecular Biology of the Cell, 2016
The pigment pattern of many animal species is a result of the arrangement of different types of pigment-producing chromatophores. The zebrafish has three different types of chromatophores: black melanophores, yellow xanthophores, and shimmering iridophores arranged in a characteristic pattern of golden and blue horizontal stripes.

Bar, stripe and spot development in sand-dwelling cichlids from Lake Malawi

EvoDevo, 2019
Background Melanic patterns such as horizontal stripes, vertical bars and spots are common among teleost fishes and often serve roles in camouflage or mimicry. Extensive research in the zebrafish model has shown that the development of horizontal stripes

Lipid droplet biology and evolution illuminated by the characterization of a novel perilipin in teleost fish

eLife, 2017
Perilipin (PLIN) proteins constitute an ancient family important in lipid droplet (LD) formation and triglyceride metabolism. We identified an additional PLIN clade (plin6) that is unique to teleosts and can be traced to the two whole genome duplications

Ultrastructure of Erythrophores and Xanthophores of the Siamese Fighting Fish, Betta splendens [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2012
The ultrastructural morphology of brightly colored pigment cells (chromatophores) of Siamese fighting fish, Betta splendens, was investigated by transmission electron microscopy. The major pigment cells in the epidermis and dermis of the red and golden strains were erythrophores and xanthophores, respectively.

Evolution of Endothelin signaling and diversification of adult pigment pattern in Danio fishes. [PDF]

PLoS Genetics, 2018
Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying the evolution of adult form. Among these species, zebrafish D.
