It's not easy being green: Comparing typical skin colouration among amphibians with colour abnormalities associated with chromatophore deficits [PDF]
Ecology and EvolutionAmphibians can obtain their colour from a combination of several different pigment and light reflecting cell types called chromatophores, with defects in one or several of the cells leading to colour abnormalities. There is a need for better recording of

A new glassfrog species of the genus Centrolene (Amphibia, Anura, Centrolenidae) from Cordillera del Cóndor, southern Ecuador [PDF]
ZooKeys, 2023 Based on an integrative taxonomical approach, using molecular, morphological, and bioacoustics data, a new species of glassfrog of the genus Centrolene is described from Refugio de Vida Silvestre El Zarza, southern Ecuador. Centrolene zarza sp. nov. is a

Characterization of the Leucistic Texas Rat Snake Pantherophis obsoletus
Frontiers in Ecology and Evolution, 2021 Albinism and leucism are phenotypes resulting from impaired melanin pigmentation in the skin and skin appendages. However, melanin pigmentation of eyes remains unaffected in leucism.

Two new syntopic species of glassfrogs (Amphibia, Centrolenidae, Centrolene) from the southwestern Andes of Ecuador [PDF]
PeerJ, 2023 We describe two new species of glassfrogs of the genus Centrolene living in syntopy at La Enramada, province of Azuay, southwestern Ecuador. They were found in a small creek in montane evergreen forests at 2,900 m elevation.

DERMAL IRIDOPHORES IN SNAKES; CORRELATIONS WITH HABITAT ADAPTATION AND PHYLOGENY
, 1981 Deep continuous layers of iridophores were discovered in certain Asian Agkistrodon species. A survey of available snakes showed the banded iridophores to be present in North American Crotalus and Sistrurus also, indicating an unreported morphology to be ...

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.

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799). [PDF]
J Exp Zool A Ecol Integr PhysiolDehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Unmixing octopus camouflage by multispectral mapping of Octopus bimaculoides’ chromatic elements
Nanophotonics, 2021 Cephalopods camouflage abilities arise from highly specialized chromatic elements in their skin, chromatophores, iridophores, and leucophores, that enable them to display complex and rapidly changing color patterns.

ULTRASTRUCTURE OF A CEPHALOPOD PHOTOPHORE. II. IRIDOPHORES AS REFLECTORS AND TRANSMITTERS
The Biological Bulletin, 1974 The iridophores of one type of photophore of the deep sea squid, Pterygioteuthis microlampas were examined with the electron microscope and four different types were found. Three of these types have not been previously described. The regular iridophores of the posterior cup appear to be one-fourth wave length reflectors and redirect the light produced ...
