Shifty Frogs: Evidence of Iridescence Among Amphibians
Austral Ecology, Volume 51, Issue 7, July 2026.ABSTRACT Iridescence is a striking optical phenomenon observed in some animals whereby colour or reflectivity changes based on viewing angle, such that two observers in different locations may simultaneously perceive the same tissue differently. Among amphibians, there is limited photographic evidence of tissues displaying colour shifts that define ...

Early development of Thyrsitops lepidopoides (Pisces: Gempylidae)
Brazilian Journal of Oceanography, 1986 Thyrsitops lepidopoides larvae were caught with Bongo nets in the upper 200 m of the ocean from the coast of southern Brazil during 1975-1978. Based on a serie of 271 specimens ranging from 2.5 to 24.0 mm body lenght, morphological and osteological ...

Journal of Fish Biology, Volume 109, Issue 1, Page 146-164, July 2026.Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Assessing Colouration in Ichthyology: Insights from the Melanophore Index Perspective
Fish colouration significantly influences various aspects of their biology, including communication, camouflage, and mate selection. Among the pigment cells responsible for generating colours, melanophores are particularly significant due to their ...

The Reactions of the Melanophores of the Horned Toad [PDF]
Proceedings of the National Academy of Sciences, 1917 observing the initial and the later phases of phosphorescence there would be an actual discontinuity between the processes referred to above and those in the curves for the phosphorescence of slow decay. Summary.-(1) The regions of selective excitation (the bands of excitation) for the Lenard and Klatt sulphides are shown to coincide in position and ...

Journal of Fish Biology, Volume 109, Issue 1, Page 599-604, July 2026.Abstract Coryphaenoides Gunnerus, 1765 comprises 66 valid species of deep‐sea fishes commonly known as grenadiers, with 6 previously reported from Brazilian waters. Here, we make the first records for Coryphaenoides striaturus and Coryphaenoides subserrulatus on the Brazilian continental slope. Both species are distributed in the subtropical regions of

Coordinated regulation of chromatophore differentiation and melanogenesis during the ontogeny of skin pigmentation of Solea senegalensis (Kaup, 1858). [PDF]
PLoS ONE, 2013 Abnormal pigmentation of Senegalese sole has been described as one problem facing the full exploitation of its commercial production. To improve our understanding of flatfish pigmentation of this commercially important species we have evaluated eleven ...

Journal of Fish Biology, Volume 109, Issue 1, Page 371-383, July 2026.Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Pattern features of zebrafish upon varying long-range interaction scale in melanophore cell birth
, 2020 We provide summary pattern features of model simulations of wild-type, shady, and pfeffer zebrafish patterns generated using the agent-based model from "Volkening A and Sandstede B (2018) Iridophores as a source of robustness in zebrafish stripes and ...
