Influence of Tank Coloration in Modulating Physiological Growth, Survival and Skin Pigmentation Expression in Nursery‐Reared Channa striata

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Tank colour is a crucial environmental factor that influences growth performance; however, its effect on Channa striata fry under laboratory environments is not widely recognized. This study investigated the influence of tank coloration on growth, survival, cannibalism, and pigmentation of C. striata larvae under nursery rearing conditions.

Leucism recording and skin alterations in the Arabian tadpole (Sclerophrys arabica) (Heyden, 1827) in AlUla, Saudi Arabia

open access: yesThe European Zoological Journal
Leucism is a colour aberration that results from a lack of melanin and alteration in the development or distribution of chromophores. The study records for the first time the occurrence of leucistic larvae of Arabian toad (Sclerophrys arabica) in AlUla ...

Larval Pigmentation Reveals Environmental and Genetic Influences in Hybridizing Ambystoma Salamanders

open access: yesEcology and Evolution
Closely related species may produce hybrids, and these hybrids often display intermediate traits that can influence fitness and reproductive isolation. In this study, we examine Ambystoma barbouri and Ambystoma texanum, two sister salamander species that

Dynamic pigmentary and structural coloration within cephalopod chromatophore organs

open access: yesNature Communications, 2019
Chromatophores in cephalopod skin are known for fast changes in coloration due to light-scattering pigment granules. Here, authors demonstrate structural coloration facilitated by reflectin in sheath cells and offer insights into the interplay between ...
