Journal of Fish Biology, Volume 109, Issue 1, Page 520-530, July 2026.Abstract A new species of the genus Tympanopleura is described from the Iquiri River, a tributary of the Ituxi River, a right‐bank tributary to the Purus River, Amazon River, northern Brazil. The new species is distinguished from all its congeners by a combination of features, such as the presence of an intensely pigmented square‐shaped blotch on the ...

Melanophore-Stimulating Substances in Amphibia
, 1963 A study of the Northwestern tiger salamander, Ambystoma tigrinum melanostictum (Baird), has confirmed a study of the Pacific tree frog, Hyla regilla, that a melanophore-stimulating substance is produced in the infundibulum of the embryo and young larva ...

The succession of cutaneous melanophore populations in Taricha torosa
, 1971 The normal developmental sequence of the dermal and epidermal melanophores in the California newt, Taricha torosa, with the first documentation of melanoblasts after hatching, is presented. It is shown that the first larval melanophore population of the

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

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.ABSTRACT The aim of this study was to provide an initial description of the embryology and larval development of Balistes capriscus species obtained from natural spawning in captivity. The study also aimed to assess the stocking density and the impact of offering four types of live food as the initial feed during the larviculture phase. Observations of

Melanophore integrity mutants show melanophore and iridophore defects.
, 2013 A, B) Dorsal, head images of live wildtype and mutant siblings, 5dpf. Wildtype melanophores maintain dark pigmentation and are now interacting with silver iridescent iridophores (present on eyes and in the center of caudal melanophore patch).
