Blue Chromatophores in Two Species of Callionymid Fish

  title={Blue Chromatophores in Two Species of Callionymid Fish},
  author={Makoto Goda and Ryozo Fujii},
Abstract Dendritic chromatophores that contained blue pigmentary organelles were found in the bluish parts of the skin of two callionymid species, the mandarin fish, Synchiropus splendidus, and the psychedelic fish, S. picturatus. We named these novel cells “cyanophores” and the organelles “cyanosomes”. In response to various stimulatory cues, the cyanophores responded by the aggregation or dispersion of cyanosomes. In addition to their role in the revelation of bluish hues, these cyanophores… 

Fluorescent Chromatophore Detected in the Guppy Poecilia reticulata

Differences in the occurence of fluorescent chromatophores among strains suggest that the formation of these chrom atophores is the result of genetic polymorphism.

Novel Dichromatic Chromatophores in the Integument of the Mandarin Fish Synchiropus splendidus

Novel light-absorbing dichromatic chromatophores are found in limited regions of the integument of the mandarin fish and pharmacological treatment with norepinephrine induced aggregation of both the erythrosomes and cyanosomes of the novel dichromatics possess motile activity, suggesting that they contribute to the role of their color changes observed in response to various environmental signals.

Brightly colored pigmentation in lower vertebrates: wonder searching its mechanisms and significance in the context of phylogeny.

A biographical sketch of the research and its related personal episodes with respect to brightly colored pigmentation in lower vertebrates and the personal affairs associated with the history of the Japanese community for pigment cell research were described.

Coloration and Chromatophores of the Domino Damsel, Dascyllus trimaculatus

The general background hue of the skin of the domino damsel (Dascyllus trimaculatus; Pomacentridae) is velvet-black, but three white spots form a characteristic, conspicuous pattern for this species.

Physiological and Morphological Color Changes in Teleosts and in Reptiles

This chapter explores the various studies on the morphological and/or physiological color changes in poikilothermic vertebrates, fish, and reptiles.

Ultrastructural and biochemical analysis of epidermal xanthophores and dermal chromatophores of the teleost Sparus aurata.

The pigmentary system of the teleost Sparus aurata skin is studied by electron microscopy and chromatographic analysis and the biochemical analysis did not establish any special characteristics: pteridine and flavin pigments located mostly in the pigmented dorsal region.

Development of Betta splendens embryos and larvae reveals variation in pigmentation patterns

Vertebrate pigmentation provides an ideal system for studying the intersections between evolution, genetics, and developmental biology and B. splendens has great potential as a model organism for pigmentation studies.

It is shown that the rapid color change from blue to red of the chameleon sand tilefish Hoplolatilus chlupatyi is mediated by adrenergic stimulation of a novel type of iridophore in which reflecting platelets are concentrated selectively in the periphery of the cell, near the plasma membrane.

Spectral Characteristics of Male Nuptial Coloration in Darters (Etheostoma)

By presenting preliminary descriptions of spectral properties of breeding males, this work provides a framework for further investigations into the evolution of breeding coloration and visual ecology in darters.
