We will investigate the divergent mode of stripe formation in the fins and the molecular influence of the cellular environment on chromatophore interactions.
Each chromatophore stores pigment of a particular colour and can be broadly and flatly expanded (enhancing its colour) or greatly contracted (minimising its colour) via voluntary muscle cells (Ruppert and Barnes 1994; Norman 2000).
A detailed description of the chromatophores of fish larvae is important, as each species has a distinct pattern and location of chromatophore pigmentation that can be used in identification (Kendall, Ahlstrom, & Moser, 1984).
Although major physiological actions of SL remain an interesting yet unresolved issue, direct evidences from mutant of medaka [14-16] and "cobalt" rainbow trout [17,18] support the concept that major functions of SL are involved in chromatophore regulation and lipid metabolism.
Blue king crab undergo a diapause stage that lasts for approximately 2 months (Stevens, 2006) between the stages of chromatophore formation and eye enlargement (approximately equivalent to our stages 9 and 10).
The pigment in the chromatophore cell in the octopus causes it to change colour.
In addition, different types of chromatophores can be positioned adjacent to each other forming "chromatophore units".
What do chromatophore cells in the skins of animals enable them to do?
The new approach, by contrast, is built on the unusual characteristics of certain chromatophore or pigment-bearing cells, called erythrophores, from Siamese fighting fish.
Twenty-four hours later, these animals were clearly infected, showing fragile antennas and soft cuticle as well as chromatophore expansion along the whole surface of the body, particularly at the tail fan (telson and uropods).
Morphological characters associated with metamorphosis included a flexed notochord, fully developed fin rays, a pronounced chromatophore at the base of the caudal fin, and well developed teeth.
Among the limited number of morphological characteristics, chromatophore pigmentation pattern and arrangement is regarded as the most effective criterion for morphological identification of polydorid larvae (Blake and Woodwick, 1975; Day and Blake, 1979; Radashevsky, 2005).
