This new model suggests that one of the pigment cell types - called iridophores - leads the process of cell organization.
A pairwise comparison test showed that mean durations were significantly higher in the most enduring components, such as clear, iridophore splotches, and bands (P < 0.05), than in the most short-lived components: arm spots, lateral mantle spot in females, fin stripe, accentuated oviducal gland, lateral mantle streaks, and dark dorsal stripe (Fig.
Changes in spectral rellexions from the iridophore of neon tetra.
Microscopic examination of skin tissue at these locations revealed the existence of a new type of iridophore. These reflecting cells were located in very narrow areas of the skin 60 [+ or -] 26 [micro]m (n = 24) underneath the skin surface, and organized as long stripes.
2B), the translucence renders the squid cryptic, or camouflaged, and often the Dorsal iridophore splotches are expressed simultaneously.
Other areas on the squid that reflected partially linearly polarized light were the "Dorsal iridophore splotches" on the mantle, but this reflection had partial polarization of less then 0.5.
Biochemical characterization crystals from the dermal iridophores of a chameleon Anolis carolinesis.
For instance, the researchers say that the "run-and-chase" behavior of black and yellow cells accounts for stripes on zebrafish bodies as well as their fins, but she has evidence that iridescent cells called iridophores are also important for body stripes.
Color changes in teleosts are due to the aggregation/dispersion of pigment within the light-absorbing chromatophores, in particular to the motile activity of melanosomes, and to the reflecting changes in active iridophores (Beeching 1995, Fujii et al.
Complete albinism is expressed as a lack of integumentary and retinal melanin, however, true albinos can exhibit integumentary coloration due to the other types of chromatophores: xanthophores and iridophores (CLARK, 2002).
Fine silvery shiny iridophores cover most of the dorsum in loose groups, the eyeballs, and the ventrolateral parts of the body.
