Abstract

The different chromatophores of the ectoderm can be classified according to the chemical structure of pigments and their spectral properties (Table 1). Pterin-derivatives are found as a major pigment in a subclass of chromatophores that was previously observed only in the ectoderm of poikilotherms, crustaceae and cephalopods. It is characteristic of these cells that pterins are bound to cytoplasmic particles (pterinosomes) of about 0.5 μm in diameter (2). Equivalent organelles have never been confirmed in any ectodermal cells of higher vertebrates.
