Document Summary
Today: function of colour (patternsome sh may not actually see colour) At sh: can change pattern very quickly. Melanin: melanophores get lled up with pigment, deeper in skin= innervation which cause pigment to expand/contract quickly thus movement of melanin changes colour pattern of sh. Match the background spectral radiance(?) (background matches) Eyed ounder: can change colour very quickly-changes body in seconds. Can match background pattern, even subtle details via vision. The two that roughly match ( ounder): water murky, a lot of green space light-don t need to match water well because can t see them as easily. The one that matches well (eyed ounder): water clear. Eye bars- bar that covers the eye - masks the eye (not entirely sure) I. e. gobi some eye bars yellow, doesn t mask, whats the function?- don t know. Counter shading- dark on top, silvery-light on sides & the bottom i. e. pelage sh.
