WebIridophores are stacks of very thin cells that are capable of reflecting light back at different wavelengths (Cloney & Brocco, 1983) and possibly different polarities (Mathger & Hanlon, 2007).... WebJun 15, 2001 · The iridophores of the ventral side are orientated so that the blue-green light that enters the mantle cavity falls on them obliquely and so the light is channelled downwards by the ventral iridophores, which reflect light strongly at oblique angles of incidence. At normal incidence, at which reflectivity in the blue-green is low, the ... dhts the park https://mintpinkpenguin.com
