Structure and optics of the eyes of the box jellyfish Chiropsella bronzie.

摘要: Cubomedusae have a total of 24 eyes four morphologically different types. Two these eye types are camera-type (upper and lower lens-eye), while the other two simpler pigment pit (pit slit eye). Here, we give description visual system box jellyfish species Chiropsella bronzie optics lens in this species. One aim study is to distinguish between general cubozoan features species-specific layout eyes. We find that both more severely under-focused C. than those previously investigated Tripedalia cystophora. In lens-eye bronzie, blur circles subtend 20 52 degrees for closed open pupil, respectively, effectively removing all but coarsest structures image. Histology reveals retina lens-eye, addition pigmented photoreceptors, also contains long pigment-cells, with dark white pigment, where migrates on light/dark adaptation. Unlike upper T.cystophora, same C.bronzie did not display any significant optical power.
