Fine structure of the eyes of jumping spiders

摘要: The four pairs of eyes in two species jumping spiders (Metaphidippus harfordi and Phidippus johnsoni) were studied by light electron microscopy. Unique features the anteromedial eyes, used acute vision, are: stratification receptors (basis color vision?); rhabdomeres anterior row planes perpendicular to each other perception polarized light?); surrounded extensions supportive cells containing a labyrinth cisternae (anatomical physiological support?); not individually shielded pigment (implementation high resolution?); lamination cornea green color?). Special lateral as wide-angle detectors movement, individual shielding receptor six arms pigmented (facilitating detection motion?); on axonlike fibers from sensory cell bodies situated outside eyecup; nonpigmented cells, filled with microtubules, enclose support?).
