Sample records for acochlidiid parhedyle cryptophthalma

  1. Keeping Nerves: Central Nervous System of the Interstitial Acochlidiid Parhedyle cryptophthalma (Gastropoda, Opisthobranchia)

    DEFF Research Database (Denmark)

    Joerger, Katharina; Kristof, Alen; Klussmann-Kolb, Annette;


    Unusually well-preserved fossils of a Halicyne-like cycloid crustacean frequently occur in the early Late Triassic lacustrine clay bed at Krasiejów in Opole Silesia, southern Poland. Its gill-like structures form a horseshoe-shaped pair of units composed of numerous calcified blades with reverse ...

  2. Redescription of the meiofaunal gastropod Parhedyle cryptophthalma, with focus on nervous system and sensory organs

    , integumental spicules, and aberrant radula morphology by light and scanning electron microscopy. Our focus was on the central nervous system and sensory organs, using 3D reconstruction based on serial semi-thin sections and immunocytochemistry (staining of FMRFamide and Tyrosine Hydroxylase) in conjunction......, rhinophoral, and pedal nerves and in single neurons in the anterior region of the foot sole. Central nervous and sensory features may greatly vary among acochlidians and other heterobranch taxa, and comprehensive comparative approaches are necessary to reveal their presence, function, homology, and evolution....
