Fig. 9

False-colored scanning electron microscopic images of heterotardigrades and eutardigrades. This figure follows the hypothesis for the homology of head sensory organs and head sensory fields by Gross et al. [20]. A heterotardigrade Echiniscus testudo. B eutardigrade Ramazzottius groenlandensis sp. nov. C eutardigrade Milnesium sp. D eutardigrade Paramacrobiotus areolatus. Colored area and dotted area mean head sensory organs and head sensory fields, respectively. Red: internal cirri & secondary clavae / frontal lobes / anterolateral sensory field (ASF). Blue: external cirri / anteroventral lobes (AVL) / cephalic papillae / ventrolateral sensory field (VSF). Yellow: median sensory field (MED) / centrodorsal organ (CO). Green: cirrus A & primary clava / elliptical organ (EO) / posterolateral sensory field (PSF)
