Spiralian Model Systems

Edited by: Jonathan Henry

Cover Legend

The cover shows a diverse array of adult bodyplans found amongst the Spiralia. Images courtesy of Drs. Michael LaBarbera, Aldine Amiel, and Eric Röddinger. The three sepia line drawings are from Edwin G. Conklin’s 1897 monograph on “The embryology of Crepidula” (J. Morphol. 13: 1-226) and show spiral cleavage, a synapomorphic trait exhibited by many members of this clade. To the right of those drawings are corresponding modern fluorescence images showing in vivo expression of Histone-H2B-mCherry to label chromosomes/nuclei (red/yellow), and tubulin-GFP to label microtubules (green). Fluorescence images courtesy of Drs. Deirdre Lyons and Jonathan Henry. For further details about each of the animals shown here, see the legend for Figure 2 in the paper by Jonathan Henry in this issue, pp. 389-401.
