Figure 4 in Environmental control versus phylogenic fingerprint in ontogeny: The example of the development of the stalk in the genus Guillecrinus (stalked crinoids, Echinodermata)

Figure 4. Biometric profiles of the stalk of the juvenile specimens of Guillecrinus neocaledonicus. The numbers in circles refer to the symmetry of the articulations (for 5b, 5c, 39 see Figure 6). Dotted area with the single line defines transitional zone of mesistele; double vertical lines define the entire mesistele.
