FIGURE 6 in Taxonomy of Rhabderemia Topsent, 1890 collected from the southeastern Brazilian continental shelf and slope by Programme REVIZEE (Rhabderemiidae, Poecilosclerida, Demospongiae), with the description of two new species

FIGURE 6. Possible reconstruction of ancestral habitat preferences mapped on Van Soest & Hooper´s (1993) phylogeny of Rhabderemia. The two new species described here were attached to their likely positions (dotted lines) based on morphologic affinity, as discussed in the text. Stout black lines = deep­water species and likely deep­water ancestors. Stout gray lines = shallow­water species and likely shallow­water ancestors. Slender black lines = species for which depth was not recorded or uncertain ancestral assignments. Arrows indicate likely events of deep­water invasion.
