FIGURE 1 in Carlgren's hesitation allayed: redescription and systematics of Heteranthus verruculatus Klunzinger, 1877 (Cnidaria, Actiniaria), with a redefinition of Heteranthidae Carlgren, 1900
FIGURE 1 Maximum likelihood phylogram of sea anemones closely related to Heteranthus verruculatus. Topology presented consists of a concatenated dataset (i.e., cox3, 12S, 16S, 28S). Bootstrap resampling values under ML, and posterior probability values of Bayesian Inference (BI), are indicated at the branches as ML/BI. Only bootstrap values ≥50 and posterior probability ≥0.8 are shown; values <50 and <0.8 are indicated by (-). Text in parentheses are catalogue numbers for tissue samples of new sequences in this study (see supplementary table S1); (*) denotes H. verruculatus sample collected from Australia, previously published in González-Muñoz et al. (2015). For full tree, refer to supplementary fig. S2.
FIGURE 10 in Carlgren's hesitation allayed: redescription and systematics of Heteranthus verruculatus Klunzinger, 1877 (Cnidaria, Actiniaria), with a redefinition of Heteranthidae Carlgren, 1900
FIGURE 10 Distribution of Heteranthus verruculatus across the globe. 1. Oahu, Hawaii. 2. Rikitea, French Polynesia. 3. Kosseir, Egypt. 4. Bar Al Himan Peninsula, Oman. 5. Côn SƠn Island [= Poulo Condore], Vietnam. 6. Singapore. 7. Pulau Ambon, Indonesia. 8. Great Barrier Reef, Australia. 9. Moreton Bay, Australia. 10. Rottnest Island, Australia. Star symbols denote type localities for H. verruculatus (i.e., No. 3) and H. insignis [=H. verruculatus] (i.e., No. 5). Black dots represent sites where H. verruculatus was reported and/or collected. As den Hartog (1997) did not provide a specific locality within Indonesia for which H. verruculatus was encountered, it is not reflected on this map. An asterisk (*) beside each number reflects materials that have been examined in this study. All GPS co-ordinates associated with these materials are listed in supplementary table S2. See main text for full details.
FIGURE 4 A in Carlgren's hesitation allayed: redescription and systematics of Heteranthus verruculatus Klunzinger, 1877 (Cnidaria, Actiniaria), with a redefinition of Heteranthidae Carlgren, 1900
FIGURE 4 A clustering Heteranthus verruculatus (ZRC.CNI.1230) undergoing longitudinal fission. A, B. lateral stretching, with pedal-end extending the widest. Both column and pedal-ends inflate and deflate (arrowed) as the sea anemone pulls itself in opposite directions. C, D. column cleaved; continued stretching of actinopharynx that eventually splits, with distalmost end remaining (arrowed). E, F. pulling and splitting of the distalmost end of column where sphincter muscles are. Duration of observation is denoted at the top right-hand corner of each panel, time rendered in hours, minutes, and seconds (i.e., hh:mm:ss). Scale bar = 2 mm. Video screen capture by NWL Yap.
