FIGURE 1. Maximum likelihood phylogeny of the 28S locus. Genbank accession numbers and collection locations (when known) are shown; bold indicates new sequences. Asterisks at nodes indicate SH-aLRT ≥ 80% and UFbootstrap ≥ 95%. Scale bar indicates substitutions per site. Asterisks in node names indicate type species of a genus.

FIGURE 2. Maximum likelihood phylogeny of the cox1 locus. Genbank accession numbers and collection locations (when known) are shown; bold indicates new sequences. Asterisks at nodes indicate SH-aLRT ≥ 80% and UFbootstrap ≥ 95%. Scale bar indicates substitutions per site. Asterisks in node names indicate type species of a genus.

FIGURE 8. Rhizaxinella gadus. A: Whale-fall where SIO-BIC P1999 was collected. B: Soft-sediment where P2000 was collected; when disturbed by the slurp tube, all stalked sponges in this photo were revealed to be connected below the sediment by branched stalks. C: DDT-barrel dump site where SIO-BIC P2015 was collected. D: Cross-section of SIO-BIC P1999 showing ectosomal spicule bouquets and confused choanosomal skeleton. E: Cross-section of SIO-BIC P2016 showing confused spicules and spicule bundles in choanosome. F: tylostyle from SIO-BIC P1999.
