Phylogenetic context and comparison of two hydrothermal vent endemic gastropods: Chrysomallon (upper) and Gigantopelta (lower). a. Consensus tree reconstructed using Bayesian inference from a combined analysis of five standard markers (H3, COI, 16S, 18S, 28S), total alignment length 2753-bp. Node values indicate Bayesian posterior probability. b. Chrysomallon squamiferum (Longqi field, Southwest Indian Ridge) adult specimen in exterior ventral view and, c. transverse section showing internal oesophageal glad (og), scale bars 1 cm. d. Gigantopelta chessoia (E2 Segment, East Scotia Ridge, Southern Ocean) adult specimen, and e. transverse section showing internal oesophageal glad (og), scale bars 1 cm. Abbreviations: ct, ctenidium; pm, pedal muscle; og, oesophageal gland; sc, scales; si, blood sinus; te, testis
