Table 2 Summary of distinguishing characteristics among the three Alviniconcha spp.

From: Classical and computed tomographic anatomical analyses in a not-so-cryptic Alviniconcha species complex from hydrothermal vents in the SW Pacific

  1. Species were readily distinguishable based on periostraca. BL bristle length, RT rachidian, LT Lateral teeth. Mean BL calculated based on lengths from 10 individuals of A. kojimai and A. boucheti and 5 individuals of A. strummeri (based on three replicates ea.). *A fourth 2° bristle can occur in A. kojimai, very occasionally and sporadically. † Photo is of an alcohol-fixed specimen (other photos from frozen specimens)
