PLOS One | https://doi.org/10.1371/journal.pone.0326053 June 20, 2025 13 / 29 Fig 6. Heatmaps illustrating intraspecies and intraspecimen ASV patterns in Spumellaria. ASV presence and relative read abundance are shown for each group of morphospecies or morphotaxa: Dictyocoryne (a); Didymocyrtis (b); Euchitonia elegans-furcata (c); and other Spumellaria (d). Morpho- logical classifications of each specimen are shown on the y-axis of each heatmap with a random numeric identifier. Juvenile specimens were classified
