Principle component analysis of transcriptome expression data. Transcriptome expression data was filtered to include only transcripts which exceed 3 RLE (n = 96,534). In the legend, numerical labels (green and red) define the phyllosoma stages, which conclude with gut-retraction (GR) as phyllosoma metamorphosis is initiated. Three puerulus stages follow, and then finally two juvenile stages (Juv-n). Labels appended with -n denotes n days post-molt. The blue line connecting each cluster indicates the temporal sequence of stages, with blue arrows indicating direction
