Authors: Matthew T Wayland Data type: morphological and meristic Comma separated value (csv) file of morphometric data from females. Rows are specimens and columns (column three onwards) are morphometric variables (e.g. proboscis length) or meristic variables (e.g. number of longitudinal rows of hooks). All morphometric measurements are in micrometres. The first column is species and the second column is a unique identifier for the specimen. The unique identifier is composed of two parts: the part before the full stop indicates the sample (please see table 1); the number after the full stop indicates the specimen number. In the species column, Echinorhynchus bothniensis and Echinorhynchus \'bothniensis\' are listed as bothniensis1 and bothniensis2, respectively. File name: female_morphometrics.csv
