Sexual dimorphism in fin size and shape in bluefin killfish

These data accompany the analysis of sexual dimorphism in fin size in bluefin killifish. In this study, we quantified sexual dimorphism in fin size and shape across all fin types in the bluefin killifish, Lucania goodei. We found striking sexual dimorphism in the dorsal and anal fins, particularly in area, ray length, and base length. In contrast, the pelvic, pectoral, and caudal fins showed moderate, but detectable, levels of dimorphism. The package contains data on fin ray number, fin ray lengths, fin area, and fin base length for dorsal, anal, caudal, pectoral, and pelvic fins of male and female blufin killifish. , , # Sexual dimorphism in fin size and shape in bluefin killfish

## Description of the data and file structure

Bluefin killifish were collected from two populations in Florida (Everglades and Rainbow River) and maintained in lab colonies. Approximately 10 males and 10 females from each population were euthanized and photographed so that morphometric data could be measured from the images using NIH Image.
### Files and variables

#### File: Brockelsby_etal_code.R

**Description:** This file contains the code to analyze the data below. It estimates the repeatability of traits, correlations of traits with standard length, the effects of sex (and population) on trait values, estimates sexual dimorphism, coefficients of variation for traits, and correlations among trait values for both males and females.

#### File: SL_correct.csv

**Description:** This file contains data on the standard length for each individual fish. Fish.ID...,
