Fig. 20. Tukey box plots of the number of branched anal-fin rays in species of Spintherobolus. Visual comparison of these box plots shows that the anal-fin ray counts of S. papilliferus are obviously different from all other species. Also, although there is overlap, the counts of S. broccae are obviously significantly different from those of S. leptoura and S. ankoseion. However, there were no significant differences between the counts of S. leptoura and S. ankoseion when subject to a Mann-Whitney rank-sum test.
