family VENERIDAE Rafinesque, 1815: cladomics
     31 genera

Cladomics Summary

number of species = 53 (53 total)
number of subtaxa (rank: genus) = 31
analyzed in 3 cladograms in 1 publication
maximum number of terminals in an analysis = 31 (mean = 11.33, median = 2)
maximum number of subtaxa (genus) = 16 (mean = 6.33, median = 2)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 2
maximum number of included terminals = 31, (mean = 16.5 median = 16.5)
maximum number of subtaxa (genus) = 16 (mean = 9, median = 9)
proportion of cladograms that support basic monophyly = 1
