Thirty colonies of Eudendrium carneum and 100 colonies of E. glomeratum, collected on recruitment panels in São Sebastião (SP, SE Brazil), were studied concerning morphometrical parameters and compared with morphometrical data available from other locations. The results show that E. carneum from Brazil has a relatively smaller morphometric variation than colonies of E. glomeratum for Brazil and other areas. Both morphological and speciation causes are suggested as possible explanations for the high variation of E. glomeratum.
