Morphometric patterns of two fouling Eudendrium spp. (Hydrozoa, Anthomedusae, Eudendriidae) from Sao Sebastiao (SP, SE Brazil)

Thirty colonies of Eudendrium carneum and 100 colonies of E. glomeratum, co llected on recruitment panels in Sao Sebastiao (SP, SE Brazil), were studie d concerning morphometrical parameters and compared with morphometrical dat a available from other locations. The results show that E. carneum from Bra zil has a relatively smaller morphometric variation than colonies of E. glo meratum for Brazil and other areas. Both morphological and speciation cause s are suggested as possible explanations for the high variation of E. glome ratum.
