실험실내에서 곤봉히드라의 생활사를 조사하였다. 히드라는 생활사 중에 플라눌라 유생 단계와 해파리 단계가 있으나 곤봉히드라의 생활사에는 해파리 단계가 없고 플라눌라 유생 단계만 나타났다. 수정란으로부터 부화한 플라눌라 유생은 약 21시간동안 부착하는데 적합한 저질(substratum)을 찾아 배양기 바닥을 기어다니다가 고착한 다음, 폴립을 형성하였다.

The partial nucleotide sequences of 185 ribosomal RNA gene were compared for six cnidarian species (one belongs to class Hvdrozoa: Coryne pusilla. Five belong to class Anthozoa: Beflonella rigida from Octocorallia; Anemonia sulcutu, Anthopfeura kurognne, An thopleura midori from Hexacorallia: Cerianthus filiformis from Ceriantipatharial. The aligned sequence data were used to test the hypothesis on the anthozoan phylosenv by using the distance matrix method and parsimony method. The phvlosenetic inferences resulting from these methods indicate that the anthozoan is a monophvletic group and support the three subclass scheme (Octocorallia, HexBcorallia, Ceriantipatharial within class Anthozoa. The result also indicates that ceriantipatharian is more primitive than the other groups and that family Actiniidae is a monophvletic group within the anthozoan. However, the present analysis does not clearly indicate the phvlogenetic relationships of species among genera.
