The aim of this study was to infer from allozyme data the phylogenetic relationships of nine species of actiniid sea anemones, and also use these data to assess the various methods (phenetic and cladistic) available for phylogenetic analysis. Starch gel electrophoresis was used to obtain genetic data from 13 gene loci.

Actinia equina, the beadlet sea anemone, is a very labile species, displaying variable colour patterns, broad habitat choice and diverse modes of reproduction. Historically, studies using genetic markers such as allozymes and differences in habitat choice lead several authors to propose that different colour morphs could represent different species ...

Anthopleura stellula (Actiniaria, Actiniidae) and its reproduction by transverse fission
Marine Biology, 1970Anthopleura stellulaEhrenberg 1834, a sea anemone from Eilat, Red Sea, is redescribed in detail and shown to be synonymous with Anthopleura elatensisEngland 1969. Asexual reproduction by autonomous transverse fission has been observed over a period of 8 months in A. stellula maintained in Mediterranean seawater (37.0 to 37.5‰ S).

The externally brooding sea anemone Cnidopus japonicus (Verrill) inhabits boulder shores between the mid-intertidal and shallow subtidal zones of Mutsu Bay, northern Japan. The anemones usually adhere to the side and under-surfaces of boulders. These anemones keep offspring on the middle part of their body wall during the breeding season.

The sea anemone Actinia equina was considered a highly variable species with a wide geographical distribution, but molecular systematic studies have shown that this wide distribution may be the result of the lumping of cryptic species. In this work enzyme electrophoresis was used to analyse the genetic variability of A.

Abstract The simplicity of a sea anemone polyp hinders the differences between species and populations, as very few external and internal morphological characters vary enough to distinguish closely related groups. Variations in size of different cnidocyst types could be an important way to characterize populations of sea anemones.

The results of an investigation into coelenteron content of the Antarctic sea anemoneUrticinopsis antarcticaCarlgren, 1927 are presented. Remains of invertebrate animals and fishes were found in the gastrovascular cavity of anemones. Some of them were damaged by digestion and were considered as food items ofU. antarctica.

This study performs a morphological and molecular characterization of the species belonging to the genus Aulactinia from Mar del Plata (Argentina), previously identified as A. marplatensis and A. reynaudi. The great similarity in the natural history of these species, and our results on external and internal anatomy, clearly suggests that the sea ...
