The blastoporal organiser of a sea anemone [PDF]
SummaryIn 1924 Hilde Mangold and Hans Spemann transplanted the dorsal blastopore lip of an amphibian embryo to a host embryo's ventral side. This experiment revealed that the dorsal blastopore lip can act as an ‘organiser’ to induce a secondary body axis [1].

Molecular tuning of sea anemone stinging
AbstractJellyfish and sea anemones fire single-use, venom-covered barbs to immobilize prey or predators. We previously showed that the anemoneNematostella vectensisuses a specialized voltage-gated calcium (CaV) channel to trigger stinging in response to synergistic prey-derived chemicals and touch (Weir et al., 2020). Here we use experiments and theory

Boxer crabs induce asexual reproduction of their associated sea anemones by splitting and intraspecific theft [PDF]
Crabs of the genus Lybia have the remarkable habit of holding a sea anemone in each of their claws. This partnership appears to be obligate, at least on the part of the crab.

Sea anemone genomes reveal ancestral metazoan chromosomal macrosynteny
Draft genome sequences of non-bilaterian species have provided important insights into the evolution of the metazoan gene repertoire. However, there is little information about the evolution of gene clusters, genome architectures and karyotypes during ...

The 18S ribosomal RNA sequence of the sea anemone Ammonia sulcata and its evolutionary position among other eukaryotes [PDF]
Evolutionary trees based on partial small ribosomal subunit RNA sequences of 22 metazoa species have been published [(1988) Science 239, 748-753]. In these trees, cnidarians (Radiata) seemed to have evolved independently from the Bilateria, which is in ...

Novel in situ observations of asexual reproduction in the carpet sea anemone, Stichodactyla mertensii (Stichodactylidae, Actiniaria) [PDF]
Merten’s carpet sea anemone, Stichodactyla mertensii Brandt, 1835, is the largest known sea anemone species in the world, regularly exceeding one meter in oral disc diameter. A tropical species from the Indo-Pacific, S.
