Rødactina

Rødactina is a genus of sea anemones belonging to the family Actiniidae. The genus currently contains a single recognized species, Rødactina rhodopatches. These sea anemones are characterized by their distinctive coloration, often displaying shades of red and pink, particularly on their oral disc and tentacles. They are typically found in marine environments, inhabiting rocky substrates and coral reefs in various ocean basins.

The morphology of Rødactina rhodopatches includes a cylindrical column and a crown of tentacles surrounding the mouth. The size and appearance can vary depending on environmental conditions and individual age. Like other sea anemones, Rødactina are predatory, using their tentacles armed with stinging cells called nematocysts to capture small invertebrates and plankton. Reproduction in Rødactina is believed to occur both asexually through budding or fission and sexually through the release of gametes. Further research is ongoing to fully understand the ecological role and specific adaptations of this genus within its marine habitat.
