Diadumenidae
Diadumenidae is a family of sea anemones within the order Actiniaria. They are distinguished by their distinctive appearance, including a column that is typically smooth and lacks verrucae (wart-like bumps). They are found in a wide range of marine environments, including rocky shores, coral reefs, and sandy bottoms.
Common Names
Sea anemones in the family Diadumenidae are commonly known as "ringed anemones" due to the series of rings or bands that encircle their column.
Characteristics
Members of the Diadumenidae family share several key characteristics:
- Smooth column: Their column is typically smooth and lacks verrucae. This sets them apart from many other sea anemone families.
- Ringed appearance: The column is adorned with rings or bands, which may be colored or textured differently from the rest of the column.
- Acroporid symbiosis: Some species, like Diadumene lineata, exhibit a symbiotic relationship with certain corals, specifically those belonging to the genus Acropora. They often live within the branches of these corals.
- Size and form: They can range in size from small and slender to larger, more robust individuals. Their body shapes can vary, with some species having a more elongated column and others having a more squat appearance.
Environment
Diadumenidae sea anemones are found in a diverse array of marine habitats, including:
- Rocky shores: They often inhabit crevices and rocky overhangs, seeking protection from strong currents and waves.
- Coral reefs: Certain species, like Diadumene lineata, are frequently observed on coral reefs, often in association with branching corals.
- Sandy bottoms: Some species can be found burrowed in sandy substrates, extending their tentacles to capture prey.
