Knobbly anemone (Bunodosoma capense)

Details of the tentacles and the papillae. Mouille Point, Cape Town, Western Cape (2020) – iNaturalist

Previously known as Bunodosoma capensis.

Column streaked with small non-adhesive knobs, called papillae. Up to 96 spherules present in fosse.
Papillae are usually darker and brighter in contrast with the background colour, which can be cream-white, pink, orange, red, blue or purple, sometimes mottled.

Generally 20 to 40 mm in diameter.

A strikingly variable species, abundant in sand-free pools and reefs. Often found attached to mussels or red bait. Sand never adheres to the column, which distinguishes it from the sandy anemone (Bunodactis reynaudi).
