Appearance and lifestyle:
Knobbly anemones (Bunodosoma capensis) are visually very variable. They can be white, maroon, pink, red, blue, purple or orange. Their central column is lined with a series of small, usually purple, knobs that are small and more darkly coloured than the rest of the body. These knobs are not sticky; sand and debris do not stick to the column of knobbly anemones.
Habitat:
They are found on the southern African coast from Namibia to KwaZulu-Natal. They inhabit sand-free rockpools and rocky reefs where they often stick to filter-feeding invertebrates such as redbait or mussels.
Diet:
They feed on small fish, plankton, and invertebrates.
Threats:
Pollution, climate change, habitat disturbance etc.
Grows to 10cm in diameter.
