The length can vary from 2 to 25 centimetres (0.8 to 9.8 in) with a tall slender habit to a short bushy habit. It is a coenocytic species that grows well in shallow protected areas with sandy bottoms.^[1]

Both coasts of Africa as far south as South Africa and many of the islands in Atlantic, Indian and Pacific Oceans. Found through much of Asia and in Australia it is found in Queensland^[3] and in Western Australia along the coast in a large area extending from around Perth then north through the Mid West and Pilbara coasts and into the Kimberley region.
