This is a long sand-spit, c.35 km long, lying parallel to the coast, with the northern tip about 10 km south-west of Luanda. The area includes several small islands, one of which (the Ilha dos Passaros) lies between Mussulo and the mainland. The vegetation is dominated by mangroves (Rhizophora mangle, Laguncularia racemosa and Avicenna germinans), with low-growing saltmarshes (Sesuvium portulacastrum, S. mesembritemoides and Salicornia sp.) and intertidal flats (Loutchanski 199).
See Box for key species. The site is important for aquatic birds, with 61 congregatory waterbird species (42% of Angolan list) recorded, some of which occur in numbers which are at least nationally significant. Morus capensis and Sterna balaenarum are frequent to common non-breeding visitors to inshore waters. Some general studies of the avifauna have been carried out (Günther and Feiler 1986) and a project that focused on the food of two waders, Numenius arquata and N. phaeopus, was recently done by a student at the Universidade Agostinho Neto in Luanda (Loutchanski 1997).
