Haliclona submonilifera, or the bubble bead sponge, is a deep-water demosponge from the continental shelf and slope off south-west Africa. [1]
This straw yellow sponge grows upright, with stalked branches that have numerous swellings and constrictions. These branches end with rounded ends with distinct oscules. Oscules may also occur on rounded elevations along the branches. The surface has a velventy texture. This sponge is very flexible and compressible and is easily torn. It typically grows up to 130 mm (5.1 in) tall and 70 mm (2.8 in). [1] It looks incredibly similar to Haliclona (Haliclona) urizae, another Namibian sponge species, but differs in having megascleres with blunt or rounded edges. More samples are needed to determine whether these are in actuality two different species or not. [2]
This species occurs along the continental shelf and slope off south-west Africa. [3] It is known to occur at depths from around 245 m (804 ft) off the coasts of Namibia and northern South Africa. [1] [3]
The lizard catshark is a small shark species of the catshark family, Scyliorhinidae, found off the coast of southern Brazil on the upper continental shelf at depths of between 250 and 500 metres.
The African sawtail catshark is a species of catshark, part of the family Scyliorhinidae. Demersal in nature, it is found at depths of 160–720 m (520–2,360 ft) off the western African coast from Morocco to South Africa. This slender species has a rather long, pointed snout, a series of dark saddles along the back and tail, and a prominent crest of enlarged dermal denticles along the upper edge of the caudal fin. Its maximum known length is 46 cm (18 in).
The orange wall sponge is a species of sea sponge belonging to the order Trachycladida. It is found in the south Atlantic and Indo-Pacific oceans. Around the South African coast, it is known from the Cape Peninsula to Cape Agulhas.
Haliclona anonyma, the turret sponge or tubular fan sponge, is a species of demosponge. It is endemic to South Africa, where it occurs between the Cape Peninsula and Sodwana Bay.

Genypterus capensis, commonly known as kingklip, is a species of cusk eel occurring along the Southern African coast from Walvis Bay in Namibia to Algoa Bay in South Africa. It is closely related to Genypterus blacodes from New Zealand. The species grows to a maximum length of 180 cm, a weight of 15.0 kg. It is one of the most popular fish items on South African menus. Despite appearances, it is not closely related to the eels of the order Anguilliformes.
