Exosphaeroma laeviusculum is a species of isopod in the family Sphaeromatidae, [2] native to the west coast of southern Africa.
Exosphaeroma laeviusculum has a flattened body with speckled pattern of black and white, or pink. The pleon consists of a single segment, although the original fused segments are still discernible by lateral grooves. The telson is triangular, bears two small ridges near the base and a semicircle of tiny tubercles. Average body length is 10 mm. [3]
The species occurs on the west coast of southern Africa, from Lüderitz in Namibia to Cape Point in South Africa. [3] [4] It inhabits the intertidal zone or shallow water, where it may be found among weeds or under stones. [3]
For unknown reasons, the original description by Camill Heller reports the type locality as "Java". [1] [2]
Isopoda is an order of crustaceans. Members of this group are called isopods and include both aquatic species, and terrestrial species such as woodlice. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax called the marsupium.
Iais pubescens is a species of marine isopod in the family Janiridae. It inhabits seashores in a large number of locations in the southern hemisphere and may be found both free-living, and as commensals on larger isopods.
Macropodia falcifera, the Cape long-legged spider crab, is a species of marine crab found around the South African coast. It is a member of the family Inachidae.
Clinus acuminatus, the sad klipfish, is a species of fish in the family Clinidae. It is endemic to Southern Africa, where it occurs along the coast of Namibia and South Africa. It can reach a maximum length of 13 centimetres (5.1 in) TL and is viviparous. The sad klipfish feeds on crustaceans.
Clinus venustris, the speckled klipfish, is a species of clinid that occurs in subtropical waters of the Atlantic Ocean from Namibia to South Africa where it is found in the subtidal zone as well as being a denizen of tide pools. This species can reach a maximum length of 12 centimetres (4.7 in) TL. and feeds primarily on amphipods, isopods, mysids, and echinoderms.
Ligia dilatata is a woodlouse in the family Ligiidae.
Uromunna sheltoni is a species of isopod first described by Brian Kensley in 1977. U. sheltoni is included in the genus Uromunna and family Munnidae. No subspecies are listed. The species was first collected by Peter Shelton of the University of Cape Town, for whom it is named.
Exosphaeroma is a genus of marine isopod of the family Sphaeromatidae. This genus is found in shallow ocean waters worldwide. It is notable for being one of the few genera of sphaeromatid to be found in the southern reaches of the Southern Ocean. The greatest diversity of Exosphaeroma occurs in the Southern Hemisphere.
Ischnochiton oniscus, the dwarf chiton, is a small polyplacophoran mollusc in the family Ischnochitonidae, endemic to the coast of southern Africa.
Ischnochiton bergoti, the ribbed-scale chiton, is a small polyplacophoran mollusc in the family Ischnochitonidae, endemic to the west coast of southern Africa.

Radsia nigrovirescens, the brooding chiton, is a small polyplacophoran mollusc in the family Chitonidae, found on the west coast of southern Africa.
Anilocra capensis is a species of parasitic isopod in the family Cymothoidae. It is endemic to southern Africa. The species preferentially attaches itself to the hottentot seabream.
Pachymetopon blochii, the hottentot seabream or hottentot, is a species of sea bream in the family Sparidae, native to the southwestern coast of Africa.
Glyptidotea is a monotypic genus of isopod in the family Idoteidae. Its sole member is Glyptidotea lichtensteini, the keeled isopod, a medium-sized isopod found on the coast of southern Africa.
Deto echinata, the horned isopod, is a species of air-breathing isopod, or woodlouse, in the family Detonidae. It inhabits seashores in southern Africa and on some oceanic islands.
The Marine biodiversity of South Africa is the variety of living organisms that live in the seas off the coast of South Africa. It includes genetic, species and ecosystems biodiversity in a range of habitats spread over a range of ecologically varied regions, influenced by the geomorphology of the seabed and circulation of major and local water masses, which distribute both living organisms and nutrients in complex and time-variable patterns.
Booposoidea is a monospecific genus of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. The only species in the genus is Boopsoidea inornata, the Fransmadam or Karel grootoog, which is endemic to the southwestern Indian Ocean off South Africa.
