The grey fan hydroid (Solanderia procumbens) is a large colonial hydroid in the family Solanderiidae. [1]
The grey fan hydroid grows as a grey to dark brown fan-shaped colony that may be 40 cm in total height. It has variable branching in a single plane. The main stem of old colonies can be quite thick and flattened in the plane of branching. Smaller branches are round in section. Hydranths are scattered irregularly on the stem and branches. [2]
This colonial animal is found only around the South African coast from the Atlantic side of the Cape Peninsula to KwaZulu-Natal in 10-130m under water. [2]
Gonophores (reproductive structures) are irregularly spaced on the branches and are rounded with short stalks. [2]
Clinus brevicristatus, the Cape klipfish, is a species of clinid that occurs in subtropical waters of the Atlantic Ocean around South Africa where it prefers habitats with plentiful growth of seaweed. This species can reach a maximum length of 12 centimetres (4.7 in) TL.
Mimetes fimbriifolius, also called cowl pagoda or the fringed pagoda, is a species of plant in the family Proteaceae. It is a dense, rounded, multi-branched tree that grows up to 4 metres in height. This attractive and striking plant flowers all year round, and produces red and yellow branch-heads and inflorescences. The nectar-rich flowers are pollinated by sunbirds and the seeds are distributed and taken underground by ants before germinating. It is endemic to the Table Mountain range in the city of Cape Town, South Africa.

Obelia longissima is a colonial species of hydrozoan in the order Leptomedusae. Its hydroid form grows as feathery stems resembling seaweed from a basal stolon. It is found in many temperate and cold seas world-wide but is absent from the tropics.

Pycnotheca mirabilis, The feathery hydroid, is a colonial hydroid in the family Kirchenpaueriidae. Feathery hydroids are often white and grow in crowded colonies resembling upright feathers. The stems may grow to 3 cm in total height. The reproductive bodies are found at the base of the stems and resemble beehives.
