This is a list of brown
seaweeds recorded from the
oceans bordering The Cape Peninsula in South Africa from Melkbosstrand on the West Coast to Cape Hangklip on the South Coast.
This list comprises locally used
common names,
scientific names with
author citation and recorded
ranges. Ranges specified may not be the entire known range for the species, but should include the known range within the waters surrounding the Republic of
South Africa.
The marine ecology is unusually varied for an area of this size, as a result of the meeting of two major oceanic water masses near
Cape Point, and the park extends into two coastal marine
bioregions. The ecology of the west or "Atlantic Seaboard" side of the Cape Peninsula is noticeably different in character and
biodiversity to that of the east, or "
False Bay" side. Both sides are classified as temperate waters, but there is a significant difference in average temperature, with the Atlantic side being noticeably colder on average.[1]
List ordering and
taxonomy complies where possible with the current usage in
Algaebase, and may differ from the cited source, as listed citations are primarily for range or existence of records for the region.
Sub-taxa within any given
taxon are arranged alphabetically as a general rule.
Details of each species may be available through the relevant internal links.
Synonyms may be listed where useful.
