Coelacanth off Pumula on the KwaZulu-Natal South Coast, South Africa, on 22 November 2019 Kelps Laminaria pallida (top) and Ecklonia maxima (below). The Marine biodiversity of South Africa is the variety of living organisms that live in the seas off the coast of South Africa.
The lower body temperature of poikilotherms is accompanied by a seasonal nature of the immune response in these hosts resulting in a quantitatively reduced pathogenesis. Hosts that did succumb to the infection would most likely die in water where eggs could be released by predation, scavengers, or decomposition and develop successfully.
Carpet flatworms may grow to 8 cm in total length. They have pale bodies with pinkish frilled margins. The upper surface of the animal is covered with short finger-like papillae (protrusions) in pinks, caramels and browns. There is a smale pale protruding fold at the head. [2]
The Platyhelminthes have very few synapomorphies - distinguishing features that all Platyhelminthes (but no other animals) exhibit. This makes it difficult to work out their relationships with other groups of animals, as well as the relationships between different groups that are described as members of the Platyhelminthes.
South Africa has a wide range of marine diversity with coastline in three oceans, two major current systems, major ocean frontal systems and benthic topography extending to a maximum depth of 5 700 m. There are 179 defined marine ecosystem types, 150 of them around South Africa and 29 around the sub-Antarctic territory of the Prince Edward Islands.
Topography of South Africa. South Africa is located in subtropical southern Africa, lying between 22°S and 35°S.It is bordered by Namibia, Botswana and Zimbabwe to the north, by Mozambique and Eswatini (Swaziland) to the northeast, by the Indian Ocean to the east and south, and the Atlantic Ocean to the west, the coastline extending for more than 2,500 km (1,600 mi).
Platyhelminthes (from the Greek πλατύ, platy, meaning "flat" and ἕλμινς (root: ἑλμινθ-), helminth-, meaning "worm") is a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms.
It was thus found that there was a positive correlation between snail mortality and temperature. This seasonal difference can be explained by different foraging behaviors, different microclimatic conditions, and different densities. [10] A rare observation of Platydemus manokwari scavenging on a dead human body was reported in 2024 in Australia ...
