Parechinus angulosus
Cape urchin
Importance:
Parechinus angulosus, the Cape urchin, plays a critical ecological role along South Africa's rocky shores, influencing algal distribution and maintaining community balance through its grazing activities. It is a key prey species for a variety of predators, including the endangered West Coast rock lobster (Jasus lalandii), thus supporting broader food web dynamics. While not a major fishery species itself, it contributes to ecosystem services that sustain economically important coastal fisheries.
