Artenschutz: Metriaclima pyrsonotos wurde durch die Internationale Union für die Erhaltung der Natur (IUZN) in der Roten Liste bedrohter Arten bewertet als (VU) potentiell gefährdet (2006). It is a common species in its native range, but its range is restricted to three isolated areas with only a very few individuals present at Kanchedza Island. This narrow distribution led to its assessment of Vulnerable, but since the species is not targeted by local fishermen (too small and difficult to catch between the rocks), I would suggest that the species should be classified as Least Concern.
