Drewes’ Moss Frog (Arthroleptella drewesii) is known only from the well-protected slopes of the lower Klienrivier Mountain (Fernkloof, Maanschynkop and Vogelgat Nature Reserves) and Babilonstoring, near Hermanus. This tiny frog is found only in fynbos. It breeds in wet mossy areas near densely vegetated streams and hillside seepages. It lays its small eggs in moss where they hatch as froglets, rather than tadpoles. Its call resembles a high-pitched trilling cricket chirp. Hearing them is a special privilege, but do not disturb them – they may soon be the last ones left.
