For this study, we thoroughly surveyed the island of Bangkulu
(Fig. 1). While the eastern shore of the island supports a continuous
habitat suitable for P. kauderni (green outline, Fig. 1), the northwestern
shore of the island is devoid of the species (red outline, Fig. 1), mostly
due to the presence of steep slopes and lack of coral reefs and other
suitable shallow habitat.
