Pterapogon kauderni

Overview

NOAA describes a tasseled first dorsal fin, elongated second dorsal and anal rays, and a deeply forked tail. Dark and light bars cross a silvery body dotted with whitish spots. The spot pattern varies among individuals. Its native shallow, calm reef and seagrass habitat is restricted to the Banggai Archipelago.

Vagelli and Volpedo’s 2004 reproductive study compared laboratory-bred and wild-collected eggs and embryos. Wild males brooded clutches with variation in egg size both within and among clutches. Mean egg size was not correlated with the size of the brooding male.

NOAA reports that males incubate eggs orally and release fully formed juveniles. Individuals introduced outside the native range must be distinguished from endemic populations. The study’s reproductive measurements do not identify the sex of an imagined fish from its dot pattern.
