Phallostethid fishes are small and very unique fishes that the males have their
penis or priapium under their chin or chest. In this study, the diversity and
distribution of Phallostethid fishes in Peninsular Malaysia was investigated and
the environmental biology and ecology of selected species, Phenacostethus
smithi, at Sungai Pur, Kuala Berang, Terengganu was determined. Results of
this study showed that Phallostethid fishes were found occur in a few states in
Peninsular Malaysia. Phenacostethus smithi at Sg. Pur did not show dimorphic
in size between male and female. Both adults and juverniles were collected
during sampling period suggested that Phenacostethus smithi breed all-year
round. Phenacostethus smithi can inhabit different type of habitats for example
freshwater streams and brackish creeks. Further studies should be carried out
to acquire more information about Phallostethid fishes about their distribution,
biology and ecology in Peninsular Malaysia.
