manillensis is a species of marine catfish endemic
to the island of Luzon, Philippines. It is found in
the area around Manila, Bataan, Laguna, Cavite, and
Rizal; including the Pasig River and Laguna de Bay.
It inhabits marine, brackish, freshwater, and benthopelagic
habitats. Reproduction: Arius
manillensis are mouthbrooders. The males of the
species incubate the eggs within their mouths for
six to eight weeks and provide shelter for the young
once they hatch. A single instance of a female carrying
eggs in her mouth has also been reported. Upon hatching,
the young forage for plankton in short bursts but
will quickly return to the safety of the mouth of
the adult if alarmed. They eventually become independent
once they reach a size of 30 to 44 mm (1.2 to 1.7
in). During the entire period, the adults do not eat
and their stomachs shrink dramatically. Remarks:
Was first described by the French zoologist Achille
