Whale sharks have been sighted in many places in Indonesia, including Probolinggo, Gorontalo, Teluk Saleh, Kaimana, and Teluk Cendrawasih. These sightings mostly occurred close to floating lift nets called bagan, where the whale sharks can feed on anchovies and rebon shrimp (Acetes sp.) which are both among their preferred prey. However, at Botubarani in Tomini Bay the whale sharks do not aggregate around lift nets; instead, they appear at the sea surface in their search for seasonal schools of migratory fish larvae known locally as nike. These nike are the larvae of several species of goby (thought to be Awaous sp.) which spend most of their lives in freshwater but have a larval stage in estuarine or coastal seawater. In addition, some researchers have suggested that chlorophyll concentrations in the sea surface layer can be used to indicate the spatial distribution and help predict the presence of whale sharks Taken @Makassar, Gorontalo, South Sulawesi
