Family Sisoridae
Asia. Characterised by small, skin-covered eyes, very thick-based maxillary barbels and a well developed adipose fin, these catfishes have the ventral parts flattened, often with folds of skin. This helps the fish cling onto flat surfaces in the torrential waters of fast flowing streams where they frequent.

Wrinkle-bellied Catfish
Glyptothorax major
Ikan Depu,

Primarily freshwater fish; 6.5 cm; oviparous; omnivorous; solitary; benthic. Indigenous, endangered. Forest streams.

Although it is found in fairly small, rather quiet streams, it is adapted to hold onto plants or rocks in the event of storms, which can quickly turn its home into a violent torrent. In Singapore, it is very rare and not known outside the catchment area.
