Body shape (shape guide): elongated.
The spines are said to be poisonous (Ref. 4537). Found in pools and slow flowing reaches of perennial and seasonal rivers; prefers riverine habitats to floodplains; shelters in holes or crevices or on the underside of logs, frequently in an upside-down position (Ref. 52193). Active at night, feeds on detritus and plant matter such as seeds as well as small invertebrates like insects and snails, and will scavenge readily (Ref. 52193). Breeds in summer during rainy periods (Ref. 7248, 52193). Oviparous (Ref. 205).
