Pseudoplatystoma fasciatum or Barred Sorubim is a species of South American Catfish native to Paraguay, the Rio Lebrijo in Venezuela, and the Rio Negro in Peru. The nocturnal predator feeds mainly on other fish and crabs. Females reach a more notable size. They become sexually mature at 56 cm, males at 45 cm. Fecundity is estimated at 8 million eggs per kg.
This catfish has an elongated body and a long snout. Its mouth is large and looks like a duck-bill. Three pair of long barbels extend from it. This fish is slender and its body coloring ranges greatly depending on the individuals habitat and age. Its coloration usually ranges between silver and brown while its belly is usually white to silver. Black spots and stripes are arranged in irregular patterns on the fish body and fins. The eyes are relatively small. 

体长100cm左右,体呈优雅的流线形,体上有十几条横纹,头稍呈扁平,吻大而扁平似圆锹,什么东西都吃,是标准的大食客。经常以迅雷不及掩耳的速度在水中遨游。因地域的不同或变换,鱼身的斑纹亦会为之改变,并且会随着蜕皮而成长,脱下的皮也会被其吃掉,为其最大的特征。因身上的花纹不一,也有别的种类如:圆点鸭嘴,珍珠虎皮鸭嘴等.是大型鲶鱼中最受喜爱的鱼种之一。
