Pseudoplatystoma punctifer or spotted tiger shovelnose catfish[2] is a species of long-whiskered catfish native to the Amazon basin, in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela.[3] It is a commercially farmed species, and it is difficult to harvest as it appears to be highly selective with its diet[4] and exhibits cannibalistic behaviors. Other behaviors and developmental patterns vary based on both diet as well as parental behaviors that influence the organisms development from the Larval stage.[5]

This species reaches a maximum of 140 cm (55 in) in total length; 37–40 vertebrae.[3]
