Tiger Shovelnose Catfish

The tiger shovelnose catfish is a large predatory species in the family Pimelodidae, native to the Amazon and Orinoco river basins of South America. It is named for its distinctive flattened, shovel-shaped snout and bold black striping across a pale body, patterning reminiscent of a tiger. This species inhabits the main channels and deep pools of major river systems, where it functions as an important predator of smaller fish. It can grow to over a meter in length and is among the more recognizable large catfish species found throughout tropical South American rivers due to its striking pattern and elongated head shape.

Key identification features:

• Elongated body with a distinctly flattened, shovel-shaped snout
• Cream to tan base coloration overlaid with bold, irregular black vertical bars and spots
• Long barbels extending from the mouth
• Deeply forked caudal fin
• Broad, low, flattened head shape unlike most other catfish
• Adults typically reach 70 cm to over 1 m Its uniquely shovel-shaped head combined with bold tiger-like striping make it easily distinguishable from other large South American catfish species.

Tiger shovelnose catfish inhabit the main channels, deep pools, and larger tributaries of the Amazon and Orinoco river basins across Brazil, Peru, Colombia, Venezuela, Bolivia, and Ecuador. They favor warm freshwater generally between 24-28°C with moderate to strong current and access to deep refuge areas. This species is typically associated with river confluences, deep bends, and areas of structural complexity that concentrate prey. Its broad range across major South American river systems reflects strong adaptability to varied lowland tropical river conditions.

This species is a nocturnal ambush predator, using its flattened snout and sensory barbels to detect and capture fish and other prey in low-visibility water. Tiger shovelnose catfish are largely solitary, holding position near cover or structure and striking at passing prey rather than actively chasing over long distances. They undertake seasonal movements linked to river flow and flood-pulse dynamics, migrating to access feeding or spawning habitat as water levels change. As a significant predator within Amazon and Orinoco river systems, it plays an important role in structuring fish communities, and its populations are influenced by river connectivity and habitat quality across its range.
