What physical feature is the Wels Catfish body structure optimized for?

Answer

Slow, powerful movements along the riverbed

The morphology of the Wels Catfish reflects its specialization as a benthic (bottom-dwelling) predator. Its substantial bulk, often exceeding two meters in length and 90 kilograms in weight, is supported by a body shape fundamentally different from fast-swimming fish. Unlike many active teleosts, *S. glanis* possesses long, tapering fins combined with a body form that is perfectly optimized for executing slow, yet powerful, movements across the deep lake floor or riverbed. This physical design is an evolutionary outcome shaped by the need to capture large food items opportunistically from the bottom rather than engaging in sustained pursuit through the water column.
