Down arrow Species Information
Size 1500mm or 59.1" SL. Find near, nearer or same sized spp.
Identification Body has an overall cylindrical shape. Very flattened head. Large long caudal fin. In large specimens the upper jaw surpasses the lower. Overall coloration and color pattern varies greatly over the animal's range, but the fish generall has a broad cream stripe reaching from the gill cover to the caudal peduncle. This light colored stripe may or may not be bordered by darker stripes.
Sexing Unknown. Overall adults sizes for females are reported as larger than those of males.
General Remarks The largest specimen reported from the Amazon was 1.5 meters; Puerto Lopez, Colombia 1.6 meters; Rio Caqueta 97 cm. Considered ''Vulnerable'' to extinction due to overfishing by commercial fisheries. Average adult size captured by commercial fisheries has declined in recent years and now averages under one meter. In Puerto Carreno, on the Rio Orinoco, 5.5 tons of S. planiceps were harvested in 2001. Under Colombian law, specimens under 95 cm may not be retained. This would also make the small specimens imported for the aquarium trade illegal. Sadly, this law is rarely enforced.
