Megalechis thoracata (black marble hoplo[1]) is a species of catfish of the family Callichthyidae. M. thoracata is found east of the Andes in the Amazon, Orinoco, and upper Paraguay River basins, as well as in the coastal rivers of the Guianas and northern Brazil. Recent introductions were recorded in the upper Paraná River drainage.[2]

Ecology

M. thoracata has been observed to produce sounds during territorial behavior in males at their nest sites and especially during spawning, and during aggressive behavior in both sexes. M. thoracata males aggressively defend territories against intruders.[3]
