Twig Catfish
Farlowella acus
Twig catfish inhabit slow-moving, clear rivers and flooded margins in northern South America, where submerged wood and vegetation provide cover. They cling to branches and stems with a suction-cup mouth, grazing algae and biofilm from hard surfaces. Their extremely slender, stick-like body and mottled brown pattern make them remarkably difficult to spot among twigs. Males guard egg clusters laid on exposed surfaces until they hatch.
