Description
The twig catfish is a very slender armoured catfish (Loricariidae) from fresh water of the Amazon basin in South America. The species grows to about 10 cm and has a needle-thin body covered with small bony plates and a sucker mouth underneath, with which it stunningly resembles a twig or root fibre.
