Pterygoplichthys anisitsi[1][2] also known as the Paraná sailfin catfish, southern sailfin catfish, or snow-king plecostomus, is a species of catfish in the family Loricariidae.[3] Its natural range is the middle Paraná and Uruguay River basins of south-central South America,[4] but it has been introduced to North America and South Asia, probably via the pet trade.[5][6] As in other loriacartii catfishes, Pterygoplichthys anisitsi has a ventral mouth modified into a sucking disk and a body covered in bony plates.[4] This species typically has a dark and white spotted body pattern, although some individuals are very dark with few spots.[5]

Gas exchange and respiration[]

Pterygoplichthys anisitsi is capable of breathing both air and water. During nighttime or when the fish experiences a low-oxygen environment, it will swim to the surface to gulp in air.[7] When breathing air, they use their stomach for the diffusion of oxygen into the blood.[8]
