Native to South and Central America, many of the 700 species
of suckermouth armored catfishes (Loricariidae, Siluriformes) are popular with aquarium hobbyists as algae-controlling ornamental fishes and are therefore bred, shipped and sold around the world. They are characterized by bony plates covering the body, a pair of subterminal barbels, sucking lips, usually a spine in front of the adipose fin, and a flat-bottom body shape (Page and Burr, 1991), and are naturally occurring in a variety of freshwater habitats from sea level to 3000 m, often surviving in conditions that exclude other fishes. Members
of the genus Pterygoplichthys differ from most other
loricariids by having a large dorsal fin with 10 or more dorsal fin rays, which gives them their common name �sailfin catfish (Nico and Martin, 2001; Nelson et al., 2004; Page and Robins, 2006). Three species of Pterygoplichthys (Pterygoplichthys multiradiatus, Pterygoplichthys pardalis, and Pterygoplichthys disjunctivus) are closely related in that they lack an elevated supraoccipital process and have the supraoccipital bone posteriorly bordered by three scutes. Among these three species only P. multiradiatus (Hancock, 1898) has a pattern of uncoalesced dark spots on a light background (Page and Robins, 2006)read more

TL;DR: In this article, the authors investigate the distribution of brGDGTs in 470 samples from 96 peatlands around the world with a broad mean annual air temperature (−8 to 27 °C) and pH (3-8) range and present the first peat-specific brGGT-based temperature and pH calibrations.

Identification of exotic sailfin catfish species (Pterygoplichthys, Loricariidae) in Taiwan based on morphology and mtDNA sequences.
TL;DR: The results indicated that the fish occurring in Taiwanese rivers should be identified as P. pardalis and P. disjunctivus, and put forth 2 hypotheses and 1 speculation to explain the current situation.

The Global Invasion of the Suckermouth Armored Catfish Genus Pterygoplichthys (Siluriformes: Loricariidae): Annotated List of Species, Distributional Summary, and Assessment of Impacts.
TL;DR: An annotated checklist of species for this taxonomically confusing genus Pterygoplichthys is provided and the overall socioeconomic and environmental impact of the genus on a global scale is assessed using the Generic Impact Scoring System (GISS).

Discovery of South American suckermouth armored catfishes (Loricariidae, Pterygoplichthys spp.) in the Santa Fe River drainage, Suwannee River basin, USA
TL;DR: The first confirmed records of Pterygoplichthys gibbiceps in the Suwannee River basin represent the first documented record of an adult or near adult of this species in open waters of North America and eradication might be possible during cold periods when catfish congregate in spring habitats.

Comparisons of isotopic niche widths of some invasive and indigenous fauna in a South African river
TL;DR: Overall, although the invasive T. granifera and P. disjunctivus were not in direct competition for dietary resources with native species in the Nseleni River system, their spread in isotopic space suggests they are likely to restrict energy available to higher consumers in the food web.
