Scale performance and composition in a small Amazonian armored catfish, Corydoras trilineatus
Acta Biomaterialia, 2021 The cory catfishes (Callichthyidae) are small, South American armored catfishes with a series of dermal scutes that run the length of the fish from posterior to the parieto-supraoccipital down to the caudal peduncle. In this study, we explore the anatomy and functional performance of the armored scutes in the three-striped cory catfish, Corydoras ...

Histopathological evaluation of seven Amazon species of freshwater ornamental armored catfish [PDF]
Acta Scientiarum: Biological Sciences, 2014 Fish commonly known as acaris or plecos are freshwater armored catfish economically important as a food resource and as ornamental fish. Most of these species are captured in the Amazon region. However, despite its economic importance, there is a lack of

Epithelial gill cells in the armored catfish, Hypostomus cf. plecostomus (Loricariidae) [PDF]
Revista Brasileira De Biologia, 2001 Epithelial gill cell morphology and distribution were investigated in the armored catfish, Hypostomus cf. plecostomus, which lives in soft ion-poor Brazilian freshwaters. Pavement cells are the most abundant type of cell on both filament and lamellar epithelia and there are a great number of mucous and chloride cells between them.

Movement and mortality of invasive suckermouth armored catfish during a spearfishing control experiment. [PDF]
Biol Invasions, 2022 Control of non-native, invasive species in groundwater-dependent ecosystems that are also inhabited by regionally endemic or at-risk species represents a key challenge in aquatic invasive species management. Non-native suckermouth armored catfish (SAC; family Loricariidae) have invaded freshwater ecosystems on a global scale, including the groundwater ...

Hemiancistrus guahiborum, a new suckermouth armored catfish from Southern Venezuela (Siluriformes: Loricariidae) [PDF]
Neotropical Ichthyology, 2005 Hemiancistrus guahiborum, new species, is described from the Orinoco River drainage of Venezuela. Hemiancistrus guahiborum can be separated from all other Hemiancistrus and all Peckoltia except P. braueri and P.

Whole genome assembly of the armored loricariid catfish Ancistrus triradiatus highlights herbivory signatures. [PDF]
Mol Genet Genomics, 2022 AbstractThe catfishAncistrus triradiatusbelongs to the species-rich family Loricariidae. Loricariids display remarkable traits such as herbivory, a benthic lifestyle, the absence of scales but the presence of dermal bony plates. They are exported as ornamental fish worldwide, with escaped fishes becoming a threat locally.

An evolutionarily conserved odontode gene regulatory network underlies head armor formation in suckermouth armored catfish [PDF]
, 2021 ABSTRACTOdontodes, i.e., teeth and tooth-like structures, consist of a pulp cavity and dentine covered by a mineralized cap. These structures first appeared on the outer surface of vertebrate ancestors and were repeatedly lost and gained across vertebrate clades; yet, the underlying genetic mechanisms and trajectories of this recurrent evolution remain

Independent evolution of satellite DNA sequences in homologous sex chromosomes of Neotropical armored catfish (Harttia). [PDF]
Commun BiolAbstract The Neotropical armored catfish Harttia is a valuable model for studying sex chromosome evolution, featuring two independently evolved male-heterogametic systems. This study examined satellitomes—sets of satellite DNAs—from four Amazonian species: H. duriventris (X1X2Y), H. rondoni (XY), H. punctata (X1X2Y), and H. villasboas (X1X2Y).

Phylogenetic analysis of microbial communities in different regions of the gastrointestinal tract in Panaque nigrolineatus, a wood-eating fish [PDF]
, 2012 The Neotropical detritivorous catfish Panaque nigrolineatus imbibes large quantities of wood as part of its diet. Due to the interest in cellulose, hemi-cellulose and lignin degradation pathways, this organism provides an interesting model system for the
