Scott Allen Schaefer (born 1958) is an American ichthyologist working at the American Museum of Natural History as the Dean of Science for Collections, Exhibitions, and the Public Understanding of Science; he serves as the Curator-in-Charge, in the Department of Ichthyology, within the Division of Vertebrate Zoology.^[1]

In addition, he is the Director of the Sackler Institute for Comparative Genomics and a professor, Richard Gilder Graduate School. He is an Adjunct Senior Research Scientist, with The Earth Institute Center for Environmental Sustainability (EICES), The Earth Institute Adjunct Research Scientist, with the Dept. of Ichthyology Columbia Climate School.^[2]

Education

Schaefer attended Ohio State University, where he received a Bachelor of Science degree in 1980. He attended University of South Carolina, where he received his Masters.in Science in 1982. He received his Ph. D. from the University of Chicago, in 1986^[1]

Career

Schaefer studies the systematics, biogeography, and evolutionary morphology of tropical freshwater fishes of Africa and South America. His research seeks to resolve problems in taxonomy, classification, and evolution in those fish groups that dominate the ecology of riverine systems, such as catfishes and characiforms. Fieldwork involves discovery of undescribed fish diversity in poorly known regions, such as the Amazon and Orinoco Rivers of South America. Current projects include systematics and biogeography of Andean freshwater fishes and taxonomic revision of the family Astroblepidae, a group of catfishes that live at high elevations in the Andes of South America. He is also engaged in phylogenetic studies of the trichomycterid catfishes and revisions of African alestid characiform fishes. Recent fieldwork in Peru, Ecuador, and Venezuela has surveyed the diversity of Andean fishes up to 4,500 m (14,760 ft.) elevation and resulted in the addition to the Museum of several new and important collections.^[1]

Legacy

The fish Rhinolekos schaeferi Martins & Langeani, 2011 was named after him.^[3]
Panaque schaeferi Lujan, Hidalgo & Stewart, 2010 as was this fish.^[4]

Loricariidae is the largest family of catfish, with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as "plecos", notably the suckermouth catfish, Hypostomus plecostomus, and are popular as aquarium fish.

Hypostomus is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. H. plecostomus is the popular freshwater aquarium fish formerly known as Plecostomus plecostomus. There is a lot of confusion as to the precise taxonomic structure of the Loricariidae.

Otocinclus is a genus of catfish in the family Loricariidae native to South America, commonly known as "dwarf suckers" or "otos". This genus, like other loricariids, is characterized by rows of armour plating covering the body, as well as the underslung suckermouth. They are generally small in size; O. tapirape is the smallest of the species (2.4 cm), while O. flexilis is the biggest (5.5 cm). These species have adaptations that allow them to breathe air. A duct forms at the junction between the esophagus and the stomach and expands into an enlarged, ring-like diverticulum, characteristic of this genus, which allows air-breathing. Otocinclus are popular aquarium fish, and they are often purchased as algae eaters. It is difficult to breed them in captivity, and only wild caught Otocinclus are available to hobbyists. This genus is widely distributed east of the Andes of South America, throughout the lowlands from northern Venezuela to northern Argentina, but are generally absent from the Amazon and the Orinoco lowlands.

Trichomycteridae is a family of catfishes commonly known as pencil catfishes or parasitic catfishes. This family includes the candiru fish, feared by some people for its alleged habit of entering into the urethra of humans. They are one of the few parasitic chordates. Another species is the life monsefuano which was important to the Moche culture and still an important part of Peruvian cuisine.

Trichomycterus is a genus of fish in the family Trichomycteridae, the largest genus of its family with over 170 species currently described. This genus is native to freshwater habitats in Central and South America. These fish are generally small, usually about 5 to 15 cm (2–6 in) in standard length, although the largest, T. rivulatus, can reach more than twice this size. Species differ from one another primarily in body proportions, fin ray counts and colouration. Despite their relatively small size, some, such as T. punctulatus, support fisheries and are important in the local cuisine.

Loricarioidea is a superfamily of catfishes. It contains the six families Trichomycteridae, Nematogenyiidae, Callichthyidae, Scoloplacidae, Astroblepidae, and Loricariidae. Some schemes also include Amphiliidae. This superfamily, including Amphiliidae, includes about 156 genera and 1,187 species.

Hemiancistrus is a genus of suckermouth armored catfishes. These species are native to South America. The taxonomy of this genus is complex and unclear, and major work has to be done. Many of these fish are popular aquarium fish.

Lithogenes is a genus of South American catfish of the family Loricariidae. It is the only genus within the subfamily Lithogeneinae.

Loricariinae is a subfamily of the family Loricariidae of catfish. This subfamily is divided into two tribes and about 30 genera. They are mainly native to freshwater habitats in South America, but there are also several species in Panama and a single (Fonchiiichthys) in Costa Rica.

The Hypoptopomatinae are a subfamily of catfishes of the family Loricariidae, composed of 17 genera and approximately 80 species. This subfamily represents about one-tenth of all loricariid species.

Nannoptopoma is a small genus of catfishes of the family Loricariidae. This genus includes two species, N. spectabile and N. sternoptychum.

Pseudotothyris is a genus of armored catfishes native to South America.

Harttia is a genus of armored catfishes native to South America.

Parotocinclus is a genus of fish in the family Loricariidae native to South America. This genus is distributed through almost all hydrographic systems in South America from the Guyana Shield drainages and Amazon Shield tributaries to the coastal drainages of eastern and southeastern Brazil, including the rio São Francisco basin. Most species have the caudal peduncle oval in cross section. It has been found that Characidium species may interact with P. maculicauda. The small Characidium will follow grazing P. maculicauda, which release particulate matter dislodged from the catfish's foraging.

Neoplecostomus is a genus of fish in the family Loricariidae native to South America. Neoplecostomus can be distinguished from all other loricariids by a modified shield of small plates on the abdomen with posteriorly directed odontodes; the shield appears to act as a holdfast. The color pattern is generally mottled brown with the abdomen white. The head is long, rounded, and shovel-shaped. The fin spines are weak. They range from about 8 to 11 cm (3.1–4.3 in) SL. The species of Neoplecostomus live in fast-flowing water.

The Sarcoglanidinae are a subfamily of catfishes of the family Trichomycteridae. It includes six genera, Ammoglanis, Malacoglanis, Microcambeva, Sarcoglanis, Stauroglanis, and Stenolicmus.

Rhinolekos is a genus of armored catfishes native to South America. This genus is only known from the Tocantizinho River and Paranaiba River drainage in Goiás, Brazil.

Otothyrinae is a subfamily of South American catfishes order Siluriformes of the family Loricariidae. Alternatively it is treated as a tribe in Hypoptopomatinae.

Panaque schaeferi is a freshwater species of fish from the South American armoured catfishfamily Loricariidae. Panaque schaeferi is widely distributed throughout the upper Amazon in Peruvian and Ecuadorian rivers, and has been observed as far down as Santarém, Brazil. Growing to at least 600mm SL, it is one of the largest, and likely heaviest species of Loricariid. It has been known in the aquarium trade since, at least, 1996 under various names such as 'Titanic pleco' and 'Volkswagen pleco', also L203 and LDA065 under the L-number code. Juveniles are often confused with Panaque bathyphilus and erroneously called L090c.

Loricariichthys edentatus is a species of catfishes found in Entre Rios Province, Argentina. It has no teeth on the premaxilla, a unique feature in the genus Loricariichthys.
