Pseudopimelodidae

The Pseudopimelodidae are a small family (about 40 species) of catfishes known as the bumblebee catfishes or dwarf marbled catfishes. Some of these fish are popular aquarium fish.[1]

Taxonomy

This family was formerly a subfamily of Pimelodidae.[1] Pseudopimelodidae is a monophyletic group.[2] Previously, the superfamily Pseudopimelodoidea was sister to superfamilies Sisoroidea + Loricarioidea.[1] However, some evidence has shown this family, along with Pimelodidae, Heptapteridae, and Conorhynchos, may form a monophyletic assemblage, which contradicts the hypothesis that the former family Pimelodidae that included these families is a polyphyletic group.[3]

Distribution

The Pseudopimelodidae are restricted to fresh water in South America,[1] from the Atrato River in Colombia to Argentina in the Río de la Plata.[2]

Description

These catfishes have wide mouths, small eyes, and short barbels.[4] Their bold markings lead them to be commonly known as bumblebee catfishes or dwarf marbled catfishes.[1] B. acanthochiroides grows to 80.0 cm (31 in) TL.[5] However, most species are smaller; species of the genus Microglanis rarely exceed 70 mm(2.8 in) SL and are never over 80 mm (3.1 in) SL.[4]

gollark: There are *shops* (and groups of shops) which do, but they're not organized like companies.
gollark: They just jump straight to "stock exchanges are cool real life things, how do I make one". And ignore the older, duller, but still important stuff.
gollark: For example, if you buy stock in "GTech Stores", you'd expect to get dividends if I sell anything. But nobody has actually designed a mechanism for company krist accounts, paying dividends automatically, calculating profit, accounting and all that.
gollark: I think a key issue is that there's not really any mechanism for accounting and paying out profit.
