Chaetostoma Species Guide

Chaetostoma species are a type of catfish found in the freshwaters of South America, specifically in the Amazon and Orinoco river basins.

These fish are relatively small, typically growing up to 2-3 inches in length.

Chaetostoma species are nocturnal, meaning they are most active at night, and have poor eyesight, relying on their sense of smell and lateral lines to navigate their surroundings.

They are social animals and are often found in small groups in the wild.

Chaetostoma species are quite diverse, with over 40 recognized species in this genus.

The most recent species to be discovered is the Chaetostoma orientale, described as recently as 2022.

Some of the earliest species to be recognized include Chaetostoma fischeri and Chaetostoma guairense, both described by Steindachner in the 19th century.

The genus Chaetostoma also includes species like Chaetostoma daidalmatos and Chaetostoma changae, both described by Salcedo in 2006.
