features

They are scaly, their bodies are elongated or squat. Their mouth is often slightly below and surrounded by three to four pairs of barbels . The pectoral and dorsal fins are supported by strong, barbed spines, from which the name "Stachelwelse" is based. The short dorsal fin has six to seven, more rarely up to 20 soft rays . The anal fin is short, the caudal fin is usually forked. The pelvic fins have 6 fin rays. All spiny catfish have an adipose fin that is often very large. In many species the eyes are overgrown with skin. The anus and genital opening are not close to each other, the posterior process of the shoulder girdle is well developed. The fish are four centimeters to 1.65 meters long, depending on the species. Most are active at night or at dusk.

Genera and species

The genera Nanobagrus and Rita were placed in the Ritidae family in 2016 . Since then, the spiny catfish have only included the species of the former subfamily Bagrinae.
