They are also known as "catfish" because of the presence of several chins, sometimes very long. Indeed, like cats, chins serve as sensitive organs to detect food in murky waters of poor visibility.
They are almost all freshwater fish. They have bare skin devoid of scales in almost all species. However, others have the body covered with shields.
Among marine silurids there are species that incubate large eggs in the oral cavity.
They are carnivores. Some use the spines of the pectoral and first dorsal fins as a defensive organ, sometimes a venom secretor.
Some typical species:
European catfish or glamo (3 m).
Misgurno
Cobítidos
They are small fish that live on the bottom of rivers and ponds.
They have 6 to 12 chins around the mouth.
They feed on small organisms, larvae, etc.
When the water does not have enough oxygen, they rise to the surface and swallow air that they then expel through the anus.
They can remain dormant in the mud for up to a year.
