Nadadeira dorsal

Typically a single dorsal fin, often large and sail-like in some genera (e.g., Pterygoplichthys), with a strong spine and soft rays.

Nadadeira caudal

Dicas de identificação

1. 1

   Bony Plates

   The most defining characteristic is the presence of bony plates covering the body, distinguishing them from other catfish families that typically have naked skin or small scales.

2. 2

   Suckermouth

   Their ventral suckermouth is highly specialized for adhering to surfaces and scraping food. The shape and dentition of the mouth can be key for species identification.

3. 3

   Fin Spines

   The presence and structure of spines in the dorsal and pectoral fins are important diagnostic features. Be cautious when handling, as these can be sharp.

4. 4

   Body Shape and Coloration

   While variable, specific patterns, body proportions, and the presence of keels or ridges on the body can help differentiate species within the family.
