Armored Catfish are relatively unique to South American neotropical lowland streams. They play a key role in the maintenance of the stream ecosystem by recycling sediment and algae. Plenty of research has been done, specifically regarding Costa Rican armored catfish, making it important to the scientific research currently underway in Costa Rica.
