Carachama Mama
The local word for pleco combined with "Mama" is the common name for these spp throughout the Amazon. The idea being that, since they are the biggest sp found, all other plecos (
Hypostomus, etc) are their babies.
Western science groups, distinguishes, and defines spp by their believed evolutionary history, which defines how we see and interpret the world around us. Other peoples throughout the world have very different ways of arranging the natural world with size often an important factor. The Yanomami place the freshwater dolphin, red tailed catfish, humans, jaguar and tapir in the same "family" as all are big. A red tail cat thus, in the traditional view, is more closely related to humans and jaguars than it is to say a pleco or doradid.
A herpetologist friend of mine did an ethno-taxonomic study with the Yanomami of turtles. There are 30 something turtle spp found where the Yanomami live. Guess what? They have two words for turtle, one translates as "big turtle" and another as "small turtle."
