Weight-Length and Length-Length Relationships of the Endangered Zebra Pleco Hypancistrus zebra (Siluriformes, Loricariidae) from the Xingu River, Amazon, Brazil

Figure 10

Length-to-length ratio (LLR) of males of Hypancistrus zebra based on the equation y = (LOG (SL)) = LOG (a) + (b) x = (LOG (TL)), where (a) is the intercept, (b) is the angular coefficient, and R² is coefficient of determination. (SL) is the LOG of standard length in cm, and (TL) is the LOG of total length in cm.
