An Investigation into Tetrodotoxin (TTX) Levels Associated with the Red Dorsal Spots in Eastern Newt (<i>Notophthalmus viridescens</i>) Efts and Adults

<div>Regression of the total number of red dorsal spots and the predicted whole body TTX (mg) of Eastern newt (<i>Notophthalmus viridescens</i>) efts. Efts with more red dorsal spots possess greater concentrations of TTX in the skin (F = 17.5, R<sup>2</sup> = 0.57, P = 0.001). The whole body TTX estimate for each eft was the average of the paired estimates from the punch containing and lacking a red dorsal spot.</div>
