- Skeletochronology of the humeri of the three animals examined demonstrated first, that the cross sectional morphology of these branchiate animals consists of a thin bone layer surrounding a large lumen (marrow cavity); a morphology more similar to published photographs of larval animals than adults [ILLUSTRATION FOR FIGURE 4A, C, E OMITTED].
- Size distributions of branchiate salamanders varied seasonally and demonstrate the variability of this subspecies.
It may be that males are slower to metamorphose and therefore overwinter as branchiate animals.
- Paedotypic tiger salamanders are defined as sexually mature animals in branchiate bodies (e.g., Gould, 1977).
Young-of-the-year larvae were present during the summer, but by September these salamanders had either metamorphosed or were continuing to grow as branchiate animals.
