Jefferson or spotted salamander larva just out of the jelly... we are watching them grow. Definitely <i>Ambystoma maculatum</i> - if the time stamp is correct (May 12) that's eliminates <i>A. jeffersonianum</i>. By the time <i>A. maculatum</i> is hatching, <i>A. jeffsonianum</i> are large enough to be feeding on the newly hatching <i>A. maculatum</i>
