Comparison With The Long-toed Salamander
The Santa Cruz long-toed salamander range is separate from the more common long-toed salamander. Where the range of the long-toed salamander is from Tuolumne County north, the Santa Cruz long-toed salamander is found only near a few isolated ponds in Santa Cruz and Monterey Counties. Like other long-toed salamanders, its belly is sooty to dark brown, and it has tubercles on its feet. The Santa Cruz long-toed salamander has an irregular broken yellow stripe on its back, whereas the common long-toed salamander has a more regular yellow, vertical stripe. Both species have 12 or 13 costal grooves visible from the side. The Santa Cruz long-toed salamander has a measurable degree of mitochondrial DNA genetic distance from the 'coastal' or 'western' subspecies of long-toed salamander. The genetic relationship, however, is still unclear, as more evidence is needed from additional genes and individuals (Thompson and Russell 2005).
In both species, eggs are laid singly near the water surface on rush-like spikes, but sometimes in small clusters at the base of logs or sticking to vegetation in the deeper parts of a pond. Hatching larvae are about 10 mm long, and in their first summer, they grow to 50 to 100 mm, but the Santa Cruz long-toed salamander is generally considered the smaller species. The precise times of migration for both species, to and from the breeding ponds, occur during periods of sustained nighttime rainfall.

Famous quotes containing the words comparison with the, comparison with and/or comparison:
“In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.”
—Henry David Thoreau (1817–1862)
“He was a superior man. He did not value his bodily life in comparison with ideal things. He did not recognize unjust human laws, but resisted them as he was bid. For once we are lifted out of the trivialness and dust of politics into the region of truth and manhood.”
—Henry David Thoreau (1817–1862)
“Clay answered the petition by declaring that while he looked on the institution of slavery as an evil, it was ‘nothing in comparison with the far greater evil which would inevitably flow from a sudden and indiscriminate emancipation.’”
—State of Indiana, U.S. public relief program (1935-1943)
