Spadefoot Toads are one of the strange things of the universe.
They are true ephemera, appearing as if by magic after sudden thunderstorms, and
staying above ground only a few days each year, just long enough to mate and lay
eggs. With shining eyes more beautiful than the finest gold foil, Spadefoots are
humble and harmless creatures, unless you are a very small
ground-dweller. Spadefoots breed in desert streams and pools that usually dry up
within a few short weeks. Their eggs hatch with astonishing rapidity--within a
few hours. The fast-growing tadpoles are spooky. In each batch, some tadpoles
are vegetarians, grazing upon algae and water plants. Others are carnivorous,
and feed upon water insects, tiny fish--and especially their own brothers and
sisters! The carnivorous tadpoles grow faster than the vegetarian tadpoles. If
the water is drying up, or is so temporary that algae have not had a chance to
grow, then the carnivorous tadpoles can live upon their own kind until they turn
into little toadlets in six to twelve weeks, and hop away. This bizarre
lifestyle works well in the chancy dry environments where Spadefoots live. When
the toadlets emerge from the water, they hop off to a place where they can dig
in soft earth, and bury themselves until a thunderstorm signals them to come out
for mating, just as their parents did. There are several kinds of Spadefoot
Toads in North America, and like many amphibians, they are in trouble, so foster
them if you can. Spadefoots are found in the western Great Plains and in the
West. This little fellow posing for Uncialle's camera is the Intermountain
Spadefoot, Spea intermontana, the one that lives in Uncialle's gulch.
The arrow points to the hardened hind foot "spade" that the toad
uses to help dig itself into hibernation/aestivation. Now, in early June, two of
Uncialle's ponds still have Spadefoots calling at night, each toadly male
singing hopefully for a mate to join him. "Rrrraaack! Rrrraaack!" they sing into
the cool night of the gulch. Spady tadpoles swim languidly about in the water,
their little brown eyes questing here and there for a morsel of food. Uncialle
stocks the Spadefoot pools with large snails, and the carnivorous tadpoles eat
far more snail eggs than siblings. Do the tadpoles dream of the day when their
eyes will turn to gold? Do the adults, snug in their earthen chambers, dream of
the thunder that will awaken them? Truly, there is no magic like the real magic
of the earth.
Surely there is still a place in the world for the
creature with the golden eyes.
