The Forgotten Survivors |
| |
Well
they're not really forgotten, we just didn't have enough time to make
shows about ALL of our Desert Survivors. So here are a few that haven't
yet landed those big time movie roles. |

The
amargosa toad, Bufo nelsoni, is one of Nevada's endemic species,
or perhaps subspecies. Scientists still haven't decided if Bufo
nelsoni is a species of its own or a subspecies of Bufo
boreas, the western toad. Either way, these cute little critters
are found only one place in the state of Nevada. If you believe
they Bufo nelsoni to be a distinct species, then they are
only found in one place in the world. The Amargosa Valley north
of Pahrump is the only known habitat for this endangered animal. |

Dragon
flies, suborder Anisoptera, are one of our aggressive little pond
goers. Their larvae, or babies, develop in the water and are ferocious
predators. So even as adults, they don't get too far from standing
water! The come in all sorts of beautiful colors and a wide variety
of sizes. |

|
| |
 |
Though
they look like miniature horseshoe crabs, these little desert pond
critters are not crabs at all! The tadpole shrimp, or Triops,
is a crustacean that finds its home in desert ponds called tinajas.
They are ferocious predators
and tend to chase all the other pond inhabitants. When their
ponds dry up, they survive as desiccation tolerant
cysts. |

Caddis
flies are shy little Desert Survivors. The day they hatch in the
water, they hurry about and gather small pieces of sand and detritus (leaves
and other organic material). They glue all these little pieces
together with their sticky saliva (spit) and make themselves a
little case. They live inside their case and as they grow, they
add more materials to the outer brim. Eventually, they will pupate and metamorphose into
adult caddis flies that look very much like moths. |

These
enormous moths are often mistaken for humming birds in the early
evening sky. They dart about and may even dive-bomb you if sit
out on your porch just after the sun sets in the summer time. They
are the largest flying insects in the Mojave Desert, with a wingspan
anywhere from 5cm to 20cm (2 to 8 inches)! |

The
black toad, Bufo exsul, is endemic to
the Mojave and
happens to be endangered as
well. They are naturally found in only one location: Deep Springs
near Bishop, California. Though they have been found in Death Valley,
it is thought that they were introduced. |

Tree
frogs in the Mojave? The Pseudacris regilla, or pacific
chorus tree frog (once known as Hyla regilla), is found
in all sorts of varieties all over southern California, northern
Arizona, and southern Nevada. In southern Nevada, they are most
common in mountain streams, like First Creek and Pine Creek in
Red Rock Canyon. |
|
| |
|
| |
 |
Many
people mistake them for large chipmunks (but notice they do not
dorn lines on their fuzzy faces), but they are actually ground
squirrels with little wispy tails. One of the world's finest hibernators,
the golden-mantled ground squirrel is found all over the western
United States. In the Mojave they can be found in mountian regions
like the Spring Range, which includes the familiar Mt. Charleston. |

The
elusive desert chicken is a rare sight; there is only one in the
entire world! She only comes out on February 30th. If she sees
her shadow she goes back into her shrubbery and does not emerge
again until the next February 30th. |
