In this issue:
Duane Patricio, Cheryl Lemalu, and
Robert Diaz with a captured coqui
frog from Walmart
growing on the intake side of the
reservoir has been removed.
This has resulted in a much drier
and open area making it inhospitable for the frogs.

Tidbit
The frog does not seem to
see or, at any rate, is not
concerned with the detail
of stationary parts of the
world around him. He will
starve to death surrounded
by food if it is not moving.
His choice of food is determined only by size and
movement.

Frog eyes
A frog hunts on land by
vision. He escapes enemies
mainly by seeing them. His
eyes do not move, as do
ours, to follow prey, attend
suspicious events, or search
for things of interest.
Frogs have fairly good eye-
sight, which helps them in
capturing food and avoiding
enemies. A frog's eyes bulge
out, enabling the animal to
see in almost all directions.
Frogs can close their eyes
by pulling the eyeballs deeper
into their sockets. This ac-
tion closes the upper and
lower eyelids.
Most species also have a
thin, partly clear inner eyelid attached to the bottom
lid. This inner eyelid, called
the nictitating membrane,
can be moved upward when
a frog's eyes are open. It
protects the eyes without
completely cutting off vision.
Most frogs have a disk of
skin behind each eye. Each
disk is called a tympanum,
or eardrum. Sound waves
cause the eardrums to vibrate. The vibrations travel
to the inner ear, which is
connected by nerves to the
hearing centers of the brain.

more information.

Do frogs have teeth?
Actually, yes! But not
like in this silly picture!
Most frogs do in fact
have teeth of a sort.
They have a ridge of
very small cone teeth
around the upper edge
of the jaw. These are
called Maxillary
Teeth.
Frogs often also have
what are called Vomerine Teeth on the roof
of their mouth.
They don't have anything that could be called
teeth on their lower jaw,
so they usually swallow
their food whole. The
so-called "teeth" are
mainly used to hold the
prey and keep it in place
till they can get a good
grip on it and squash
their eyeballs down to
swallow their meal.
