Glass Frog
Luz Burgos
Name
 The
Glass Frog’s scientific name is
hyalinobatrachium pellucidum.
 The
Glass Frog had gotten its name
because of its translucent skin on the
underside of its body that lets you see
their organs.
 Glass
Frogs are amphibians.
Features



Transparent skin: the glass frog has
transparent skin on its underside (some
species have on the top), which makes it
hard for their predators to see them.
Glass Frogs are very small, their average
size are 1.4 to 3 centimeters long.
Through its transparent skin you can see
the liver, heart, digestive tract and
sometimes its lung.
Features
 Unlike
other frogs, Glass Frog’s have their
eyes facing the front.
 Most
of the frogs are different shades of g,
and some are brown.
 The
Glass Frog called, ocelli has tiny spots
covering its body.
Location

Glass frogs can be found in the rainforests
of Central and South America
Diet
 Small
Glass Frog’s will typically eat small
insects.
 Giant
Glass Frogs from the pacific, will
usually eat small fish or other frogs.
Reproduction
 Almost
all glass frogs are arboreal.
 Breeding happens closer to streams
and rivers, anywhere from 10 to 20 feet
in the air.
 Parents keep an eye on eggs because
of maggots and larvae of wasps.
 The Glass Frog breeds its eggs on a leaf
up in the air, so that they can fall
directly into the stream.
Tadpoles
 When
tadpoles fall into the stream, they
have a lack of pigment, small eyes, and a
strong swimming tail.
Tadpoles
 Next,
before the tadpoles turn into tiny
little frogs their eyes begin to get larger,
their tiny hind legs begin to grow and their
digestive tracks change, so that they can
eat animal prey.
Extinction and Species
 There
are over 134 species of glass frogs
with 60 of the species threatened.
 If
Glass Frogs where to be extinct, then
there would be no bio indicator for flora
and fauna.

Why They are Endangered
 Glass
Frogs are endangered because of
the fungus that is taking over their homes
 The
 The
fungus is called Chytridiomycosis.
fungus causes the amphibians skin to
get infected. This change can be deadly
because they observe water through their
skin instead of their mouths.

Facts

Glass Frogs are nocturnal

They are arboreal

In certain species, the male guards the eggs
until they hatch

They have to hide during strong rains due to
their fragile bodies

Adults are more active at night and during
light precipitation
More Facts

They help control insect population

Freshwater creature

Fewer than 5,000 glass frogs excist since of
2004

After breeding season most lass frogs go back
up to the canopy

Great use of bioindication
Nocturnal
 During
the night, Glass Frogs are very
active and are hunting for food.
 From
very late at night to very early
mornings they spend their time breeding

Glass Frog Discovery
 Glass
Frogs have recently been discover
in the mountains of Ecuador and
Columbia
