Program Overview
Tropical rainforests are the most biologically diverse terrestrial ecosystems on our
planet. More species of trees, plants, insects, reptiles, birds and other animals are
found in tropical rainforests than any other place except, perhaps, tropical coral reefs.
In this program, you will meet a variety of animals that live in tropical rainforests and
learn how each animal is adapted to this habitat. We will also discover how the
rainforest is divided into layers and learn how animals survive in these different
layers. We will learn why tropical rainforests are important for animals and for all of
us.
Below is a list of possible animals your students might meet during this program:
1. Snakes(1-2)
• Boa Constrictor
• Honduran Milk Snake
2. Amphibians(0-1)
• Australian Tree Frog
3.

•
•
Lizards(2-4)
Green Iguana
Tegu
Prehensile Tailed Skink
Crested Gecko
4. Turtles/Tortoises(1)
• Softshell Turtle
• Snapping Turtle
Depending on the duration of your program, students will meet 5 animals (30 minute
show) or
7 animals (45 minute show).

What is a Tropical Rainforest?
Tropical rainforests are located near the equator, so they stay hot all year –
there is no “winter” as temperate regions experience.
Rainforests receive 85 inches or more of rain each year, but there may be a “dry” and
“wet” season. High humidity, constant warmth, lots of sunshine, and loads of rain
promote plant growth year round. Trees become enormous!
Scientists divide the rainforest into different levels:

The emergent layer is where the tallest trees (over 100 feet tall) break free of the
canopy. In these towering tree tops live animals such as the majestic harpy eagle
and the beautiful bird of paradise
The canopy is where most of the action in the rainforest is happening. This is
where all the tree branches have grown together to form a habitat for animals
such as: monkeys, macaws, iguanas, treefrogs, prehensile tail skinks, carpet
pythons, and other interesting animals.
The under story is where all of the little trees are trying to grow and break
through the branches above them. These trees may be very old even though
they are small. You can find baby boa constrictors, geckos, and insects here.
The forest floor is at ground level. This is a very dark, twilight zone area – even in
the day - because the branches and leaves above block out most of the light.
In a mature rainforest, the forest floor is open and easy to walk through since plants
have a hard time growing in such low light. The soil is very thin, but covered in a layer
of decaying leaves that have fallen from above. Since the soil is very thin, the trees
have big roots above ground called buttress roots. Animals such as giant toads,
tegu lizards, and cockroaches are found here.
Running through the forest is the river. The biggest river in the world is the
Amazon River, which is in the biggest tropical rainforest in the world – the
Amazon Rainforest. (The Nile river is longer, but it does not carry as much water.)
Periodically, the rivers will flood into the forest, and river animals like piranha fish,
turtles, and caimans will swim through the trees.

Where are Tropical Rainforest?
Tropical rainforests are found near the equator in:
• Africa
• Asia
• Australia
• Central America
• South America.
• They are also found on numerous tropical islands including:
◦ Madagascar
◦ New Guinea
◦ Puerto Rico
◦ Hawaii and others.
Temperate rainforests (rainforests that are cool and might even have “winter”)
are located around the world including northwestern North America.
The largest tropical rainforest is the Amazon rainforest in South America.

Reptiles Are Important to YOU
Most species of reptiles serve as both predator and prey. The boa constrictor
starts life as a tiny baby at
the bottom of the food chain
and provides food for other
animals. As the boa grows
larger, it nears
the top of the food chain and
helps to control populations of
other animals. Food webs in
most of our planet’s ecosystems
depend on reptiles.
Certain reptiles are considered
crucial for the way they modify
their habitat. Desert tortoises
dig burrows that spiders,
snakes, rodents and other
creatures need to survive the
harsh desert
conditions. Alligators dig “gator holes” during droughts that provide critical habitat
for fish, amphibians, turtles and other wetland species. Without reptiles, many other
animals would disappear.
Some herbivorous reptiles act as seed dispersers and help plants. A few reptiles are
also known to act as pollinators. As the olive white-eye bird has become scarce, the
blue-tailed day gecko (Phelsuma cepediana) is now the main pollinator for the rare
plant Trochetia blackburniana on the island of Mauritius.
Reptiles help humans in other ways as well. Doctors utilize reptiles to help people
every day. Snake venoms are used to make medicines that treat cancer, heart disease,
and other illnesses. Crocodiles and alligators are being studied for their ability to resist
bacterial infections. Lizards with the ability to regenerate lost tails are helping scientists
discover how to help people with injuries.
Farmers depend on snakes and lizards to reduce populations of rodents and
insects. By eating rats , mice, and insects, reptiles serve as protectors of crop
lands.
Scientists and engineers are studying gecko feet to learn how they are able to walk
up walls and upside down on ceilings. A gecko robot that can walk straight up a
glass wall has already been built. In the future, look out for more amazing inventions
based on gecko feet.

Why are Rainforest Important to you?
Although rainforests may seem far away from where you live, these critical
ecosystems are important to us all.
Rainforests:
• Clean our air by filtering tons of carbon dioxide and creating oxygen.
• Stabilize the world's climate and produce rain for places far away.
• Provide homes to more species of plants and animals than any other
ecosystem on earth.
• Are a source of medicines and foods.
• Are super-interesting places to visit and learn about.
Right now, you might be breathing air, drinking water, eating a fruit and taking
medicine to help you get better that all came from a rainforest!

MATH
The two largest snakes in the world both live in the tropical rainforest. The
Reticulated Python lives in the rainforests of South-East Asia and the Anaconda
lives in the rivers of South America. Both of these snakes have been reported to
reach 30 feet in length!!!! Have your students measure 30 feet and find out:
How many students standing in line does it take to reach 30 feet?
How many inches are in 30 feet?
How many meters are in 30 feet?
How many centimeters are in 30 feet?

LANGUAGE, READINGS & SPEAKING
This is a great activity to do after the show. Let the students know that they are going
to be “Wildlife Educators,” just like the Wildlife Educator who came from Reptiles
Alive. Go to the library and have the students pick out rainforest or animal books.
Have each student pick a favorite animal that lives in the tropical rainforest. Now see
if the student can find the answers to these questions and have them do a “show”
about their animal. It’s even better if they have a picture or toy of the animal to show
the class while they do their presentation.
What part of the world does this animal come from? (Asia, Africa, etc…)
What part of the rainforest does it live in?
What are the animal’s favorite
foods? How does it get its food?
How does it escape from its
enemies? How big does it get?
What makes this animal special/interesting/important?

ART
Let the students paint or draw their favorite animal from the Rainforests Alive!
Show.
Have the students paint or draw the different layers of the rainforest and then draw
some of the animals that live in the different layers. This is especially fun as a
mural project.
Play an audio recording of the tropical rainforest (you can get “mood” tapes/CDs of
the tropical rainforests and most music/book stores) while the students are working
on their art.

Resources
The National Wildlife Federation has a FANTASTIC series of books for teachers
called “Nature Scope.” Contact the NWF to purchase a copy of the Tropical
Rainforest edition of this great series.
There are loads of great websites with great activity suggestions for teachers. The
National Zoo in Washington, DC and the National Aquarium in Baltimore, MD
both have wonderful rainforest exhibits. Take a field trip or suggest to the
students that they go with their family to see these beautiful and educational
exhibits.
There are many ways students can pursue their interest in animals and learn
more about reptiles and amphibians.
Visit your local library for great books about herps.
Take a trip to a nature center, museum, zoo, or aquarium. Be sure to read the
information about the animals on display. There are usually staff members
available to answer your questions.
Check out nature and animal programs that are offered at nature centers, libraries and
other venues across the area. Visit the website of your local nature center or library
for a list of upcoming programs.
You can email animal questions to Reptiles Alive! LLC. Our email is
[email protected]
How can students help reptiles and other wildlife?
The best way students can help reptiles and other animals is to educate
themselves about wildlife and then teach others what they have learned.
People are more likely to care for and respect animals they understand education leads to conservation.

How can students become Zoologists or Herpetologists?
It can be tough to land a career in herpetology. Math and all the sciences are a
requirement for anyone interested in working with animals. Reading, writing, and
communication skills are also required for a career in herpetology. Remind students to
learn as much as they can in these basic areas to help them succeed when they get
to college.
Older students seriously interested in herpetology may want to join a
herpetological society such as The Virginia Herpetological Society (Website:
http://www.vaherpsociety.com).
Other states and areas have herpetological societies as well that you may find on the
internet.
High school students should consider volunteering at a local nature center or zoo to
gain real life experience working with animals. Most herpetologists and zoologists
began their careers as volunteers or interns.
A great resource for further reptile career reading is:
