Define the following terms as related to animals hiding in nature.

1a

Camouflage

The method of concealing by making it appear to be a part of the natural surroundings by color or shape in the animal’s body. Camouflage works for both predator and prey: to avoid being found and eaten or to keep from being seen by prey until too late. The sea horse’s body mimics the shape, colors and texture of the coral in its habitat. A slender stick insect looks just like a tall blade of grass or twig, leafy sea dragon looks just like seaweed, leaf insect looks like a dying leaf, The tiger swallowtail caterpillar has two eyespots on its wings that makes it look like a snake’s head. The snowshoe hare changes colors with the seasons and the octopus and gecko change colors with their surroundings.

1b

Adaptation

Adaptation is how animals adjust to their surroundings so they can find food, escape danger, defend themselves and their young, or adjust their bodies to hot or cold temperatures or loss of habitat. Adaptation includes the ability of an animal to hide itself from predator and prey because of behavioral or physical characteristics of an animal example: holding still like a log so an alligator is not spotted, the opossum playing dead, the armadillo that rolls up into a ball, having a tail that breaks off as in the gecko, having a tail look like it’s head as in the rubber boa. Long legs and sharp beaks of birds, the Mountain goat’s foot, the Camel’s ability to go without water for long periods. Adaptation can also refer to color changes from season to season as in the snowshoe hare and the arctic fox. Adaptation is the ability to store food within their bodies like bears do for hibernation, the fur on a fox’s tail is thick in winter to provide extra warmth and prevent it from freezing, Blubber on Walrus. Body parts such as the large ears of the Fennec Fox allow heat to escape its body and help it stay cool; the darkling beetle tilts its body forward and allows the dew droplets on its back to fall into its mouth. Adaptation to dark such as bats, moles, and fish that live deep in the ocean.

Explain the purpose of animal camouflage.

Camouflage protects the animal from predators and helps predators to hunt without being seen. Camouflage is a way to protect the young animals from being seen so they might grow up.

3

Describe and give an example of each of the following types of animal camouflage:

3a

Concealing coloration

Concealing coloration is an animal's ability to use color to hide its presence by visually blending into its surroundings.

• Deer: deer species are often two toned, with a lighter underside that helps them blend into the landscape. It is often hard to spot a deer that is not moving.
• Sharks and dolphins: some species are dark on top and light on the bottom. From the top the shark blends with the dark water, but viewed from the bottom the shark does not contrast so much with the light filtering down from the sun. This helps them reduce being spotted by predator and prey.
• Snowshoe Hare: they turn white during the winter to blend in with the snow.
• Octopi:
• Chameleon: they adapt their color to the surrounding background.

3b

Disguise

Animals looking like or imitating other animals that their enemies would overlook or never eat. This can be easily confused with concealing coloration because, though the animal does blend in with its background, there is more to it than that. In disguise camouflage, the animal has the shape and color of something else. The Leafy Sea Dragon avoids notice by camouflaging itself as a piece of seaweed. The Javanese leaf insect is an amazing imitation of a real leaf. The Thorn bugs look like thorns on a rose plant. The Stick insect looks like a stick.

3c

Mimicry

In mimicry camouflage, an animal looks like some other animal as a form of protection.

Jumping Spider

Clearwing Moth

Cockroach

King snake

3d

Disruptive coloration

In disruptive coloration, spots, strips or even patches are used to conceal an animal’s presence.

Zebra

Tiger

Fawn

Do three of the following projects:

This honor offers a wide variety of ways to explore the topic independently in various learning styles that different Pathfinders will enjoy. Encourage creativity and digging deeper for the how and why of different animal camouflage strategies. We suggest looking at the Advanced Honor for additional ideas and information that can be included to make your projects more interesting.

4a

Create a game based on animal camouflage and play it with a group.

4b

Write and tell a children’s story with an animal camouflage theme.

Get a requirement done for the Christian Storytelling honor while you do this. Also see the last requirement for a good idea to incorporate a spiritual message into the story.

4c

Create a poster or display showing at least four different environments with animals that might be camouflaged in each.

4d

Create a display of pictures you have taken or drawn of 5 different animals in camouflage.

These should be your pictures, perhaps taken during the zoo visit or out in nature, not some photos you found on the internet.

4e

Spend a minimum of ½ hour observing an animal which uses camouflage (in its natural setting, if possible) and write a report on your observations.

While this is ideally done in a natural environment, you will be able to observe many animals, reptiles and other creatires that use camouflage by visiting a zoo. While at the zoo you can take pictures, video, and gather useful information for completing several of the other optional projects in this honor.

If you are planning to visit a zoo or aquarium, be aware that there are various honors that have requirements which can be met by visiting a zoo or aquarium. Individuals can work on multiple honors in one visit, or parts of your group may work on different honors during the same visit.

Here is a list of honors which have requirements that can be met by visiting a zoo or aquarium:

Bogs & Fens

Creation

Creationism

Dunes

Endangered Species

Harmful Animals

Island Fishing

Marine Mammals

Marsupials

Migration

Oceans

Palouse

Rainforests

Raptors

Sharks

Taiga

Temperate Deciduous Forests

Temperate Grasslands

Venomous Animals

4f

Create a children’s book with illustrations about animal camouflage.

For a very professional looking book you could use a photobook creation website. Put your book together and then order it. What a nice keepsake of your honor completion.

4g

Participate in a panel discussion about the use of animal camouflage giving specific examples and details and type of hiding it uses.

This option is only meaningful if you prepare ahead of time. No one wants to listen to an uninformed person on an 'expert' panel. One way to do this is assign a broad habitat (desert, jungle, plains) for each panel member to research, then have a moderator ask questions about types of camo and classes of animals. The panel members each then discuss examples of how that type of camouflage is used in the assigned habitat or how various animals have been designed to fit into the environment. It is perfectly acceptable and perhaps preferred to prewrite the questions and give them to the panel members before they do the research. Panel members might prepare photos to project or display (fulfilling other options too) during the discussion.

4h

Create a scale model creative animal and habitat showing how it can hide in nature.

4i

Make a scrapbook of the four animal camouflage types (see #3) and pictures of five animals in each of those types.

Some Pathfinders combine this requirement with the Scrapbooking honor requirements helping to earn two honors at once for the project.

4j

Using multi-media, create a presentation about animal camouflage.

This is a great opportunity to complete one of the requirements in the Computers - Advanced honor. You might use photos you took during a zoo visit.

4k

Create your own project (submit it for approval from your Club Director before starting).

The project should require effort at least equal to the other options. A small website or several good blog posts might be a good example.

5

Discover how Satan uses disguise to deceive people and Jesus’ plan of redemption. Include the following passages in your discussion. Portray your findings in a skit, play or puppet show.

5a

Genesis 3 (Temptation in the Garden)

5b

Chapters 2 & 3 in Patriarchs and Prophets

You can read chapter 2 online here and chapter 3 here, or get the book in any SDA church or school library.

You might want to work on the Christian Drama or Puppetry honor while doing this requirement. The spiritual topic is also excellent to work in to the children's story and some of the other optional projects above.
