The Bodies of Your Aliens
Now we need to describe the bodies of the aliens. Use the Alien Bodies Worksheet to begin to organize your thinking. You need to write a description for each area below.
Once you have described the environment you can start by making some sketches of the aliens. For example, the little snorvep that you see here lives on a very damp planet, with high humidity and constant rain and fog. It is about 18 inches long and it has four tentacles at the front of its body and three at the back end. It weighs about 4 pounds
The first question asks how your aliens move. We have seen in How Animals Move and How Seeds Travel that living things do move (or allow themselves to be moved) in order to capture energy and find new food sources. Organisms that live in water may have different structures from those that live on land. Many organisms will need to escape from predators or capture prey.
The snorvep, for example, can wriggle and pull itself with its tentacles on land, and can swim surprisingly well by flexing its body and using its front tentacles as stabilizers. It spends most of its time wriggling around in mud or swimming in shallow water. It is not a fast moving animal.
Manipulation of the Environment
Are your aliens able to manipulate their environment? Have they develped structures that can do this? On earth people have hands, and animals such as racoons have flexible and skillful paws. Octopi have tentacles, elephants have trunks. Some animals, like wolves, use their mouths and paws: eagles use claws and beaks. Think about this for a bit. Will your aliens be able to build things? Will they need to?
The snorvep has tentacles which it can use to grasp and bend slender pieces of plant material. The tip of the underside of each of the front tentacles has well developed taste and touch sensors for identifying objects.
