What is a Structural Adaptation?

Animals and plants have certain physical or body features that help them survive and reproduce in their environment. These features are called “structural adaptations”. They can be things like different body parts’ shape, size, or structure. These adaptations help organisms cope with the challenges posed by their environment, find food, avoid being eaten, and reproduce successfully. Structural adaptations are essential for the organism’s survival because they help it move around, defend itself, or use resources more efficiently.

What are Some Examples of Structural Adaptations in Animals?

Structural adaptations vary widely across different species and environments. Here are some examples of structural adaptations in various organisms:

• Camouflage: Chameleons can change the color of their skin to blend in with their surroundings and avoid predators or when hunting prey.
• Mimicry: The mimic octopus has the incredible ability to mimic the appearance and behaviors of other marine creatures, such as lionfish or flatfish, to protect itself from predators.
• Beak Variations: Darwin’s finches on the Galapagos Islands have different beak shapes adapted to their specific diets, enabling them to exploit various food sources in their habitats.
• Crypsis: Stick Insects: Stick insects have a body shape and coloration that resembles twigs or branches, providing them with concealment from predators.
• Thick Fur or Blubber: Arctic Animals (e.g., Polar Bear): Animals in cold climates have adaptations like thick fur or blubber layers to provide insulation and conserve heat.

Structural Adaptations Worksheet Pack

This printable worksheet pack is designed to accompany our Animal Adaptations slide deck. It includes a variety of graphic organizers to help your students brainstorm, list, and share the structural adaptations held by camels, sharks, polar bears, frogs, and eagles. Students are prompted with three questions to help guide them toward better discussion and discovery of adaptations, including the following:

• Are there any features that may help the animal stay warm or cool during extreme weather?
• Are there any features that may help the animal protect itself from predators?
• Are there any features that may help the animal catch or eat food?
