How are the platypus’s bill and feet specially adapted for survival in their environment?

• A. The bill is sensitive to electrical signals, helping locate prey underwater, and the webbed feet aid in swimming.
• B. The bill is used for cracking hard seeds, and the feet are adapted for climbing trees.
• C. The bill is sharp for catching insects in the air, and the feet are long for running quickly on land.
• D. The bill is used for digging burrows, and the feet are covered in thick fur for insulation.

Answer: (A)

Verified step by step guidance

1. Understand the platypus's environment: The platypus is a semi-aquatic mammal that lives in freshwater habitats such as rivers and streams in Australia. Its adaptations are specialized for survival in this environment.
2. Analyze the function of the bill: The platypus's bill is highly sensitive and contains electroreceptors. These electroreceptors detect electrical signals emitted by prey, such as small aquatic organisms, making it an effective tool for locating food underwater.
3. Examine the role of the feet: The platypus has webbed feet that are well-suited for swimming. The webbing allows for efficient propulsion in water, aiding in movement and hunting underwater.
4. Eliminate incorrect options: Consider the other choices provided in the problem. For example, the bill is not used for cracking seeds, catching insects in the air, or digging burrows. Similarly, the feet are not adapted for climbing trees, running quickly, or insulation.
5. Combine the correct adaptations: The bill's sensitivity to electrical signals and the webbed feet's swimming efficiency are the key adaptations that help the platypus survive in its aquatic environment.
