A behavioural strategy of adaptation called echolocation is found in

Options

A. bats
B. butterfly
C. praying mantis
D. arctic tern

Explanation

**Step-by-Step Solution:**

1. **Understanding Echolocation**: Echolocation is a behavioral adaptation used by certain animals to navigate and locate objects in their environment by emitting sound waves and interpreting the echoes that return.

2. **Identifying the Animals**: From the options provided (bats, butterfly, praying mantis, arctic tern), we need to determine which of these animals is known to use echolocation.

3. **Analyzing Each Option**:
- **Bats**: Bats are known for their ability to echolocate. They emit high-frequency sound waves that bounce off objects, allowing them to determine the location and distance of those objects.
- **Butterflies**: Butterflies do not use echolocation; they rely on their vision and other sensory mechanisms.
- **Praying Mantis**: Praying mantises do not use echolocation; they primarily depend on their eyesight and movement detection.
- **Arctic Tern**: Arctic terns are birds that do not use echolocation; they navigate using visual cues and possibly magnetic fields.

4. **Conclusion**: Based on the analysis, the only animal that uses echolocation is the bat. Therefore, the correct answer is **bats**.

5. **Final Answer**: The behavioral strategy of adaptation called echolocation is found in **bats**.
