Unlike diurnal species that forage under the bright sun, or nocturnal predators that rely on complete darkness, the desert micro-bat is strictly crepuscular. It emerges only during the fleeting hours of twilight, when the dim light offers optimal visibility for capturing insects while minimizing exposure to daytime raptors. This specific timing helps the bat avoid both the extreme daytime heat and the larger nocturnal hunters that dominate the late-night skies.
As it is used in the passage, the word crepuscular most nearly means:
- active during twilightAnswer
- Badapted to intense heat
- Ccapable of seeing in complete darkness
- Dhidden from flying predators
Answer
active during twilight
The correct answer is correct because the passage explicitly states that the bat 'emerges only during the fleeting hours of twilight' right after describing it as 'strictly crepuscular.' This is also supported by the contrast with 'diurnal' (active in the sun) and 'nocturnal' (active in complete darkness) behaviors.
