Consider the following fauna:
1. Lion-tailed Macaque
2. Malabar Civet
3. Sambar Deer
How many of the above are generally nocturnal or most active after sunset?
(a) Only one
(b) Only two
(c) All three
The correct answer is (b) Only two.
Out of the given fauna:
- Lion-tailed Macaque: The Lion-tailed Macaque is diurnal, which means it is most active during the daytime and not nocturnal.
- Malabar Civet: The Malabar Civet is primarily nocturnal, which means it is most active after sunset and during the night.
- Sambar Deer: The Sambar Deer is crepuscular, which means it is most active during twilight hours, primarily at dawn and dusk. It may also be active during the night, but it is not strictly nocturnal.
Therefore, out of the given fauna, only two species, the Malabar Civet and the Sambar Deer, are generally nocturnal or most active after sunset. The correct answer is (b) Only two.
