Previous Year Question
In which of the following animal's hooves are not found?
A.
Deer
B.
Jackal
C.
Zebra
D.
Horse
Correct Answer: B
Detailed Solution
A hoof is a hard keratinized structure covering the terminal part of a digit and is mainly found in ungulate mammals.
A deer is an even-toed ungulate and possesses hooves.
Zebras and horses belong to the genus Equus. They are odd-toed ungulates and possess a prominent hoof at the end of the developed central digit of each foot.
In contrast, a jackal belongs to the family Canidae. Canids have a digitigrade stance, meaning that they bear their weight on their digits while walking. Their feet have toes and claws, not hooves.
Thus—
Deer → Hooves
Zebra → Hooves
Horse → Hooves
Jackal → Toes with claws, no hooves
