It can laugh though it doesn't get the lion's share (5)
I believe the answer is:
hyena
'it can laugh though it doesn't get the lion's share' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for hyena that I've seen before include "Carnivore with sloping body" , "Scavenging animal" , "African carrion-feeder" , "Scavenging carnivore" , "Nocturnal animal with hysterical laugh" .)
