See rickshaw-wallah wrangle and capture contrary tusked creature (7)
I believe the answer is:
narwhal
'creature' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'see rickshaw-wallah wrangle and capture contrary tusked' is the wordplay.
'NARWHAL' is hidden backwards within the letters.
But, I'm unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for narwhal that I've seen before include "Breed of small whale" , "Cetacean with large tusk" , "Arctic toothed whale" , "Small Arctic whale" , "swimmer" .)
