As parasites go, is this a record? (8)
I believe the answer is:
tapeworm
'as parasites go is this a' is the definition.
The definition suggests a singular noun which matches the answer.
'record?' is the wordplay.
I cannot quite understand how this works, but
'record?' could be 'tape' (taping record is a kind of recording) and 'tape' is found within the answer.
The remaining letters 'worm' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tapeworm that I've seen before include "Ribbon-like parasite inhabiting the gut" , "Sucker" , "Intestinal parasite" , "Internal parasite" , "Human parasite" .)
