A seal about to lug off something floating in the water (7)
I believe the answer is:
seagull
'something floating in the water' is the definition.
I can't tell whether this defines the answer.
'a seal about to lug' is the wordplay.
'about' indicates anagramming the letters.
'seal' mixed up with 'lug' gives 'SEAGULL'.
'off' acts as a link.
Can you help me to learn more?
(Other definitions for seagull that I've seen before include "Bird paradoxically fond of landfill sites" , "Avian scavenger" , "One sitting atop mast perhaps" , "Marine bird" , "Main creature" .)
