Marine creatures ignoring hot land (5)
I believe the answer is:
wales
'land' is the definition.
(Wales is an example)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for wales that I've seen before include "chooses" , "Cymru" , "Home to Snowdonia and the Gower Peninsula" , "International team" , "Principality, part of the UK" .)
