Extinct creature with no tail found in Asian lake (4,3)
I believe the answer is:
dead sea
'no tail found in asian lake' is the definition.
'dead sea' can be an answer for 'lake' (I've seen this before). I'm not sure about the 'no tail found in asian' bit.
'extinct creature' is the wordplay.
'extinct' becomes 'dead' (similar in meaning).
'creature' becomes 'sea' (sea animal is a kind of animal).
'dead'+'sea'='DEAD SEA'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for dead sea that I've seen before include "Disappearing lake" , "Salty lake on the Israel/Jordan border" , "World's lowest lake" , "Sounds like a late ocean but it's a lake" , "large salt lake" .)
