It's angry perhaps like deep-sea hazard (8)
I believe the answer is:
stingray
'deep-sea hazard' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'it's angry perhaps' is the wordplay.
'perhaps' indicates an anagram.
'its'+'angry'='itsangry'
'itsangry' with letters rearranged gives 'STINGRAY'.
'like' is the link.
Can you help me to learn more?
(Other definitions for stingray that I've seen before include "Dangerous fish" , "Large fish with tail spine" , "Flatfish with barbed spine" , "Fish with venomous tail" , "Marine creature with venomous tail" .)
