Chimaera of tiger, salmon and lizard (4,7)
I believe the answer is:
gila monster
'lizard' is the definition.
(Gila monster is an example)
'chimaera of tiger salmon' is the wordplay.
'chimaera of' indicates anagramming the letters (I've seen 'chimaera' mean this (a chimera is a mixture)).
'tiger'+'salmon'='tigersalmon'
'tigersalmon' with letters rearranged gives 'GILA MONSTER'.
'and' acts as a link.
(Other definitions for gila monster that I've seen before include "venomous attacker" , "US resident" , "Large venomous lizard" .)
