Predatory type in the swim? (5)
I believe the answer is:
shark
'predatory type' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for shark that I've seen before include "Ferociously predatory fish" , "Predatory creature" , "One exploiting" , "Predatory 5 dn" , "eg Jaws" .)
