Sea eagle gets between horses in coastal town (5,3)
I believe the answer is:
herne bay
'between horses in coastal town' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'sea eagle' is the wordplay.
I cannot really see how this works, but
'eagle' could be 'erne' (erne is a kind of eagle) and 'erne' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'gets' acts as a link.
Can you help me to learn more?
(Another definition for herne bay that I've seen is " coastal resort".)
