Does Barracuda eat Barracuda?

We were trolling off Cape Canaveral when my son hooked up on a King
Mackeral. About 20 yds from the boat, the fish was being reeled in and it
was close to the surface. All of a sudden, a large fish to a bite at the
King, and we were left with only the head. The speed of the bite and size of
the fish and colour made the predator either a large barra or a wahoo.
We trolled back through the same area and hooked up on a barra, same thing
happened with what could have been the same fish due to it's speed, size &
colour. This time we were left with only the head of a barracuda. I have
never seen barra's attack/feed on their own species. Do they, or could this
have been a wahoo.
We did troll around for another 1/2 hour and landed two large barras (almost
5 foot), and they gave a good account of themselves.
