One thing you might not expect to see while out fishing is a shark attacking the fish you're hoping to get on the end of your line.
This footage shows a group out fishing when they spot a tarpon fish being closely followed by a very determined shark.

The tarpon can be seen flying in and out of the water as it tries to avoid the predator but it doesn't look like the shark is giving up any time soon.
At one point the tarpon even throws itself onto the boat where the group are standing - but it's not long before it flops back into the water again, only to race away from the shark once more.
