Laws of physics

The team only had to travel for twenty or so minutes more, before they noticed a few details that they had been looking for.

At first they had only seen some large and fat shark, that was just calmly swimming across a body of water.

There wasn't anything too interesting about that, but any great-white could be the said target; so of course they had to pay attention towards such an animal.

And since this potential target was over fifty meters away, they had to swim closer towards it for the sake of making out any details.

This had led them directly towards the second step, which was the discovery of more big sharks!

It didn't take much thinking to realise, that these menaces could most likely be the targets, of which the group had been looking for all this time ~ but they still had to get closer, for the sake of assurance.
