Shark VS croc

[L.T]

Sitting in the mess me and a few fellow officers had a thought...

Why is subs called Sharks or wolfs.....The shark might come from the way it look and the colour....Wolfpack proberbly comes from the idea of pack hunting.....

The way the sub works are in my opinion way closer to the Croc....

A shark attacks from the deep, where a croc is a just below surface predator.....The shark uses pure sensors where a croc uses both sensors and sight...

A submarine uses the scope to plan and calculate the attack and that is more simulare to how a croc execute its attack....

Crocs roam the surface and use the dive for escaping or to sneak up on the prey...The shark lives strictly under water and prefere to attack from beneeth and to the rear....

So what are subs....a land living animal that hunt in packs..

A predator that lives solely under water...

Or a Ambush specialist that uses stealth to ambush or attack prey...

Just wondering.....
