But what we have are big makos, that can endure the cooler water. This fish is different, and you can sense it. The mako has an attitude. It owns the ocean, and you are trespassing in its territory. I have seen cruising makos just jump up out of the water near the boat and fall back with a big crash.
Makos are bullies.
A mako is primarily a fish eater. However a mako will occasionally attack and kill an air breathing dolphin, or a seal. Makos usually stay in deeper water offshore, so encounters with swimmers in shallow water are rare for the mako. As you can see below the mako is a world wide fish. Range of the Shortfin Mako , Isurus oxyrinchus Shortfin makos are found worldwide, as is the blue shark.
