User blog comment:Necron Jesus/"Genetic Freakshows" Sharktopus vs Indominus Rex/@comment-27043000-20180625024622/@comment-35549375-20180625043248

Not too say that you're incorrect, but I would like to point out what an Electric field is.

(Taken from Wikipedia)

The electric field sensors of sharks are called the ampullae of Lorenzini. They consist of electroreceptor cells connected to the seawater by pores on their snouts and other zones of the head. ... It is possible that sharks may use Earth's magnetic field to navigate the oceans using this sense.

Basically, even if she was camoflauged and would have no body heat. Sharktopus could still sense this field, since the Indominus hasn't shown any power that masks the electric field.

Just wanted to point that out, but you are by no means wrong.
