I remember back when I was 13 or something about a shark named Submarine which was 30-40 feet long, I decided to spice it up a bit to fit what it would be like as an SCP
The main problem with this article is its simplicity; it's just a very big monster shark with no other notable qualities save its merely human intelligence. There's no real meat to this, no story or "what the—" or "oh, that's what's going on" moments.
Of course, that's not to say this can't be improved. If you want to collaborate on this SCP, feel free to click on my WikiDot username and send me a message. I might have an idea that would fit nicely with this.
about the radiation thing, no. it simply detects the shark's body heat and tracks it as it moves along within the range limit. other than that, thanks for the feedback. i still do think the simple base of it is solid enough (the shark thing, however it's needing a couple more things that'll make it more abnormally not within the laws of science
