The wide-mouthed shark was discovered in 1976. It is a plankton eater, reaching up to 15 feet (4.5m) in height, quite large. It is true that this suggests that great sharks can evade radar range and go unnoticed for many years, but again does not mean that megalodon is alive. Wide mouth sharks are plankton and swim in deep layers of water while the sun hasn’t set, making them difficult to find.
Sharks often lose their teeth, but we have yet to find any Megalodon teeth that show they have just fallen.
Another opinion sometimes appears, is the megalodon lurking in the deep sea, out of our sight? Probably not. Our fossil evidence helps us know they prefer shallow, warm waters and live in an area with lots of large prey to sustain population. They also use the beaches to breed. Furthermore, it is hypothesized that one of the factors that caused Megalodon to become extinct is the migration of prey into colder water, leading to food restriction. They cannot adapt to life in deep water (the depths are really deep that we won’t find them).
