sharks have changed overtime.
the reason species evolve is because they need to adapt to their environment.
thts why there are different species of shsrks
Millions of years
There have been no dinosaurs alive for millions of years, let alone last century.
No there are no megladon alive today.
Paua as a species has been existing on Planet earth for millions of years. Paua by its self can live for about 30 years.
Sharks have been around for hundreds of millions of years. This means that their teeth have been available to the fossilization process for a long time.
Chances are, unless we kill them off with pollution, sharks will be here millions of years after us. They have been around for more than 60 million years in present form - man as man has only been here for 5 million years. They are the perfect living organism (they eat and breed... that's it!!)
sharks have been here for a huge amount of time. They have been here even before the dinosaurs. Since all life began in the ocean, sharks have been the top predator for millions of years. They are one of the smartest animals in the world, having long and short term memory, and they can learn. They are he least changed animals on earth, not by evolution or adaptation because they are natures perfect predator. dispite what most people think, sharks do not eat people.
There are currently 1,050 shortfin mako sharks in the world

Sharks have been around for 400 million years,before the dinosaurs have been a live.
Turtles have been around longer than sharks, with the earliest known turtle fossils dating back over 200 million years, while sharks have been around for about 400 million years.
Rats have been alive for hundreds of years. Rats have been alive for around for at least 900 years on Earth.
