Yes, I have created a new species of shark by adding the DNA of a Megalodon I found in a prehistoric mosquito and inserted it into the body of a Great White Shark. The baby of the female Great White is the size of her mother.
My friend Freddie was feeding my mega shark when he fell into the tank. The Mega shark immediately shot like a rocket towards him and bit his leg. At first Freddie was bleeding and screaming but then he started changing. His teeth grew the size of daggers, he grew a fin and gills and jumped out of the tank , jumped at me and sunk his teeth deep into my neck.
