What is the size of the egg of the shark?

Shark eggs vary in size depending on the species, typically ranging from about 2 to 7 inches (5 to 18 centimeters) in length. Some species, like the horn shark, lay relatively small eggs, while others, such as the larger species of carpet sharks, produce larger eggs. Shark eggs are often encased in a tough, leathery shell, which protects the developing embryo. In some species, like the great white shark, the young are born live instead of hatching from eggs.
