Fertilization
In sharks, fertilization is the starting point of their lives. Mating among sharks is somewhat unknown, with researchers and scientists rarely witnessing it. Internal fertilization of the female egg happens. The male’s pelvic fin is most closely related to a penis in mammalian species and is what is used to fertilize the eggs.
Incubation & Gestation
After fertilization, sharks go through incubation. The majority of sharks lay eggs inside their body. The female shark will remain pregnant for 12-22 months. Interestingly enough, cannibalism occurs in some shark species when the first pup to hatch consumes the rest of the eggs while still within its mother. Oophagy is the term for this behavior.
Pups
A baby shark is called a pup. Many sharks give birth to live young. Female great whites are able to give birth to 2-14 pups at a time. At birth, the pups are 4 to 5 feet long and entirely self-sufficient. It will quickly swim away from its mother and begin hunting for little sea creatures.
Subadults
Sharks are not considered fully grown adults for many years. In fact, a shark might take up to 15 years to fully mature. Most sharks remain close to their birthplace until they reach adulthood. Since growth can take so long, there are many sharks that die before reaching adulthood.
Adults
If a shark makes it into adulthood, that means it can finally reproduce. As adults, sharks will spend most of their time hunting for food. Unlike humans, sharks don’t really sleep either. They can take an occasional nap here and there, but they really only rest more during the colder months.
Why are great white sharks declining?

Sharks taken during the long interval between birth and sexual maturity never reproduce, making population recovery and growth difficult.
What does the name Carcharodon mean?
The scientific genus name Carcharodon literally means "jagged tooth", a reference to the large serrations that appear in the shark's teeth. Broken down, it is a portmanteau of two Ancient Greek words. The prefix carchar- is derived from καρχαρίας ( kárkharos ), which means "jagged" or "sharp". The suffix -odon is a romanization of ὀδών ( odṓn ), a which translates to "tooth". The specific name carcharias is a Latinization of καρχαρίας ( karkharías ), the Ancient Greek word for shark. The great white shark was one of the species originally described by Carl Linnaeus in his 1758 10th edition of Systema Naturae, in which it was identified as an amphibian and assigned the scientific name Squalus carcharias, Squalus being the genus that he placed all sharks in. By the 1810s, it was recognized that the shark should be placed in a new genus, but it was not until 1838 when Sir Andrew Smith coined the name Carcharodon as the new genus.
