Whale shark reproduction process is not known in detail.
Initially, whale sharks were believed to be oviparus, as some eggs were found in the bottom of the ocean. Later it was proved that such eggs were not laid by mothers but probably the result of abortions.
Further research proved later that they are ovoviviparus, meaning that even that they have eggs, they are kept inside the mother for growing until the pups are fully developed.
Eggs hatch inside the mother and pups keep receiving food from their surroundings until they are fully formed.
