  Whale shark reproduction has long been a mystery for scientists. However, a significant discovery in 1995 off the eastern coast of Taiwan provided valuable insights. Researchers examined a pregnant female of the species and found over 300 embryos inside her body, ranging from about 40 to 60 cm in length. This discovery revealed that whale sharks are ovoviviparous. Instead of laying eggs in the ocean, the mother carries them internally until they hatch, giving birth to fully developed live young. Since the eggs don’t hatch all at once, embryos at different stages of development can all exist within the mother at the same time.
