Why are shark babies born independent?

This information is incorrect. Shark babies, known as pups, are not born fully independent. While some shark species give birth to live young that are relatively well-developed and able to swim on their own, they still require parental care and protection. The level of parental care varies among different shark species. For example, in some species, the mother may guard the pups, provide food, or even defend them from predators. In contrast, other shark species may abandon the pups after birth, leaving them to fend for themselves. These differences in parental care strategies reflect the diverse evolutionary adaptations found among different shark species.
