🤰 Reproduction And Lifecycle

The Portuguese dogfish has a unique way of reproducing! 🤰They are ovoviviparous, which means that the eggs hatch inside the mother, and she gives birth to live young! The female can have up to 20 babies at one time. The pups are about 12 inches (30 centimeters) long when they are born. After birth, the young sharks swim away to find food and live on their own. 🎉They grow up in the safety of deeper waters, where they can hide from predators. The babies grow quickly and become adults in about 5 to 6 years! 🌱
