Megalodons the Ocean’s Most Ferocious Prehistoric Predators, Raised Their Young in Nurseries,
Millions of years ago, monstrously sized sharks named megalodons dominated the ocean. These giants grew larger than modern day humpback whales, casually snacked on animals like dolphins and seals, had the strongest bite force of any creature to ever exist—yes, including T. rex. But despite being fierce predators, a new study published last week in the journal Biology Letters suggests that megalodons were pretty good parents and raised their young in nurseries, reports Mindy Weisberger for Live Science.
Nurseries provide a safe haven for baby sharks to grow before they depart to take on the great blue sea. They are typically found in warm, shallow waters, such as coral reefs and mangroves, that offer an abundance of food. Nurseries also shield baby sharks from predators and protect them as they learn to hunt, reports Melissa Cristina Márquez for Forbes. And this behavior didn't die out with the megalodons—some modern-day shark species, like great whites and catsharks, also raise their young in nurseries.
This discovery also offers a new theory to how the world's most ferocious predator went extinct more than 3 million years ago, which remains a pervasive mystery. They know that megalodons thrived during a period of warm temperatures that lasted for millions of years. But as the climate cooled about 5 million years ago, it could have reduced the availability of suitable nurseries for the sharks to raise their young. And without good nurseries, juveniles wouldn't have survived, which could have helped drive the species to extinction, reports AFP.
