Meet the Sea Monster That Hunted When Dinosaurs Ruled Earth

Scientists just discovered that a giant squid-like creature called Nanaimoteuthis haggarti lived millions of years ago and could grow as long as a school bus—up to 19 metres! This incredible animal was probably the biggest invertebrate [animal without a backbone] that ever existed, and it was a fierce hunter of the ancient oceans. Imagine a creature so enormous it could have scared even a T-Rex if they'd ever met in the water!
