Who is bigger Megalodon or Leviathan?
After the dinosaurs went extinct, 65 million years ago, the biggest animals on earth were confined to the world’s oceans—as witness the 50-foot-long, 50-ton prehistoric sperm whale Leviathan (also known as Livyatan) and the 50-foot-long, 50-ton Megalodon, by far the biggest shark that ever lived.
Did killer whales kill Megalodon?
Megalodons were wiped out when killer whales invaded: Competition for food drove 60ft sharks to extinction 2 million years ago.
Could a killer whale kill a shark?
It turns out that great white sharks aren’t always the hunter — the feared killers of the ocean are prey for orcas. There have been reports of killer whales attacking several species of sharks off the South African coast since 2017 and the deaths were eventually linked to two killer whales in the area.
Why is Free Willy’s fin bent?
Most scientists believe that this dorsal fin collapse in captivity is due to unidirectional swimming in small shallow circles. In the wild, male orcas regularly dive deep, and swim hundreds of miles, activities which are thought to strengthen their nearly 6 foot long dorsal fins as they grow and develop.
Why do Orcas slap their tails?
Whales slap their tails to communicate with other whales and as part of their mating rituals. Whales also slap their tails to scare off predators or other males and to remove parasites and barnacles.
Why whales jump out of the water?
Yes! Scientists suspect humpback whales are breaching and slapping their fins and flukes on the surface as a way of communicating. It is believed that all slapping creates sounds used to send messages to other whales, and the big splashes are for sending messages long-distances.
What is it called when a whale slaps the water?

Commonly referred to as “pec slapping,” this is when a whale lying on it’s side repeatedly raises a long pectoral fin into the air and slams it back to the surface with a loud splash. It’s another way the whales communicate with each other.
What is the Whale movement when it raises its head above water to look around?
This act is for play, communication, or to dislodge parasites. When a humpback whale lunges forward with its head in a competitive display raised above the water, it is appropriately called a head lunge.
Do whales sleep?
Whales and dolphins are mammals and need sleep to survive, but they sleep very differently than humans and other land mammals. Humans are unconscious breathers, meaning that our bodies will automatically breathe to take in air even when we are sleeping.
