What is the biggest sea creature that ever lived?
#1—Blue Whale
Not only is the blue whale the largest animal to live on the Earth today, they are also the largest animal to have ever existed on Earth. A blue whale can grow up to 100 feet long and weigh upwards of 200 tons.
Was the mosasaurus the biggest dinosaur?
That said, the real Mosasaurus was indeed a large animal, with the biggest specimen known estimated to be around 17 meters or 56 feet long (Grigoriev, 2014). This makes it one of the largest, if not the largest, members of the mosasaurid family alongside other big species like the 14 meter North American Tylosaurus.
Is a mosasaurus a real dinosaur?
Mosasaurs ARE NOT DINOSAURS. They are reptiles and are closely related to snakes and monitor lizards. Mosasaurs went extinct at the end of the Cretaceous during the end Cretaceous mass extinction event. The Tylosaurus mosasaur shown on the Jurassic Park movie was the largest mosasaur to exist.
What was bigger than the Megalodon?
When it comes to size, the blue whale dwarfs even the largest megalodon estimates. It’s believed blue whales can reach a maximum length of 110 feet (34 meters) and weigh up to 200 tons (400,000 pounds!).
Is any animal bigger than the blue whale?
While there might never be a larger animal than the blue whale, there are other kinds of organism that dwarf it. The largest of them all, dubbed the “humongous fungus”, is a honey mushroom (Armillaria ostoyae).
Can a mosasaurus kill a Megalodon?
While a similar length, the Megalodon had a much more robust body and huge jaws built for devouring whales and other large marine mammals. A Mosasaurus would not have been able to get its jaws around the much thicker body of the Megalodon. It would just take one catastrophic bite for the Megalodon to end the battle.

The Mosasaur Size Chart says that Mosasaurus is the largest mosasaur (like how I think), and compared to the T-Rex size, Mosasaurus is definitely bigger than both I-Rex and T-Rex. … I think that it reached 16-18 meters (That’s about 55-60 feet, bigger than Spinosaurus, I-Rex, and T-Rex.)
What killed the mosasaurus?
During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators. They became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago.
Is mosasaurus bigger than Blue Whale?
The largest estimates for Mosasaurus hoffmani put it at around 56 feet in length, about half the size of the largest blue whales on record. There’s no precedent for any predator alive being able to hunt down whales that size, but there aren’t many predators the size of a Mosasaurus either.
Are ichthyosaurs Diapsids?
Ichthyosaurs are superficially dolphin-like reptiles that were important marine predators from the Triassic Period through the middle of the Cretaceous Period. … For now, paleontologists think that ichthyosaurs are diapsids, but exactly where they fit in the diapsid tree is not yet known.

No, the blue whale is much bigger. Megalodon was up to 60 feet long, while blue whales are 80 to 100 feet long. Though extinct, a mature male Megalodon is estimated to have had a mass of about 80,000 lbs., The Blue Whale, with an adult mass of 110,000 – 330,000 lbs, would be significantly larger.
What hunted Megalodon?
Mature megalodons likely did not have any predators, but newly birthed and juvenile individuals may have been vulnerable to other large predatory sharks, such as great hammerhead sharks (Sphyrna mokarran), whose ranges and nurseries are thought to have overlapped with those of megalodon from the end of the Miocene and …
