The Megalodon weighs in at upwards of 50-70 tons, measuring a span of up to 60-70 feet in length. By contrast, the Blue Whale tips the scale at around 100-110 tons and tops lengths of up to 100 feet. Who Wins on Size? It's pretty obvious that the Blue Whale is the bigger apex predator in this fight.
Megalodon, an ancient shark, had such a huge appetite that it could have swallowed an 8-metre-long whale in just a few bites, according to the first 3D reconstruction of the predator. This new description upgrades its already gigantic size to at least 16 metres long and a weight of 61.5 tonnes.
A megalodon is much larger than a whale shark, weighing 50 tons and growing about 60 feet or more throughout its lifespan. The whale shark is a massive animal in its own right, weighing between 15 and 20 tons and growing up to 40 feet in length! Megalodon has a serious advantage in terms of size in this case.
These sharks were huge. A killer whale is one of the largest creatures in the ocean, although they aren't individually as large as megalodon. On average, an orca weighs between 6,600 and 8,800 pounds, or about 1/27th the size of megalodon.
Is the megalodon still alive? 'No. It's definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,' notes Emma. 'If an animal as big as megalodon still lived in the oceans we would know about it.'
Megalodons succumbed to global cooling due to the shrinking of their habitat, the vanishing of their favorite prey, and competition from other predators 3.5 million years ago.
Some larger estimates do exist (placing megalodon up to 67 feet in length and well beyond 50 tons), but the fact of the matter is megalodon was smaller than a blue whale. In terms of size, a blue whale gets the advantage. Blue whales are larger and heavier than a megalodon.
The biggest shark in the world is the whale shark
Though there are some reports of larger individuals, the biggest specimen ever reliably measured was 18.8 metres or nearly 62 feet long! That's bigger than a school bus! Even though they're enormous, whale sharks pose no danger to humans.
Past megalodon research suggests these giant marine predators, which first appeared around 16 million years ago, could chomp with more than three times the force of T. rex, based on the new figures. The bite force of a megalodon—"just because it was so much larger-bodied—would have been bigger," Bates said.
Share: Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived. An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg - that's about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons. Their tongues alone can weigh as much as an elephant.
A Livyatan would win a fight against a megalodon. The Livyatan has the size and speed advantage, bigger teeth, and it has endurance to last through a long fight.
In addition to being the world's largest fish, megalodon may have been the largest marine predator that has ever lived. (Basilosaurids and pliosaurs may have been just as large.) Megalodon was an apex predator, or top carnivore, in the marine environments it inhabited (see also keystone species).
The mythical kraken may be the largest sea monster ever imagined. Some stories described it as more than 2.5 kilometers (1.5 miles) around with arms as large as ship's masts.
1. Great White Shark. Great white sharks are the most aggressive sharks in the world has recorded 333 attacks on humans, with 52 of them being fatal. The inclusion of this particular species probably comes as no surprise since movies, particularly Jaws, and television shows are quick to show their aggression.
Great White Shark (Carcharodon carcharias) 20 feet / 6.1 m
The greatest predator on Earth, the great white is famous worldwide for hunting ability.
While Deep Blue may be one of the largest fish in the ocean, these creatures can still be elusive and NOAA estimates a great white shark lifespan to be around 30-70 years so there's every chance Deep Blue is still alive and well in the ocean to this day.
The extinct superpredator megalodon was big enough to eat orcas, scientists say | CNN.
While we think of most whales as docile, these beasts were a notable exception, being apex predators who would aggressively pursue any potential prey in their environment, megalodons being among them.
The battle for diminishing stocks of whales and other prey may have pushed the megalodon to extinction three million years ago. Environmental pressures, such as sea level changes, also played a role. The extinction of the megalodon has been an enduring mystery.
Some megalodons are estimated to have been much larger―as long as 50 feet. Using the data from this study, together with previous research, the researchers concluded that the potential lifespan of megalodons was 88-100 years.
