What is the largest pet fish?

What is the biggest whale shark ever caught?

There is a lot of uncertainty as to the size of the largest specimen of whale shark ever caught due to the variety of methods used to measure the caught specimens. In 1868, an Irish scientist E.P. Wright claimed to have observed whale sharks that were over 50 ft long.

What is the maximum height of a blue whale?

Hydrodynamic models suggest a blue whale could not exceed 108 ft (33 m) because of metabolic and energy constraints. The highest recorded weight for the species is 199 tonnes (196 long tons; 219 short tons).

What is the biggest animal on the Earth?

The biggest animal on the Earth is the adult blue whale. These animals are bigger than any dinosaur that’s ever lived, and they are far bigger than the largest living land animal on the planet today. Blue whales can grow up to 105 feet long (32 m).

Is a cartilaginous fish related to a bony fish?

The cartilaginous fish are not directly related to the “bony fish,” but are sometimes lumped together for simplicity in description. The largest living cartilaginous fish, of the order Orectolobiformes, is the whale shark ( Rhincodon typus ), of the world’s tropical oceans.

What is the largest known fish?

The largest known fishes of the now-extinct class Placodermi were Dunkleosteus and Titanichthys. These particular animals may have reached lengths of 10 m (33 ft) and are estimated to have weighed 3.6 tons. The cartilaginous fish are not directly related to the “bony fish,” but are sometimes lumped together for simplicity in description.

What is the average size of a whale?

The typical Blue Whale has an overall height of 13’-16’ (3.96-4.88 m) and body length of 82’-105’ (25-32 m). An average Blue Whale weighs between 55-165 tons (50-150 metric tons) and has a typical lifespan of 80-90 years.

Why are blue whales getting bigger?

One hypothesis is that as blue whale populations recover from whaling, this is increasing sexual selection pressure (i.e., a lower frequency indicates a larger body size).

How big is a blue whale in meters?

The typical Blue Whale has an overall height of 13′-16′ (3.96-4.88 m) and body length of 82′-105′ (25-32 m). An average Blue Whale weighs between 55-165 tons (50-150 metric tons) and has a typical lifespan of 80-90 years. Consequently, what is bigger than a blue whale?

How big is a megalodon compared to a blue whale?

But they’re still not quite as large as a blue whale. The largest megalodon ever would be estimated to be around 250,000 pounds. The smallest adult blue whale usually averages around 290,000 pounds. Getting a true comparison with such large numbers can be difficult though.

How big is the tail of a blue whale compared to humans?

It’s easy to forget just how big a blue whale is compared to a human until you learn that just the tail of a blue whale is 25 feet wide – nearly 5 times the height of an average human!

Is the blue whale trapped in a circle of specialization?

“ [The blue whale has found itself] trapped within a tautological circle of specialization: it needs to be big enough in order to eat enough to be big. […] Ecological entrenchment has become entrapment.” Where will the increase in size stop?

Why don’t toothed whales evolve body sizes greater than sperm whales?

Because of a lack of large enough prey, we found that toothed whales’ energetic efficiency decreases with body size – the opposite of the pattern we documented for baleen whales. Therefore, we think the ecological limits imposed by a lack of giant squid prey prevented toothed whales from evolving body sizes greater than sperm whales.

Why is the blue whale so big?

Additionally, to effectively hunt krill and properly nourish its huge body, the blue whale compensates for the lack of agility with an even bigger mouth, and therefore an even bigger body. “ [The blue whale has found itself] trapped within a tautological circle of specialization: it needs to be big enough in order to eat enough to be big.

Do whales benefit from being big or small?

Writing in Science this week, they say baleen whales, who become more energy-efficient as they grow, benefit from bigness because it lets them migrate to food sources that appear and disappear at different points around the globe. Meanwhile, they say, deep-diving toothed whales are limited by the availability of large prey.

How big is a megalodon shark compared to a whale?

However, scientists estimate that the Megalodon shark was around 60 feet or 18 meters long. As the biggest whale in the world, the average blue whale can grow to be anywhere from 90 to 100 feet long, trumping the size of Megalodons and other marine mammals. Even the tongue of a blue whale weighs the same as an adult elephant!

Can a megalodon kill a blue whale?

Megalodon was potentially capable of taking on Blue Whales, but it is doubtful they’d go for something so large and tedious to kill, especially something 40 feet longer and far heavier, sort of like a lion going after an elephant. Besides, there was probably far better, far smaller whales to eat. How big was a Megalodon compared to a whale?

What are some interesting facts about the Megalodon?

The Megalodon holds the unique reputation of being not only the largest prehistoric shark ever, but it was also the biggest marine predator on earth. It was so big that it outweighed the Great White Shark and reptiles such as the Kronosaurus and Liopleurodon. Here a few other interesting facts about this unique creature: 1. They fed on Giant Whales

Are blue whales bigger than dinosaurs?

The coolest things about Blue whales are that not even the largest of dinosaurs have been recorded as being larger than it. As we pointed out earlier, not even the biggest Megalodon was recorded as being larger than a blue whale. The average blue whale is recorder to hit lengths of about 90 feet and 100 feet long.

How has the blue whale become trapped?

And this is how blue whale has become trapped within a tautological circle of specialization: it needs to be big enough in order to eat enough to be big. The means and the end have become one and the same. Ecological entrenchment has become entrapment. The only way to get out, somehow, is to get bigger.

How big is a blue whale compared to other animals?

And it weighs roughly 25 times more than the largest living land animal, the elephant. In terms of size, the blue whale is unmatched. Even the fin whale, the second largest animal on the planet, weighs only about half as much. Such dimensions inevitably raise the question: what drove the blue whale to the path of gigantism?

Why do blue whales need to be so big?

Bigness is key to the blue whale’s diet, but bigness also adds to the whale’s overall energy budget. A bigger body requires more food, which even fewer portions of the world ocean can support, thus requiring a bigger body that can travel even further with larger energy stores and greater efficiency.

How did whales become so big?

This ripple effect quickly led whales on the path to gigantism. But for this feeding technique to pay off, the necessary resources had to be available. This is why the size of whales did not really plateau until the advent of the last ice age, some 5 million years ago.
