Our culture is fascinated by the biggest and the best of anything. Fast food restaurants have recognized this for years, which is why they sell a Whopper, Quarter Pounder, or a Big Mac, all things signifying that it is massive. So it only seems fitting that we would also find the largest animals fascinating.

What Is the Biggest Animal in the World?

The Blue Whale

The Blue Whale is the largest animal averaging 110 feet or 22 meters long, weighing 209 tons. The blue whale is believed to be the largest animal ever existed, beating out even the most giant dinosaur.

It has a blowhole at the top of its body. It raises its blowhole further out of the water than any other whale when it breathes. They are fast as well, traveling 31 miles per hour, equal to 50 kilometers.

Despite its massive size, the whale has a narrow throat- narrow compared to its body. It can only swallow something smaller than a beach ball. Despite the tiny throat, its mouth can hold up to 90 metric tons of food and water.

At birth, they weigh equal to a grown hippopotamus at around 6000 pounds, about 2700 kilograms. For the first several months of a whale's life, it needs 100 gallons of milk a day to survive.

What is the Longest Animal?

Longest Animal - Arctic Lion's Mane Jellyfish

A Lion's Mane Jellyfish is the most giant jellyfish known to humankind.
It is also the longest animal at 200 feet long. Its bell can reach eight feet across, equal to 2.5 kilometers. Despite its long tentacles, it's usually not a deadly sting, although very painful.

They usually stay relatively close to the surface. The deepest it often ventures is around 20 meters deep. They can travel great distances due to the ocean currents and can pulsate to move forward.

Its size primarily determines the color of a Lion's Mane Jellyfish. Larger Lion's Mane Jellyfish will be a dark purple, whereas smaller ones will have more of an orange tint to their body.

What is the Largest Egg?

An Ostrich Egg

Once an ostrich is around two to four years old, it will begin laying fertilized eggs in a nest, a pit that is one to two feet deep and 9.8 feet wide. It is a communal nest that numerous female ostriches use, and the dominant ostrich lays her eggs first. If there are is an abundance of eggs, she will discard eggs from the weaker ostriches.

Although the eggs are the largest bird eggs, they are the smallest eggs compared to the bird's body. The incubation period is around 35-45 days long. The egg is usually 5.9 inches long and 5.1 inches wide, and about 3.1 pounds.

The Giant Clam

Giant Clams can measure longer than four feet across and weigh more than 441 pounds or 200 kilograms. The largest giant clam that has ever been found was measured as 53.9 inches, equal to 137 centimeters. It was discovered in Sumatra in 1817 and weighed 734 pounds, which is equivalent to 250 kilometers. A Northern Ireland museum has this giant clam on display.

The development is a fascinating part of a giant shell. After they lay an egg, the egg floats in the water for twelve hours until it hatches, at which time the larva will develop a chalk shell. Soon it will grow a "foot" that allows it to travel across the bottom of the sea. It can search for a habitat that is best suited for it. Most young clams die soon after this stage. However, some giant clams live as long as 100 years old or more in the wild.

What Land Animal Has the Largest Mouth?

Hippopotamus

Although the Savanna Elephant beats out the hippopotamus as the largest land animal, it does have the most immense mouth of any land animal. The mouth can open a full 180 degrees! They usually only open their mouths when they are feeling threatened.

Hippos are semi-aquatic. The adult hippo can spend up to 3-5 minutes underwater before they need to come up to take a breath. Young ones may need to take a breath as soon as two minutes of being underwater. Although they do not need to be awake to come out of the water, hippos can fall asleep underwater and come up to breathe without waking. They are incredibly aggressive, and are the third-largest land animal, beat out by both the elephant and the rhinoceros.

Largest Land Animal: The Savanna Elephant

The Savanna elephants are the most giant elephants, as well as the largest land animal on earth. They are one of the two types of African elephants. All African elephants have concave backs as well as ears that are generally larger than Asian elephants. The males are bigger than females. For instance, the male usually is between 10 and 13 feet high measured at the shoulders. They typically weigh between 7,700 and 26,000 pounds. The female is smaller at about 9.8 feet tall.

In 1965, the largest Savanna Elephant was shot in Angola. He weighed 27,060 pounds and standing 13.8 feet high and weighed 8 tons, where his remains rest at Washington, DC, in the National Museum of Natural History. For its large size, you can imagine it has a very hefty diet. It requires at least 190 liters of water every day and eats 225 kilograms of vegetation, which it never adequately digests.

What is the Largest Bat?

Giant Golden-crowned Flying Fox

The Giant Golden-crowned Flying Fox wins the title of being the largest bat in the world with a wingspan of 5 feet or 1.5 meters! They are named because their face looks much like a fox!

They mainly live in rainforests and caves in the Philipines. They are endangered animal and is extremely close to extinction due to poachers. They are shy animals and do not live in areas where humans have inhabited. As more regions become inhabited by people, fewer places are available for the flying fox to live.

Actually yes, the Pygmy Marmoset! You can read about it in the article: https://owlcation.com/stem/Worlds-Smallest-Animals

does any one now about the littest monkey

Angela Michelle Schultz (author) from United States on May 16, 2010:

Yes, I found that really interesting about the ostrich egg! Actually I found all these facts interesting, hence the hub! There are more facts planned for both hubs, but I have to first find good photos to go with them. :)

Ultimate Hubber on May 16, 2010:

Although you published this one first, but I have read the one about smallest creatures before this. Both these hubs are lovely!

And like you said, ostrich's eggs are the smallest of all birds. Smallest eggs in proportion to the mother's body weight.

Thanks Cheeky Girl! Nature really is amazing. I think the one that surprised me most was the blue whale. I knew they were the biggest, but when I started putting them in perspective, especially when I realized that they were bigger than any dinosaur! I was like wow!

Cassandra Mantis from UK and Nerujenia on May 13, 2010:

Aw, I really liked this hub! I love animals! Elephants and Hippos especially! I didn't know whale sharks grew so big. These are truly large animals. nature is so amazing! Cheers!

Angela Michelle Schultz (author) from United States on May 11, 2010:

Pamela, Thank you so much. I was trying to find facts that I didn't know before. Some of them were harder to find information than others. :)

Angela Michelle Schultz (author) from United States on May 11, 2010:

Garnetbird, I know I've told you this before, but I'm fascinated by your husbands job. I actually was thinking about writing a hub on the Wholly Mammoth.

Pamela Oglesby from Sunny Florida on May 11, 2010:

I really liked this hub as it was so interesting and had so many little facts about the various animals. Great hub.

Gloria Siess from Wrightwood, California on May 10, 2010:

Excellent work. My ex-Husband uncovered a Wholly Mammoth in Holmes County, Ohio. It was HUGE!

Angela Michelle Schultz (author) from United States on May 10, 2010:

Thanks BkCreative! Awesome, thanks for rating it up. This is one big obsession that I think is completely healthy. I couldn't believe that Hippopotamus' can open their mouth 180 degrees. I would love to see that. It's like their mouth is on a hinge. I'm curious if there are any snakes that can. I imagine that there are.

BkCreative from Brooklyn, New York City on May 10, 2010:

Love this big hub! I am a hippo lover myself - and am so proud to know they have the biggest mouth - I have looked into many.

We do love big here in the US - but it's big junk. No quality - just big has become the selling point. Ah, but the animals of the earth are big and beautiful.

What a fun and unique hub - and thanks so much for finding a way to include the marvelous hippo! Rated up, of course!
