Blue whales are the largest animals ever to exist, EVER. Find out more about these amazing creatures

Blue whales are incredibly, incredibly large. Measuring 100 ft long and weighing in at 190 tons, blue whales are the largest known creatures to exist, ever. Even the largest known dinosaur Argentinosaurus only clocked in at 99 tons—a little more than half the size of a full grown blue whale!

The feeding habits of blue whale are equally massive. Blue whales feed primarily on a small zooplankton known as krill, which are individually quite tiny. That means that in order to eat the almost 8,000 lbs of krill they need on a daily basis to survive, they can eat in excess of 40 million krill every day.

Because of their massive size, many of their individual organs are some of the largest in the animal kingdom as well. A blue whale's tongue can clock in at more than 3 tons, making it about the same weight as your typical minivan.

Adolescent blue whales are equally impressive. Able to drink in excess of 100 gallons of milk a day, growing whales gain 200 lb every 24 hours on average. Even when they're born, a baby blue whale weighs almost as much as a fully grown hippo!


Manatees have fingernails! Here are 5 more amazing facts about the manatee

Yes, that's right. Manatees, also known as sea cows, really do have fingernails.

They are large aquatic mammals, and therefore have the same internal bone structure as other mammals, very similar to that of humans.

The eyes of manatees don't blink up-and-down like ours, though. They actually open and close in a radial motion, similar to that of a camera shutter!

A manatee tail is called a paddle, unlike the split fluke of a dolphin or whale. However, they use them to move in the same way, moving them up and down to locomote.

Manatees can also hear just like us. Although they don't have external ears like many other mammals, as aquatic animals, they don't need them. Instead, they have small pinholes on the side of their head that let in vibrations in the water that they then translate into sound.


Bald Eagle talons are huge! But the best thing might be that they're no longer an endangered species

The bald eagle is the national bird of the United States, but for a long time we were in serious danger of wiping them out completely. As of 2007, they are now in the category "of least concern", but you won't believe just how close we came to never seeing another one.

In 1963, there were a low of only 413 breeding pairs of bald eagles—and even then, there was no guarantee that those breeding pairs would successfully have offspring. The problem lied in the pesticide DDT.

DDT was used in an incredibly widespread way following WWII. However, an unexpected side effect of the use of DDT was that it thinned the shells of birds of all kinds, eagles especially. So, when nesting mothers would sit on the their eggs, they would crush them—completely decimating the population.

Thankfully, the government banned the use of DDT in 1972, and by 2007, the population of eagles grew to almost 50,000 birds!


Some awesome lists!

No one in Australia has died from a Spider bite since 1981!

Australia is very famous because of it's dangerous animals that can be found throughout the country.

They do have a lot of dangerous and poisonous animals; however most of them are easily avoided with a little common sense. Most do not live in cities, and types of animals vary depending on which part of Australia you go to.

Remember that Australia is a huge country; they have variations in climate and habitat. They also do get snow in many places each winter. Anyway, most of Australians manage to live there relatively incident-free.

For instance, no one has died from a Spider bite ever since 1981! Ever since anti-venoms were introduced, the fatality rate has diminished to practically zero.


Romans thought Giraffes were hybrids between camels and leopards. This one ate everything he could reach!

Back in the days before widespread communication through the internet or even the printing press, people's understanding of animals that were not native to their area was spotty at best. The friendly giraffe was perhaps one of the most misunderstood animals of those times.

Ancient Greeks and Romans thought that the giraffe was the result of an "unnatural" paring between a camel and a leopard, going so far as to call it a "camelopardalis". That didn't stop them from collecting them during their forays into northern Africa.

In their native Africa, the giraffe was the subject of many folk tales and legends about how it got so tall. One tells the story of a giraffe with a regular sized neck eating too many magic herbs and growing to a dramatic height.

Later on in history, captive giraffes made quite a stir at many of the world's royal courts. The powerful Medicis in Florence once received one as a gift. Unfortunately, that giraffe died quickly in captivity when it caught it's neck in the beams of the horse stables it was kept in. By 1414, a giraffe had made it's way all the way to China, where it was revered as a form of Qilin, a Chinese good omen often referred to as "The Unicorn of China".
