10 Amazing Animal Facts

Crocodiles Eat Stones

The stomach of a crocodile is a rocky place to be, for more than one reason. To begin with, a croc’s digestive system encounters everything from turtles, fish and birds to giraffes, buffaloes, lions and even other crocodiles

Whale Milk is 50% Fat

Nursing a newborn is no “small” feat for the whale, whose calf emerges, after 10 to 12 months in the womb, about a third the mother’s length (that’s a 30-foot baby for the Blue whale).

Beavers have Longer Days in Winter

Beavers become near shut-ins during winter, living off of previously stored food or the deposits of fat in their distinctive tails. They conserve energy by avoiding the cold outdoors, opting instead to remain in dark lodgings inside their pile of wood and mud.

Birds Recognize Landmarks

Can you imagine a road trip vacation without missed exits, stubborn drivers or map-folding disasters? Of course noteyou’re not a bird. Pigeons can fly thousands of miles to find the same roosting spot with no navigational difficulties.

Mole-Rats are not Blind

With their puny eyes and underground lifestyle, African mole-rats have long been considered the Mr. Magoos of rodents, detecting little light and, it has been suggested, using their eyes more for sensing changes in air currents than for actual vision.

Baby Chicks are Altruistic

It’s a mistake to think of evolution as producing selfish animals concerned only with their own survival. Altruism abounds in cases where a helping hand will encourage the survival of genetic material similar to one’s own.

Many Fish Swap Sex Organs

With so many land creatures to wonder at, it’s easy to forget that some of the weirdest activities take place deep in the ocean. The strange practice of hermaphroditism is more common among species of fish than within any other group of vertebrates.

Giraffes have Unique Blood Flow

The stately giraffe, whose head sits some 16 feet up atop an unlikely pedestal, adapted his long neck to compete for foliage with other grazers. While the advantage of reach is obvious, some difficulties arise at such a height.

Elephants are Smart

Elephants have the largest brain, nearly 11 pounds on average of any mammal that ever walked the earth. The average elephant EQ is 1.88. (Humans range from 7.33 to 7.69, chimpanzees average 2.45, pigs 0.27.)

Parrots Understand

Parrot speech is commonly regarded as the brainless squawking of a feathered voice recorder. But studies over the past 30 years continually show that parrots engage in much more than mere mimicry.
