10 Best Animal Moms

If there are good dads, then here are the best animal mums.

Elephant

Ask every mother what is the hardest part of motherhood and all will be in unison in saying "giving birth is the hardest". How much more if you are to deliver a 90 kilogram baby. It's got to be a hard experience, that’s why our first mum, the female elephant, made it to the list. To add to the pain of giving birth, these mums have to endure the ordeal of a 22-month pregnancy. Baby elephant is born blind so it has to rely on her mother’s trunk for navigation. Since elephants do has a “matriarchal society” rearing a calf is not a problem for these animals. Every adult ladies in the community take turns in baby-sitting for the young ones.

Koala

We all know that koalas eat only on one thing: eucalyptus leaves (a very poisonous leaves. A female koala is equipped with a special digestive tract can endure this otherwise deadly threat, their bowels contain special bacteria that detoxify the leaves. Newly born koalas or ‘joeys' lack eyes, ears and fur and the ability to detoxify eucalyptus leaves - so they have to rely on their mums care. Koala mothers help their young ones build up their tolerance by feeding them her own feces! For purposes of information, feces are the body’s solid waste matter, composed of undigested food, bacteria, water, and bile pigments and discharged from the bowel through the anus. Joeys stay in their mother's pouch for about six months feeding on milk and forming their missing parts. While caring and nurturing their joeys, mums get about 22 hours of shut-eye a day — that’s nearly 90 percent of her life spent snoozing!

Alligator

The female alligator has a creative and ingenious way of keeping the temperature on its nest at a constant one by building it; using rotting vegetation that produces heat so it takes from her the burden of sitting on her eggs. A very nice idea, don’t you think so? Even scientists marveled at the way female alligators handled the nest temperature. If the temperature is below 31 degrees Celsius (88 degrees Fahrenheit), it’s a girl and if it tops 33 degrees Celsius (91 degrees Fahrenheit), it’s a boy! Mothers carry their newborns in their jaws for protection as well as watching and aiding them to the water, where they will spend their early years on meals such as: fish, insects, snails and crustaceans.

Polar Bear

photo link

Since male polar bears are known to be 'Macho Gigolo' – master of one -night stand; female polar bears have to suffer for the ‘quickie’ relationship. They have to put on around 180 kg (400 lb) during their pregnancy! So to sustain a normal pregnancy, prospective mums are advised to eat as much food as it could get. The reason is: if they can’t find enough food to double her weight; the poor fetus will be reabsorbed by the body. Isn’t it weird? But the good thing is; female polar bears, if ever they consumed that required diet, will have an easier time delivering the baby. All she would do is to dig a maternity den where she goes into a hibernation-like state, doesn’t eat for two months and also sleeps through the baby’s birth.

Cheetah

Mother cheetahs have a nice way of rearing up their cubs and it needs a lot of patience. For two years or more, mom has to be always there to teach, guide and protect her cubs in the rigor of daily life. Teaching them how to spot and ambush a prey at the same time protecting them from possible predators. Once the cubs learned the tricks needed to survive the hostile environment, female cheetahs leave their children to fend for themselves and moves on to start a new family.

Orang-utan

photo link

We can call female orangutan as “Mrs. Do-it-all” spending almost 90% of her life high up in the trees, building a new nest every single night. These females nurse their babies the longest amongst animal, taking care of offspring until they reach the age of 6 or 7. Also, female children often stay longer to learn child-rearing skills.

Red-Knobbed Hornbills

photo link

These small birds that are commonly found on the Indonesian island of Sulawesi make holes in trees to serve as their nests. Since monitor lizards crave for their eggs, these wily birds have to design the entryway to their nests with a very special sealant — their own feces. Can you take that? The expectant mother has to stay in the hole for two months to incubate the eggs. In so doing, ignoring hunger pains to her detriment - the smell from her protection method.

Elephant Seal

photo link

A behemoth in terms of size, the female elephant seal can weigh up to 771 kg (1,700 lb). During the pregnancy period that will take an 11-month gestation period, these moms-to-be must have to add weight each day. They don’t believe in slimming process. However, as soon as she gave birth and starts nursing her cubs, she’ll lose about 272 kg (600 lb) in less than a month.

Octopus

photo link

The female octopus doesn’t approve of birth control – she lays more than 50,000 eggs. This mum guard her eggs from predators and giving them fresh oxygen by gently blowing currents of water over them. How long will she do this? It takes 40 days for the eggs to hatch. And during this time, mum-to-be can’t hunt for food so what is her recourse? Well, having eight arms, eating one of them is no big deal. It's better to be live 7-legged octopus than a dead eight-legged creature.

Sea Louse

photo link

Small but terrible, that amply applies to our top list. This small aquatic crustacean has a cunning way of luring male into his bachelor burrow for mating – in the company with 25 other pregnant females! Poor lady, and if that wasn’t bad enough, take note – once the babies are ready to be born, they make their way into the world by eating her from the inside out.

15 Surprising Animal Facts, You Probably Don’t Know

Here is a list of some amazing animal facts that I figured you too would love – after all, we all love animals!

Hamster

Even their poor eyesight and being colorblind can’t stop hamsters in performing one remarkable feat — these stout-bodied, short-tailed cute rodents can blink one eye at a time!

Spitting Spider

photo link

The spitting spider is such a wily hunter; it has a remarkable way of catching its prey. It doesn’t wait for prey to get trapped in its web; it spits out a poisonous silk (coming from special glands in its head and abdomen) that capture the prey where it stands

Nine-banded Armadillo

The Nine-banded Armadillo (Dasypus novemcinctus), has an amazing way in producing offspring. This timid, armored animal is the only mammal that always gives birth to identical quadruplets (4 babies that come from one egg)! Imagine how many offspring can a female nine-banded armadillo in her 12–15 year lifespan.

Great Tit

photo link

The Great Tit (Parus major), which feeds mainly on insects during summer, has a clever ‘waste disposal’ scheme. This fairly large passerine bird, produces its waste in enclosed pouches that it later disposes from its nest! Believe it or not, on average, the Great tit can accumulate and remove 500 pouches of waste from its nest in a week's time.

Koala

photo link

What would a koala (Phascolarctos cinereus) gain by consuming about one kilogram of eucalyptus leaves a day? This bear-like marsupial even stock these leaves in pouches in its cheeks, Why? Eucalyptus leaves, which are 50 percent water, provide the needed liquids its body requires.

Lion

photo link

The lion (Panthera leo) enjoys a very weird sex or mating lifestyle. When the ‘King of the Jungle’ wants to mate, no fierce lioness can stop him. Copulation (desire for sexual intercourse) arises every 15 minutes for one week straight. A good thing, a lion’s sexual desire occurs only once every 2 years!

Chameleon

photo link

Many people think a chameleon changes color as a clever way to camouflage or to blend in with its surroundings. Partly true, however, this amazing ‘quick-change artist’ makes this clever act primarily to showcase some emotional state or conditions. For example: a male chameleon shows a multi-colored pattern during social displays, shows dark color patterns when angered, or lighter colors reflect light during the heat of the day. In other words, color change in chameleons occur as a social signal for communication, adapting to temperature and light, expressing mood, health condition, or simply to make them more comfortable.

Hippopotamus

Question for the day — What is the most dangerous animal in Africa? Lion-nope, crocodiles, not either, snakes-perhaps. However, records have shown that Hippopotamus (Hippopotamus amphibius) kill more human annually than the above-mentioned animals.

Diving Bell Spider

photo link

The Diving Bell Spider (Argyroneta aquatica), or water spider, is the only species of spider that live virtually its entire life under water. How does it survive? This arachnid makes such amazing feat by creating spinning a diving bell (an an open-bottomed dome-shaped silk cocoon) that acts as its living quarter, as well as ‘gills’ that take in oxygen from the water. A new study reveals, that diving bell spider can stay underwater for hours at a time.

Hedgehog

photo link

Here’s an amazing fact about hedgehog – this spiny, the little mammal that hibernate in cold climates has amazing heart rate figures to show. While resting, a hedgehog’s200 to 300 times a minute; around 150 beats a minute when sleeping and just below 14 beats per minute during hibernation.

Woodpecker

photo link

Serving both as a chisel and a crowbar, the woodpecker uses its strong, pointed beak to tear off bark in search of insects. Do you know that a woodpecker can peck its beak up to 20 times per second!

Grizzly Bear

photo link

Believe it or not, the grizzly bear (Ursus arctos horribilis), which averages between 180–360 kilograms can run as fast as an average horse! This brown bear can attain a running speed of up to 40 miles per hour.

Giant Anteater

photo link

The Giant Anteater (Myrmecophaga pterodactyl), is the largest species of anteater. An adult can measure up to 2.1 m in length with a long, tube-like head ending in a small nose about an inch wide. But do you know that these termite-eating mammals have no teeth.

Clams

photo link

‘To be or not to be’ — perhaps this is the hardest question clams are asking themselves. Why ? Because all clams are born males. However, they have the option to become a female once, and the change is irreversible

Giraffe

photo link

The giraffe (Giraffa camelopardalis), has many amazing facts to brag about. It is the world’s tallest mammal reaching 5–6 m meters in height. Also, it has the longest tail of any land mammal – up to 8 feet long, A Giraffe can open and close its nostrils at will. However, this gentle giant has no tear ducts and lacks a vocal cord!

10 Amazing Mammals Considered as Living Fossils

From a rabbit-like deer to a giraffe-like mammal, this is a list of 10 amazing mammals, scientists considered as ‘living fossils.

'Living fossils' are plants or animals that were once known to have been extinct for millions of years. But then, survived the test of time and are now found to be alive. Read on to know 10 amazing mammals, scientists consider as ‘living fossil’.

Aardvark

photo link

Aardvarks (Orycteropus afer), also called “antbears,” is endemic throughout sub-Saharan Africa. Genetically speaking, this burrowing animal resembling a pig is a living fossil, since it is the only extant representative of the order Tubulidentata. Its nearest relative is the elephant shrew. Aside from the pig-like body and a long snout, the Aardvark manifests other weird features–a kangaroo tail, a long sticky tongue and rabbit-like ears.

A solitary and nocturnal animal, it inhabits grasslands, savannahs and woodlands. It feeds mostly on ants and termites. Sporting a thin Yellowish/Gray/ Brown coat, adult ones measure between 109 to 135 cm in body length , around 50 to 82 kg in weight and about and 53 to 66 cm tall. Aardvark can live up to 23 years in captivity.

Amami Rabbit

The only species in its genus, the Amami Rabbit(Pentalagus furnessi), also called as the Ryukyu Rabbit, is found only in Amami Ìshima and Toku-no-Shima, two small islands of Japan. This primitive dark-furred rabbit, called a living fossil, because its physical characteristics resemble those of prehistoric rabbits living during the Miocene age.

The Amami Rabbit has a bulky body, small eyes and ears, short limbs, a long snout and large, curved claws. This forest-dweller has dense and wooly fur that is dark-brown in color, mark with reddish-brown underbelly. It measures between 430-510 mm long and around 2 kg in weight. The Amami Rabbit’s diet includes berries, bamboo shoots, acorn, leaves and stem of sweet potatoes. As a result of rampant hunting, this ancient rabbit is Classified as Endangered on the 2010 IUCN Red List of Threatened Species.

Chevrotain

Chevrotain, also called mouse deer, is any of 10 extant species of small, hoofed mammals found in Africa and SE Asia. These living fossils of primitive ruminant mammals are classified under the family Tragulidae (order Artiodactyla). All species lack horns, but have strong upper canine teeth. They sport reddish-brown coat mark with white spots. Depending on the species, chevrotains measure between 20 -50 cm at the shoulder, and weigh between 0.7-16 kg.

They have rabbit-like body, arched back and very slender legs. They are solitary and nocturnal mammals that feed on leaves, twigs and fruits of plants. However, the African water chevrotain (Hyemoschus aquaticus), occasionally feed on insects, crabs, and fish.

Elephant shrew

Elephant shrews, also called jumping shrews, are small mouse-like mammals indigenous to Africa, comprising the family Macroscelididae, in the order Macroscelidea. These living fossils are not related to the true shrew and recent studies suggests that they are more related to golden moles, aadvarks, hydraxes and elephants. These primitive mammals have elephant-like long noses and the trunk, large canine teeth, long legs and short mouse-like tails.

Elephant shrews measure between 10-30 cm and weigh from 50-500 g, depending on the species. Colors vary from brown to gray to a combination of the two. The Elephant shrews diet includes: insects, earthworm, spiders, centipedes, and millipedes. Some species also consume leaves, fruits and seeds.

Koala

The Koala (Phascolarctos cinereus)is a cute and amazing mammal native to Australia, and the only living species of the family Phascolarctidae. These herbivorous marsupials might have originated from wombat-like animals (its closest living relative). These arboreal and placid bear-like animals are active only for 3-5 hours a day, which they mostly used feeding on eucalyptus leaves.

Koala has a flat nose, big ears and ash-grey thick furred coat, with white markings on the chest. Koalas of the southern regions which are larger than the northern ones average 78 cm (males) and 8 kg (males). Koalas can live between 13-18 years.

Iriomote cat

The Iriomote cat (Prionailurus iriomotensis), is a wild cat considered a “living fossil” that is only found on the Japanese island of Iriomote. Discovered in 1965, this endangered species of cat have dark brown fur with dark stripes around the neck, elongated body, short legs and a bushy tail. A solitary but excellent hunter, it measures 48 cm in body length, 25 cm at shoulder height and weighs between 3–7 kg. It feeds on rats, bats, snakes, birds, lizards, frogs and insects. With barely 100 individuals left, the Iriomote cat is listed as Critically Endangered by The International Union for the Conservation of Nature and Natural Resources (IUCN).

Monito del Monte

photo link

Regarded by scientists as a living fossil, the Monito del Monte (Dromiciops gliroides) or “mountain monkey”, a small marsupial is the only surviving representative of the superorder Australidelphia. A nocturnal and arboreal mammal, it is widespread across Argentina and Chile inhabiting dense, cool, humid forests. Slightly larger than a mouse, it measures between 83-130mm (head to body) length, around 90-132 mm tall and weighs between 16-42 g.

It has dense, silky brown-colored fur, short and furry ears, round eyes mark by black rings and a hairy prehensile tail. An amazing and excellent tree climber, it feeds mainly on insects and other small invertebrates. The Monito del Monte has a life span of about 2 years. Its population decreasing due to habitat loss, this marsupial is Listed as Vulnerable on the 2006 IUCN Red List of Threatened Species.

Okapi

The okapi (Okapia johnstoni), is another amazing ’living fossil’, resembling a zebra, but is more closely related to the giraffe. Currently numbering about 10,000–20,000 in the wild, Okapis are native to the Ituri Rainforest, in the Democratic Republic of the Congo, in Central Africa. On average, they measure between 1.9 – 2.5 m long, stand 1.5 – 2.0 m at the shoulder and weigh between 200 – 300 kilograms.

These giraffe-like mammals have reddish-brown coat mark with horizontal white stripes on their legs. They have large ears and a 14 inch bluish grey tongue. A solitary, diurnal mammal, okapis feed on tree leaves and shoots, fruits, ferns and grass.

Red Panda

photo link

The red panda (Ailurus fulgens), the only living representative of the genus Ailurus, is a small tree-dwelling mammal found in China, Myanmar, Nepal, and Bhutan. Red panda is just about the size of a domestic cat, measuring between 50 to 65 cm in head to body length, and weighing around 5.4 to 9 kg.

It has soft reddish-brown fur, a cat-like whiskers, and a hairy tail reaching 30 to 50 cm long. A shy, solitary but excellent tree climber, it feeds mainly on bamboos but may also consume insects, birds, eggs, and other small mammals. Its population declining cause by habitat loss and poaching, the red panda is now endangered.

Giant Panda

The giant panda (Ailuropoda melanoleuca), is a bear native to central China, which inhabits high altitude bamboo-rich coniferous forests. These amazing ‘living fossils’ can easily be recognized by the large, unique black patches surrounding the eyes and across its round body. A terrestrial animal, it feed primarily on bamboos and occasionally wild tubers and grasses.

Adult pandas measure between 1.2 to 1.8 m long, around 75 cm tall at the shoulder, and can weigh up to 150 kilograms. The tail can measure 10 to 15 centimeters. In the wild, pandas can live up 20 years and up to 30 years in captivity. Due to habitat loss and other development, the panda is now an endangered species
