Awesome science facts for kids

I have a keen interested on and just want to share this amazing information about to all of you: Little-known facts about Laos

• Porpoises are among the smallest aquatic mammals. Check out my list of fun, weird and just plain amazing fact of life I have found.
• They are related to dolphins and whales and belong to the same order, Cetacea.
• They are very similar looking to the dolphin. However, the way to distinguish them generally is from: their smaller size; they have a rounder body shape and they lack the ‘beak’ of the better known dolphins.
• There are six species of porpoise.
• Different types of porpoises include the Common or Harbour porpoise, which is dark coloured on back and white underside, for camouflage in coastal waters and is similar to the Californian porpoise; Dall’s porpoise, which has a slightly more muscular body, they are jet black on back with white patches on the belly and flanks; Burmeister’s porpoise, which is dark overall, the Dorsall (back) fin has a sharp point with ‘teeth’ on its leading edge; Finless porpoise, which are grey overall, except for paler throat and face, they have a rounded, blunt head and no dorsal fin; the Spectacled porpoise, which is blue-black on back and white on sides and under-parts, they have a rim around their eyes which resemble spectacles. That might be one of the most awesome interesting facts ever.
• Porpoises are thought to have emerged as a group of aquatic mammals about 15 million years ago, when they were confined to the north of the Pacific Basin. From these beginnings they slowly evolved into the total of six species of porpoise alive today.
• They are sociable creatures and are often found in groups of 2-20, but usually about 4.
• They are sexually mature by the age of 4-7 years, according to the species. mating season is summer in the northern hemisphere. Gestation is 11-12 months and they have 1 young.
• Young calfs are born half the length of the female and has to be brought to the surface immediately to take its first breath. The female often swims on her side as she suckles her young calf. In this way they reach the water’s surface to breathe at the same time. This only happens in the first few days after birth, and soon the calf surfaces independently and dives to resume feeding. The young often remain with its mothers after being weaned.
• The Dall’s porpoise is known to be the fastest of all the porpoises. It powers through the water at speeds of 20-30km/h. It is also famous for its ‘rooster’ spray – a stream of water that arcs up over the head as it reaches the water’s surface. They are the most sociable and are attracted to moving ships.

• The Finless porpoise, as its name suggests, has no dorsal fin. The females have been known to carry her single young, or calf, on her back as on a saddle.
• Porpoises have between 60-120 teeth which are flattened into a spade shape at the tip.
• The common porpoise makes a distinctive, explosive noise as it comes to the surface to exhale. It has also been called a ‘puffin pig.
• Similar to the dolphin, the porpoise have a wide repertoire of communication calls, including ‘clicks’ used for echo-location. That might be one of the most awesome animals facts you had no idea before.
• Their greatest threat to population is fishing nets and pollution. Some species are thought to be declining as a result. 
• Another hazard of inhabiting coastal waters for the common porpoise is that it can get stranded on beaches.

1. MOOSE ARE HUGE.

Moose are the largest members of the deer family, weighing as much as 1200 pounds; they can grow to be 5 to 6.5 feet from hooves to shoulders. This does not include a raised head or antlers, so it's safe to say that the majority of moose tower over all non-basketball players.

2. THEY EAT A LOT.

With huge size comes a huge appetite. Moose are browsers and will casually devour 73 pounds a day in the summer and 34 pounds in the winter. They eat an assortment of shrubs, woody plants, and aquatic vegetation; in the winter, their diet is more restricted, so they eat the buds of plants.

3. ORGANISMS OF ALL SIZES POSE A THREAT TO MOOSE.

Moose are formidable opponents with sharp hooves that can kick with tremendous force, but even they have predators. A pack of wolves or a black bear is no match for a healthy adult moose, so bears and wolves typically pick off the young, sick, and old. And even though moose are powerful and quite large, a single bite can do one in: There's a good chance the bite will cause an infection that eventually kills the animal up to two weeks later. 

Moose also have a much smaller menace to worry about: parasites. Brain worm (Parelaphostrongylus tenuis) is a parasite contracted from eating snails. The infectious larvae migrate to the moose's brain and cause neurological damage. "It’s interesting thinking of something as big as a human hair killing a 1200 pound moose, but they do," Carstensen says. 

Another tiny nuisance is the winter tick. Tick infestations depend on the weather and habitat: Harsh winters mean less ticks the following year; when ticks fall off animals to complete their cycle and there's still snow on the ground, they die. So hard, long winters are great news for moose. 

4. THEIR ANTLERS ARE USED FOR FIGHTING...

When fighting off predators, the antlers, or paddles, don't come into play as much as you would think; a moose's first line of defense is its sharp hooves, which are capable of mortally wounding a wolf or bear.

Paddles are only found on males, and used mainly for fighting and displaying. During mating season in autumn, bulls will cover a lot of ground looking for females to mate with. They establish breeding territory by fighting off other males in the area. The fights are not always fight-to-the-death scenarios, and often a competing moose will back away from a fight if the challenger has a more impressive rack of antlers. Great paddles are not the only way to find mates; some males with better navigational skills—or just sheer luck—may come across a female by chance and completely skip antler combat. 

5. ...AND THEY SHED EVERY YEAR.

Moose lose their paddles every winter and grow new ones the following spring. "Antler growth is based on testosterone levels and day length," Carstensen says. "So they start to grow those antlers in the late spring and summer, and they’re covered in velvet. The velvet is vascularized so there is a blood-flow supplying these antlers as they’re growing." By early fall—a.k.a. mating season—bulls start to shed and shine their paddles by rubbing them against trees. Their fuzzy velvet-covered antlers go through a gory transformation, and by October they will have shiny new paddles for competition and display. 

Antlers are also a great indicator of age. With each winter, young moose paddles grow in size: nubs become spikes and spikes become full racks. Bulls in their prime, between ages 5 and 8, have the largest racks. With old age, the antlers become more deformed and less impressive. 

6. ANTLERS ARE HEAVY. 

Just like the moose themselves, antlers can come in different sizes. The paddles are essentially a big bone, so they generally weigh quite a bit; bulls develop muscular necks to help hold up the enormous paddles. A full grown moose's antlers can weigh about 40 pounds. Anyway, this may be one of the most fascinating animal facts until now.

7. THE BABIES NEED HELP FROM THEIR MOM.

Female moose, or cows, generally have 1 to 2 calves in May. On average, the calves weigh about 30 pounds at birth and grow very quickly. Still, baby moose don't have the ability to run or protect themselves very well, so the mother stays with her offspring for a year and a half, fighting off wolves and bears that try to pick off the young calves.

8. THEY'RE GREAT SWIMMERS.

Moose are naturally gifted swimmers. It's common to see one hop right into a lake and swim across at up to 6 mph. The animals have an innate ability to know how to swim, so even calves can swim. 

9. THERE ARE FOUR SUBSPECIES IN NORTH AMERICA.

Moose can be categorized into four different species in North America: the eastern moose (A. alces americana), the Shiras moose (A. alces shirasi), the Alaskan moose (A. alces gigas), and the northwestern moose (A. alces andersoni), which Carstensen works with in Minnesota. Moose can be distinguished by different sizes and antler shapes. The largest moose is the Alaskan moose (pictured above) that can stand at 7 feet tall with an antler span of 6 feet. 

10. THEY'RE DYING AT AN ALARMING PACE.

Something is happening to all the moose in Minnesota. The state once had a flourishing moose population in the north that was hunted and doing quite well: In the mid-1980s, there were 2000 of the animals in the northwest, but that number dropped to less than 200 in just two decades. This prompted the state to do some research to prevent further drops in population. Unfortunately, the northeast is now facing similiar a problem; the moose population has dropped 50 percent since the mid-2000s.

• The greater bilby comes from the family of marsupials known as bandicoots. It is the largest among all the members of the family.
• According to the AustralianNationalUniversity, the animal has derived its name from an aboriginal language ‘Yuwaalaraay’.
• Its black coloured eyes, nearly 1 centimetre in diameter, do not make clear vision. Due to the poor vision, it solely relies on its strong sense of hearing and smell. The eyes are protected with the help of fine black eyelashes. This is one of the most interesting facts about Greater Bilby ever. 
• Built of a greater bilby comprises of long pointed nose, large hairless ears, white underside, black tail with a white crest. Because of its large ears, it is also known as Rabbit-Eared Bandicoot.
• The large ears of bilby aid in its effective hearing, as well as, strive to regulate its body temperature. They are also exceptionally manoeuvrable and can be rotated, made to stand flat against the body, positioned at right angles to the body and can even be folded in half.
• The soft and silky fuzz of bilby is primarily of pale blue-grey colours, with white and cream coloured undersides and feet.
• The stretched nose with hairless pink tip gives bilby an ability to smell sharply and smartly. You can witness many long, dark fuzz stick out from either side of the snout.
• A bilby has long slim tongue and 48 teeth: 26 on upper jaw and 22 on lower.
• It has slightly curved claws on the toes of its front feet. Whereas, on the feet of its hind legs, the second and third toes have slight joints with much larger fourth toe.

• Its claws and front legs are very strong which help it dig for its food and make deep burrows. An expert in digging, a bilby can dig up to a dozen of burrows. These burrows are generally spiral and as much as 3 meters deep.
• When a female bilby digs the soil, the dirt does not fill in its pouch as the pouch of a bilby opens in backward direction.
• The weight of an adult male bilby can go up to 2.5 kg. The weight of adult female bilby on the other hand, is significantly less (sometimes half) than that of an adult male.
• These are the nocturnal creatures that came out of their burrows nearly an hour after sunset and often go back in their burrows before first rays of the sun.
• The tail of a bibly is divided into three distinct sections: in the begining for a few centimetres, the colour of the tail resemble blue-greyish colour of the body; the middle section of the tail is black coloured, and at the end the tail is white.
• Bilby is a solitary animal, which prefers to roam alone. Although sometimes, bilbies are also seen in groups with at the most four members.
• Given that there is sufficient rainfall and food is available to them, bilbies can breed throughout the year. Let’s discover some interesting science facts that will amaze you.
• Having the smallest gestation period of all the mammals, greater bilbies breed one to three young bilbies in a litter.
• Infant bilbies remain in the pouch of their mother for nearly 80 days. It takes further 2 weeks till they become independent.
• Bilbies are the omnivorous creatures. Their food ranges from seeds, fruits, fungi to spiders, bulbs, small animals, insects and their larvae.
• A greater bilby consumes significant amount of mud along with its food.
• Bilbies do not drink water; rather, their food provides them with the requisite level of water to survive.
• Previously, they were hunted by Australians for food and fur. Other than humans, today they are preyed by foxes and feral cats.
• Before the European settlement, nearly 70% of the Australian Mainland had bilbies.
• At present, they are mostly seen in the south-west Queenslandand secluded parts of Western Australiaand the Northern Territory.
• The isolations of each of their colonies make them even more susceptible to diseases and inbreeding.
