Why Pigs Need Mud

Why Pigs need mud? Can you give us the best explaination? If you can't, let's find out here to know and also get other fact of life I have found as below


Pigs roll in mud primarily in order to regulate their body temperature. This behavior is more commonly referred to as "wallowing."

As well as offering protection from the sun's rays, a coating of moist mud is crucial for keeping pigs cool in warm weather through gradual evaporation. This method is so effective that some have suggested wallowing as the reason for the limited evolutionary development of sweat glands in pigs. Pigs also wallow in cooler weather, indicating additional motivations such as the removal of parasites, and possibly marking territory with scent. Of course, pigs also genuinely enjoy wallowing for its own sake, showing signs of distress when farmers attempt to curb their behavior with anti-parasite medicines or air-conditioned barns.

A wide range of Pangolin facts

Below is a wide range of Pangolin facts and their physical characteristics


Pangolin species vary in size from about 1.6kg (~3.5 lbs) to a maximum of about 33kg (~73 lbs). They vary in color from light to yellowish brown through olive to dark brown. Protective, overlapping scales cover most of their bodies. That might be one of the most awesome animals facts you had no idea before. These scales are made from keratin — the same protein that forms human hair and finger nails. Overlapping like artichoke leaves, the scales grow throughout the life of a pangolin just like hair; scale edges are constantly filed down as pangolins dig burrows and tunnel through the soil in search of termites and ants. Pangolin undersides do not have scales, and are covered with sparse fur. Unlike African pangolins, Asian pangolins also have thick bristles that emerge from between their scales.

With small conical heads and jaws lacking teeth, pangolins have amazingly long, muscular, and sticky tongues that are perfect for reaching and lapping up ants and termites in deep cavities. Pangolins have poor vision, so they locate termite and ant nests with their strong sense of smell. A pangolin’s tongue is attached near its pelvis and last pair of ribs, and when fully extended is longer than the animal’s head and body. At rest a pangolin’s tongue retracts into a sheath in its chest cavity. A pangolin’s stomach is muscular and has keratinous spines projecting into its interior. Usually containing small stones, the stomach mashes and grinds prey in much the same manner as a bird’s gizzard. Wanna take a quick look at funny pictures with captions that can help you relax effectively.



Pangolin limbs are stout and well adapted for digging. Each paw has five toes, and their forefeet have three long, curved, claws used to demolish the nests of termites and ants and to dig nesting and sleeping burrows. Pangolins shuffle on all four limbs, balancing on the outer edges of their forefeet and tucking their foreclaws underneath as they walk. They can run surprisingly fast, and will often rise on their hind limbs to sniff the air. Pangolins are also capable swimmers, and while some pangolin species such as the African ground pangolin (Manis temmincki) are completely terrestrial, others, such as the African tree pangolin (Manis tricuspis), are adept climbers, using their claws and semi-prehensile tails to grip bark and scale trees.

Facts and infor about seed plants

Facts and infor about seed plants are all shown here. Let's have a view at it now.


INSIDE A SEED

A seed is the first stage in the life cycle of a plant. Protected inside the tough seed coat, or testa, is the baby plant, called an embryo. Food, which fuels germination and growth, is either packed around the embryo or stored in special seed leaves, called cotyledons.

SPREADING WITHOUT SEEDS

Seeds are not the only means of reproduction. Some plants create offshoots of themselves – in the form of bulbs, tubers, corms, or rhizomes – that can grow into new plants. This type of reproduction is called vegetative reproduction. As only one parent plant is needed, the offspring is a clone of its parent. This might be one of the most weird facts about them.
 
Bulb

A bulb is an underground bud with swollen leaf bases. Its food store allows flowers and leaves to grow quickly. New bulbs develop around the old one.

Tuber

A tuber is a swollen stem or root with buds on its surface. When conditions are right, the tuber’s food store allows the buds to grow. Still boring? Check out our funny images to get relaxing moments in your freetime.
 

Corm

A corm is a swollen underground stem that provides energy for a growing bud. After the food in the old corm is used up, a new corm forms above it.

Rhizome

A rhizome is a horizontal stem that grows underground or on the surface. It divides and produces new buds and shoots along its branches.

GERMINATION OF A RUNNER BEAN

Most seeds require damp, warm conditions in order to sprout. During germination, the seed absorbs water and the embryo starts to use its food store. A young root, or radicle, begins to grow downward. Then a young shoot, or plumule, grows upward. This develops into the stem and produces leaves. The first leaves, called seed leaves or cotyledons, fuel the early growth until the plant’s true leaves appear.

FRUITS

A flower’s ovary usually develops into a fruit to protect the seeds and help disperse them. A fruit may be succulent (fleshy) or dry. Fruit is often tasty and colourful to attract fruit-eating animals. Its seeds can pass through an animal unharmed, falling to the ground in droppings. Seeds may also be dispersed on animals’ coats, by the wind, or by the fruit bursting open.

DRY FRUITS

The seeds of dry fruits are dispersed in various ways. Peapods are dry fruits that split and shoot out their seeds by force. The hogweed fruit forms a papery wing around the seed, helping it to float on the breeze. The strawberry is a false fruit, but it is covered by tiny dry fruits, each with a seed.


SUCCULENT FRUITS

Fleshy, brightly coloured, and often scented, succulent fruits are designed to attract the animals that eat and disperse them. Fleshy fruits such as apricots and cherries have a woody stone or pip that protects the seed. Called drupes, these fruits form from a single ovary. Many drupes, formed from many ovaries, may cluster to form a compound fruit, such as a raspberry.
