Thistle is the common name of a polyphyletic group of flowering plants characterised by leaves with sharp spines or prickles on the margins, mostly in the plant family Asteraceae. Their prickles often occur all over the plant, including on the stem and flat parts of the leaf. These are an adaptation to protect the plant against herbivorous animals, discouraging them from feeding on the plant.

A 'roarity' - IV

The chinchilla mutation, a recessive gene and not albinism gives white lions their distinctive colour. They vary from blonde through near white, but some can also be red. A most recent count done in 2004 put their number at 30. Because the gene is recessive and is masked by the normal tawny color, white lions remain rare in the wild and only occur when two lions carrying the mutant gene are mated.

Singing Beach gets its name from the sand that sings when you walk on it. Actually, reports say that it's more of a squeak than a melody, but you get the point. Conditions must be right for this phenomena to occur; not too wet, not too dry, etc. There are many sandy places in the US that exhibit this phenomenon and the more unsettling occurence of booming sand. Many are in deserts, so it's not the ocean that's doing it.

Coprinellus disseminatus

The Fairy Inkcap, Coprinellus disseminatus, rarely ventures forth alone or even with just a few friends; more often it forms dense masses swarming over rotting tree stumps and roots. These gregarious little fungi occur from early spring until the onset of winter, and they are at their most spectacular when the caps are young and pale - sometimes nearly pure white. It takes just two or three days for young white caps to turn grey and then begin blackening.

Widely distributed in the Northern Hemisphere across Europe, Asia, and North America, it does not occur naturally in the Southern Hemisphere, although it has been introduced to southern Africa, Australia and New Zealand.

Garden Spider (Araneus diadematus)

This spider (Araneidae) are probably the best known families of spiders. Described about 2600 kinds, in the Czech Republic from 39th to occur

They are massive, are well armed with teeth - three to four commonly. The median eyes are square in the middle of the forehead, side of them are noticeably delay. The tail is usually rounded to ovate, often much larger than the cephalothorax, the legs tend to have many different shades. The family is small, and very large spiders (2-38 mm), males are often much smaller than females.

The Green and Golden Bell Frog

The Green and Golden Bell Frog, Litoria aurea, is a magnificent looking frog and can often be mistaken for a garden ornament! In the late 1860s several consignments of these frogs were received from Sydney and released by the Auckland Acclimisation Society. There have been several attempts to establish populations of this species in the South Island, but it appears that the climatic conditions are not favourable and the species is restricted to the upper half of the North Island (north of Gisborne). They occur around the same ponds as the Southern Bell Frog and may interbreed

The black bear Ursus americanus is one of the most familiar wild animals in North America today. Black bears are members of the family Ursidae, which has representatives throughout most of the northern hemisphere and in some parts of northern South America. Other members of this family that occur in North America are grizzly bears and polar bears. Both of these species are considerably larger than the black bear. This photo was taken in Omega Park of Quebec.

Most of the remaining trees due to erosion / abrasion that often occur around the coast. Abrasion is the process of coastal erosion by sea waves and ocean currents that are destructive. Abrasion is usually referred to coastal erosion. Shoreline damage due to abrasion is driven by the disruption of the natural balance of the coastal area. Although the abrasion could be caused by natural phenomena, but the man often referred to as the main cause abrasion. One way to prevent abrasion is by planting mangrove forest.

Clover (Trifolium), or trefoil, is a genus of about 300 species of plants in the leguminous pea family Fabaceae. The genus has a cosmopolitan distribution; the highest diversity is found in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics.

A leaf insect - walking leaves - popular names of the Phylliidae family.

Leaf insects use camouflage to take on the appearance of a leaf. They do this so accurately that predators often aren't able to distinguish them from real leaves. In some species the edge of the leaf insect's body even has the appearance of bite marks. To further confuse predators, when the leaf insect walks.

Moeraki Boulder NZ

The Moeraki Boulders are unusually large and spherical boulders lying along a stretch of Koekohe Beach on the wave-cut Otago coast of New Zealand between Moeraki and Hampden. They occur scattered either as isolated or clusters of boulders within a stretch of beach where they have been protected in a scientific reserve. The erosion by wave action of mudstone, comprising local bedrock and landslides, frequently exposes embedded isolated boulders. These boulders are grey-colored septarian concretions, which have been exhumed from the mudstone enclosing them and concentrated on the beach by coastal erosion.

Ban Gioc Waterfall - Detian waterfall

Ban Gioc Waterfall is one of Vietnam’s most impressive natural sights. Located in the northeastern province of Cao Bang, the falls are 30 metres high and 300 metres across, making Ban Gioc the widest – but not the highest – waterfall in the country. The falls occur on the Quay Son River, a beautiful jade-blue body of water, flowing through a pastoral landscape of rice fields and bamboo groves, surrounded by limestone pinnacles.

Into the sunset.

Sunset or sundown, is the daily disappearance of the Sun below the western horizon as a result of Earth's rotation. The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun's disk disappears below the horizon. The ray path of light from the setting Sun is highly distorted near the horizon because of atmospheric refraction, making the sunset appear to occur when the Sun’s disk is already about one diameter below the horizon. Sunset is distinct from dusk, which is the time at which the sky becomes completely dark, which occurs when the Sun is approximately eighteen degrees below the horizon. The period between sunset and dusk is called twilight. Sunset or sundown, is the daily disappearance of the Sun below the western horizon as a result of Earth's rotation.
