Camouflage in nature



The gliding lizard (Draco volans) is distributed in Southeast Asia, Malaysia, Indonesia, and the Philippines. It is also called flying lizard, which is not a very descriptive name, as it is not able to truly fly, but glides from one tree to another by spreading out its ribs, which are connected by a wing-like membrane, called a patagia.

The Eurasian golden plover (Pluvialis apricaria) breeds in Arctic and Northern Temperate areas, from Iceland and Scotland in the west, across northern Europe to central Siberia. Further east, it is replaced by the Pacific golden plover (P. fulva), whose breeding area reaches western Alaska, and in the remaining part of North America by the American golden plover (P. dominica). All three are very similar, with golden-speckled back and black breast in breeding plumage.

The generic name is from the Latin pluvia (‘rain’). Formerly, it was believed that when golden plovers flocked, it would mean imminent rain. In Icelandic folklore, the arrival of the first golden plover means that spring has come.

Praying mantises are a very successful group of insects, comprising more than 2,400 species, distributed worldwide in tropical and subtropical areas. They are ambush hunters, sitting motionless in the vegetation, waiting for suitable prey to approach. Their forelegs are enlarged and hooked, adapted for snatching and holding prey. As they sit there with their forelegs folded, their posture is not unlike a praying person, which gave rise to their common name. However, preying mantis would be a more proper name!

The common eider (Somateria mollissima) has an almost circumpolar distribution, found along Arctic coasts in Europe, eastern Siberia, and North America. It also breeds in some northern temperate areas.

Bush frogs of the genus Pseudophilautus, comprising about 80 species, belong to the family Rhacophoridae. This genus is restricted to Sri Lanka and the Western Ghats of southern India. Some species have already become extinct, while others are highly endangered.

The purple sandpiper (Calidris maritima) breeds in the Arctic tundra in northern Canada, Greenland, Iceland, and western Siberia, and along the Scandinavian mountain range. It spends the winter along shores of north-western Europe and the North American Atlantic Coast.

The little tern (Sternula albifrons) has a very wide breeding distribution, with main strongholds in west-central Asia and the Far East, and with scattered populations in Europe, western Africa, Indonesia, the Philippines, and New Guinea. In the 20th Century, most European populations declined drastically due to habitat loss, pollution, and human disturbance.

Marmots (Marmota) are 15 species of giant squirrels, which lives in underground dens in montane grasslands in Europe, Asia, and North America. The Himalayan marmot (Marmota himalayana) is found at altitudes between 3,500 and 5,200 m, throughout the Himalaya and on the Tibetan Plateau. Other species are presented on the page Animals: Squirrels of North America.

As their name implies, stick insects, or walking sticks, resemble sticks, or withered grass stems, making them difficult for predators to spot. These animals, which belong to the order Phasmatodea, are found on all continents, except Antarctica, with the highest diversity in the Tropics.

Scorpions are predatory animals, characterized by a pair of so-called pedipalps, with which they grab their prey, and their tail, often carried in a curve over the back, ending in a venomous stinger. Scorpions vary enormously in size, from Typhlochactas mitchelli, which is only 9 mm long, to Heterometrus swammerdami, which can grow to 23 cm. (Source: Guinness Book of Records)

Plants of the genus Lithops, of the ice-plant family (Aizoaceae), remarkably resemble the pebbles, among which they grow. This genus, comprising about 37 species, is confined to South Africa, Namibia, and Botswana. The generic name is from the Greek lithos (‘stone’) and ops (‘face’), referring to the similarity of these plants to small stones. Popular names include ‘living stones’ and ‘pebble plants’.
