Face of a male mandrill (Mandrillus sphinx). The vivid colouration on males' faces is used in threat displays between members of the troop. The females do not have the prominent red stripe on their noses, and their 'mane' (yellow) is less pronounced. Mandrill troops usually contain around 50 individuals. They inhabit the forests of western equatorial Africa, but spend most of their time on the ground. They retreat to the trees to sleep at night. Mandrills are omnivorous, eating roots and fruits as well as frogs, lizards and snakes. Small mammals are sometimes taken as well. Mandrills may reach a length of almost a metre. > Animals Copyright Toni Angermayer / Science Photo Library http://www.sciencephotogallery.com/pictures_1041194/Mandrill.html http://www.sciencephotogallery.com/pictures_1041194/1041194.jpg 2008-05-25T17:07:44Z dmcs-1041194 Piglets (Sus scrofa domestica) in a barrel.

From the time the eggshell is broken to the time the chick emerges is approximately 22 hours. The chick starts by breaking the eggshell with a sharp part of its bill. After an air hole is created in the egg, the chick will take several hours rest before enlarging the hole. The normal incubation time for a chicken egg is 21 days at 37 degrees C (100F). The eggs must be turned three times a day and kept at the correct humidity level. Leghorns are one of the best-known breeds of chicken. They produce the majority of the worlds crop of white eggs. > Animals Copyright Edward Kinsman / Science Photo Library http://www.sciencephotogallery.com/pictures_1064733/Hatching-Chicken-3-of-8.html http://www.sciencephotogallery.com/pictures_1064733/1064733.jpg 2008-06-06T13:21:06Z dmcs-1064733 Chick and egg. > Animals Copyright Cristina Pedrazzini / Science Photo Library http://www.sciencephotogallery.com/pictures_1064734/Egg-and-chick.html http://www.sciencephotogallery.com/pictures_1064734/1064734.jpg 2008-06-06T13:21:13Z dmcs-1064734 Horse (Equus caballus) and foal in a field, Holland. > Animals Copyright Ton Kinsbergen / Science Photo Library http://www.sciencephotogallery.com/pictures_1064735/Horse-and-foal.html http://www.sciencephotogallery.com/pictures_1064735/1064735.jpg 2008-06-06T13:21:31Z dmcs-1064735 Dark sheep in a light coloured flock (Ovis aries).

The robot has several dog-like behaviours, including barking, falling over and getting up, sleeping and walking. These behaviours are pre-programmed into its computer. The robot can be activated by remote control and also has a video camera in its head and sensors to allow it to respond to physical and visual cues from its owner. AIBO is also Japanese for buddy.

Coloured scanning electron micrograph (SEM) of an ant (family Formicidae). One of its compound eyes (red) is seen, as well as two long antennae that are mounted on the head between the eyes.

This sea anemone is found throughout the Indo-Pacific region and can reach up to one metre in diameter. Anemonefish, also called clownfish, live in association with anemones. Both partners benefit in a mutualistic association. Slime on the fish's skin prevents the anemone's stinging cells from damaging it. The fish sleeps, evades danger, eats, and lays its eggs between the poisonous tentacles. The anemonefish cleans the anemone and ensures a supply of food detritus for the anemone to feed on.

Coloured X-ray of a common lobster (Homarus gammarus). This is a marine scavenger that inhabits the cool waters of the north-eastern Atlantic Ocean. It is valued for its flesh.

The wood ant is social, and acts as a slave for the blood-red ant Formica sanguinea. Inseminated females of the blood-red ant invade wood ant nests, steal the pupae, and the ants that hatch are made to work for the strange queen. Magnification: x10 at 5x7cm size.

Thermogram of a polar bear (Ursus maritimus) with its mouth open. A thermogram shows variation in temperature on the surface of an object, measured by the long-wave infrared radiation it emits. The temperature scale is colour-coded and runs from white (-1.0 degree Celsius, coldest) through green, yellow and red to black (warmest, 34.9 degrees Celsius).The polar bear is adapted to live in a cold environment. Heat loss from its ears is reduced because of their diminutive size.

Coloured scanning electron micrograph (SEM) of the head of a silkworm moth caterpillar (Bombyx mori). The silkworm uses its chewing mouthparts (upper centre) to feed on mulberry leaves. On either side of the mouthparts is an antenna and several simple eyes (ocelli, black round structures, upper left and right). The caterpillar has three pairs of jointed legs behind the head (lower centre). Most caterpillars also have prolegs further along the body (not seen). The silkworm produces threads of silk with which it constructs a cocoon. People farm silkworms for their silk, which is woven into cloth.

Coloured scanning electron micrograph (SEM) of the head of a human flea (Pulex irritans). At upper centre are two sensory palps. At centre are the mouthparts, which pierce the skin to enable the flea to suck the blood of its host. Fleas are external parasites that may carry and transmit diseases, including the plaque. The itchiness associated with a flea bite is mainly due to an allergic reaction to the flea's saliva or faeces that have been deposited near the bite and rubbed into it by scratching.

Every house has millions of tiny dust mites, living in carpets and furniture and feeding on the flakes of skin shed by their human landlords. The average double bed contains about two million dust mites of various species. The body of the mite is made up of three regions: gnathosoma (head, at centre left); propo- dosma (with first two pairs of legs); hysterosoma (abdomen).

Coloured scanning electron micrograph (SEM) of the foot of a chameleon. Chameleons are the only lizards with zygodactyle feet, or with toes in a pincer arrangement.

Coloured scanning electron micrograph (SEM) of scales on the skin of a python (family Pythonidae). The scales of a snake protect it as it moves along the ground or through trees. They vary in size, with larger flat sales on the underside that help gain traction for movement. The scales do not grow and so as the snake grows it sheds its skin to reveal a layer of new, larger scales. > Animals Copyright Steve Gschmeissner / Science Photo Library http://www.sciencephotogallery.com/pictures_1064828/Python-skin-SEM.html http://www.sciencephotogallery.com/pictures_1064828/1064828.jpg 2008-06-06T13:35:40Z dmcs-1064828 Temple viper.

This venomous snake measures between 60 and 100 centimetres in length. Its vivid green colouration camouflages it against leaves in its tropical rainforest habitat in south-east Asia. The Wagler's pit viper is also called the temple viper. > Animals Copyright Gregory Dimijian / Science Photo Library http://www.sciencephotogallery.com/pictures_1064830/Waglers-pit-viper.html http://www.sciencephotogallery.com/pictures_1064830/1064830.jpg 2008-06-06T13:36:00Z dmcs-1064830 Island pit viper (Trimeresurus insularis) in the Tula Exotarium in Tula, Russia. > Animals Copyright Dante Fenolio / Science Photo Library http://www.sciencephotogallery.com/pictures_1064831/Island-Pit-Viper.html http://www.sciencephotogallery.com/pictures_1064831/1064831.jpg 2008-06-06T13:36:09Z dmcs-1064831 Machete savane snake (Chironius carinatus).

Emperor penguin (Aptenodytes forsteri) looking at its chick on the ice of the Antarctic coast. Female penguins lay a single egg in early winter which the males incubate for two months. The males huddle together, keeping the eggs off the ice by resting them on their toes. About the time the egg hatches, the females return from feeding at sea to feed the chick regurgitated food, while the males go off to feed. The emperor penguin is the largest species of penguin, reaching over 120 cm in height. Like all penguins, it is flightless, using its wings to swim through the water after fish and squid. Penguins have insulating layers of fat and waterproof plumage. > Animals Copyright Art Wolfe / Science Photo Library http://www.sciencephotogallery.com/pictures_1064835/Emperor-penguins.html http://www.sciencephotogallery.com/pictures_1064835/1064835.jpg 2008-06-06T13:36:43Z dmcs-1064835 Emperor penguins.

These birds are found in the sub-Antarctic and on cool islands in temperate areas in the southern hemisphere. They are social animals, living and breeding in large colonies. They feed on small fish and squid, diving below the surface of the water to catch their prey. They often hunt in groups, the older birds directing less-experienced individuals to the best feeding grounds. The king penguin is the second largest penguin in the world, reaching a height of around 1 metre and weighing approximately 13 kilograms. Only the emperor penguin is bigger.
