s pouches, which are modification of the lower part of the bill, are their most obvious distinguishing features contrary to popular belief the pouch is used as sort of fishing net rather than as a place for storing food.
adaptation. All birds have feathers but no other animal has them. The feather is formed from the cells of the skin just similar to the formation of scales on the legs of birds or on the bodies of reptiles. The feather grows from the base inside a sheath. Bird's flight feathers have sufficient strength and firmness to remain quite rigid when moved through the air despite being anchored only at the base. Birds spend a significant proportion of their lives engaging in feather maintenance activities. Dirt on the wings is removed by bathing in water or in dust and any water or dust is subsequently removed by flapping the wings, ruffling the feathers and by preening movements. For preening they apply oil from preen or oil gland. This gland is found in most birds and is situated on the rump above
the base of the tail. It produces an oily secretion and is most active in aquatic birds. The secretion helps to keep feathers supple so that they do not break and increase their water proofing qualities. Despite their resistance to wear, feather must be renewed at intervals. The moulting process, during which old feathers fall out and are replaced by new ones growing in the same place, also allows birds to change from juvenile to adult plumage or from non-breeding to breeding plumage.
e under cavities of large tree roots and under the rocks. They prefer to hunt in night and rests in days. There are around 70 species worldwide.
walks sideways with these legs leading the ways. The leg-like mouthparts are stout, spiny and used to capture and hold insect prey while it is ton by the fangs. Whip Scorpions are purely nocturnal hunters feeding mostly on insects such as cockroaches, grasshoppers and sometimes on centipedes. These are not at all venomous for human. Although these animals may look extremely dangerous and frightening, they are perfectly harmless and very shy.
d, when the eggs are laid they are inside a special membrane that prevents them from drying out. The female remains in the end of her burrow guarding the eggs. When the eggs hatch the young are white and look nothing like their mother, they climb onto her back and attach themselves there with special suckers. After a while they moult and the creature which now emerges looks like a miniature Whip Scorpion. After first moult they leave their mother. The young are slow growing and they gain maturity around the age of three years.

they are active during nights. Amphibians in the dry region tend to absorb water through skin from moist soils. Amphibians can change their skin color according the surrounding environment. Amphibians use gills, lungs and skin for the respiratory purposes.
the family Rhacophorous with extensive webbing that are able to glide by extending their limbs out as they jump, thus serving to increase their surface area. These species are arboreal, with strong jumping skills. This particular frog is Philautus waynadensis, one of the widely distributed and a common frog in the Western Ghats. In the past this species was referred to as Philautus leucorhinus. It is commonly called whitenosed bushfrog. It is endemic bushfrog with lower risk of extinction. Among the leaf frogs, eggs are usually deposited on leaves above ponds, where mothers keep them wet by urinating on them. Hatchlings fall into the water below.Insect Orchestra
In early monsoon our forests are full with insect orchestras. The loudest instrumentalist in the animal world is by the insects. They do not have ears and have some h
earing organs, but some species have developed remarkable efficient ways of producing sound as well as receiving it. It is nearly always the male that is equipped with the sound making equipment and thus he must make the first moves in courtship game.
The synchronized screeching of cicadas fills the air and is often painfully clear. The cicada song is so loud that it can sometimes be heard up to one kilometer away. When ready to mate, the male cicada positions himself high up in a tree and begins calling loudly to attract the mate. Hi
s song sparks off a chain reaction and suddenly all the males in the area will also burst into song. The sound of so many males seeking her attention quite overwhelms the female who flies right into the middle of this singing orchestra. Of course soon she finds her best male and they start for the new generation.
The cicadas, along with crickets and grasshoppers, are loudest and mist musical in the insect world and have remarkable complex ways of producing their unique sound. The male’s sound production mechanism consists of two hard plates called “tymbals” on either side of its thorax. By rapidly flexing strong muscles, the insect manages to buckle and unbuckle these plates to produc
e its characteristic ticking sound. What is more, the male cicada has a volume control over his songs – a special covering that acts as a damper when it is lowered. This, combined with a prodigiously fast output of ticks that can reach upto 1000 per second, gives cicada an instrumental voice of some versatility for charming a prospective mate. The sound is differentiating between the species and those cicadas able to produce more clicks per second can vary their songs to make them distinct from other varieties. In addition to this cicadas can, by raising and lowering a cover over the tymbal, make their song louder or quieter.

Pit Vipers with “Sixth” sense.
Some snakes have infrared vision also called “heat vision,” the infrared rays, which have longer wavelengths than those of visible light, signify the presence of warm-blooded prey in 3 dimensions, which helps snakes aim their attacks. Pit vipers possess this ability; have heat-sensitive membranes that ca
n detect the difference in temperature between a moving prey - such as a running mouse.
The detection system, which consists of cavities located on each side of the head called “pit organs,” operates on a principle similar to that of a pinhole camera. A pinhole camera is a camera without a lens, where light from an image passes through a very small hole. Similarly, a pit organ’s aperture is about 1 mm—large enough to allow the snake to quickly detect moving prey. In pit vipers, which have only two pit holes (one in front of each eye), a block of about 1,600 sensory cells lie on a membrane which has a field of view of about 100 degrees. This means the snake’s brain would receive an image resolution of about 2.5 degrees for point like objects, such as eyes, which are one of the hottest points on mammals. This head of Bamboo pit viper shows a nostril, pit hole and eye (right to left). This is one of the poisonous snakes found near us. The Bamboo Pit Viper is a pale green snake with f
aint, uneven black patterns on the back. The head is wide and triangular, set on a thin delicate neck. Actually this type of head is found in all types of Vipers and is one of the identification keys. This snake’s eyes are with golden iris and a black vertical pupil. This snake prefers living in vines, bushes and bamboo. Bamboo Pit Viper are slow moving snake and nocturnal. They rely on camouflage for protection. Although slow to defend themselves, they are capable of fast strikes and bites if disturbed. The food of this snake consists small mammals like rodents, lizards, birds and frogs. The female give birth to 4 or 5 living young. This is also Viper specialty as other snakes lay eggs. These Bamboo Pit Vipers are small in size near about 75 to 80 cms in adults. Their venom is low in toxicity, so that bites are rarely serious.

Spider female guarding egg sac.
Female spiders are usually larger than the male as the physical demands and accompanying energy requirements to produce webs and broods, are far greater. The male is smaller because once mature, his only function is to mate. Where males are similar in size to the females, they are generally more slender
, with longer legs. In some cases the male can be one thousandth of the weight of the female. In other cases, the male and female are so different that they may even appear to be different species where males of certain species mimic wasps or ants.
Once mature, the male abandons all usual activities such as web construction and prey capture and transforms into a sexual attractions. Spider courtship is hazardous for the male spiders. It requires planning ahead, a good strategy, knowing the whims of your future mate and in some cases, the ability to perform long, arduous routines
to please her - sometimes at the risk of being eaten by her. Once he has located a mate, the male spider dare not make a false move as it would mean certain death so the female is approached cautiously.
As the eggs develop in the female, her abdomen enlarges. After a period varying from 1 week to several months after mating, the female lays her eggs in the safety of darkness. About 1000 eggs can be laid in 8-10 minutes. Some spiders only produce a few eggs while few species can produce up to 9000 eggs and only about 2% survive to maturity. Spider eggs are roughly spherical, and about 1 mm in diameter; they are laid in a compact mass and covered to a greater or lesser extent with silk, forming a sac. The eggs are variously colored, pale brown, pale yellow, pink, even bright green. Underfed females lay less eggs but the size depends upon the species. Some spiders produce more than one sac, but there is a tendency for fewer eggs in the later sacs. Most species however spin much
more substantial cocoons or egg-sacs to hold the eggs safe. This is particularly necessary to species where the mother dies before the eggs hatch. But some wolf spiders however live to see their young hatch.
The tiny hairless and blind creature must wait a few days to moult into a more advanced stage, the larva, which has rudimentary eyes and a few hairs but lacks poison and the ability to spin silk. Both of these stages are unable to feed and they subsist off the yolk within them. After a short period, the larva moults into a nymph or spiderling which resembles the adult in general form. At this stage, some cannibalism may take place within the sac, and those spiderlings which are weak becomes meal for others.

back. It may have small, white, diamond-shaped and somewhat square patches along the middle of the back, which may join laterally the wavy white line mentioned above. The head is triangular and has got a distinct white mark on it which somewhat resembles the foot-print of a bird, or may be likened to a broad arrow or a trident. The belly is white and covered with light-brown or dark spots. There is no pit between the nose and the eye which shows that, like Russell's Viper, it belongs to the class of pitless vipers. The broad bellyplates, small scales on the head and tail shields which are entire are

very marked, the bitten part may slough and the person die of septic poisoning. There is also a tendency to bleed from various parts of the body a few days after the bite, and so a doctor should be consulted as soon as possible after the bite. This snake is considered to be the world's most dangerous snake because of its highly toxic venom, its abundance near cultivated areas, and its aggressive, easily excitable temperament. The venom is used in the preparation of anti-venom. These snakes keep the locust and rodent population in control and also feed on frogs, toads, lizards and other small insects. Female gives birth to 12 - 15 young ones at a time.
iles whose soft body is covered by a hard shell. Most turtles can pull their legs, tail, and head into the shell for protection. Like other reptiles, all turtles are cold-blooded; their body temperature about matches the temperature of their environment.
rust of the long neck. The turtle is able to withstand prolonged starvation. A captive turtle lived for two years without taking food. This group is long lived and there is longevity record of 152 years of giant tortoise which lived from 1766 to 1918 in one of the Seychelles Islands.
spend their entire life within a short distance from where they were hatched, but most sea turtles migrate thousand of miles. Sea turtles are also fast swimmers; but on land most kinds of turtles are slow. Most turtles are omnivores that are they eat both plants and animals but the exact foods consumed vary between the species. Today over 40 species of turtles including most sea turtles and many types of tortoises are endangered, and if turtle conservation and protection does not improve, certain species will become extinct forever.
yellow markings. Paper wasps will defend their nest if attacked. Adults forage for nectar, their source of energy, and for caterpillars to feed the larvae (young). They are natural enemies of many garden insect pests.
spired by observing these wasps chewing bark. Other members of the Vespid family, are potters, building their nests from mud and saliva. The nests are constructed in protected places, such as under the eaves of buildings or in dense vegetation. Normally a colony of several to several dozen paper wasps inhabits the nest.
takes over. This worker begins laying eggs and continues to dominate all below her. Since the workers have not mated, they can only lay unfertilized eggs, which develop into males, a typical trait in wasps.
for ghost, it's a comparison they certainly deserve. There are around 2700 species of Phasmida in the world. Mostly, they live in the tropics, but they also occur in the temperate regions of Australia, New Zealand and Europe.
hes on which they live. Most walkingsticks are slow-moving insects, a behavior pattern that is consistent with their cryptic lifestyle. In a few tropical species, the adults have well-developed wings, but most phasmids are brachypterous (reduced wings) or secondarily wingless. Stick insects are most abundant in the tropics where some species may be up to 12 inches in length. Females do not have a well-developed ovipositor so they cannot insert their eggs into host plant tissue like most other insects. Instead, the eggs are dropped singly onto the ground, sometimes from great heights. Stick insect's eggs often resemble seeds. The eggs may remain dormant for over a year before hatching.
of some phasmids may separate from the body. Some species can even regenerate lost legs. These are the only insects able to regenerate body parts. In addition to their foliage mimicking defensive strategies, there are some glands located on the thorax of stick insects can produce a foul-smelling liquid that repels predators.
is called “Sarpa tol” or “Haran tol” in marathi. The body is uniform parroty-green, often with a thin white or yellow line separating the black scales from the belly scales. The underside is fluorescent green or yellow. When excited it shows the inflated neck and body revealed black and white inter-scale color gave a banded appearance. The scales are very much soft and smooth but not shiny. This is the only snake in India, which have horizontally elliptical eyes and bright golden iris. These, coupled with forward position of the location of the eye, give this snake a very good vision. These eyes are large and give it near stereoscopic vision which would clearly assist it in its hunting techniques. This is a common snake still rarely seen because of their excellent camouflage. It is distributed all over the India except northwest
parts and it prefers bushes and small trees. It remains suspended by its long thin tail, the head being held free from the coil.
irds. Its superb camouflage enables it to stalk its prey with ease. Once the prey is in striking distance it coils itself and darts towards its prey with lightning speed. The prey is often seized by the neck and killed by suffocation caused by crushing its victims throat with its jaws. Its venom plays a minor role in its hunting but does appear to assist in the killing process. This snake waits until its prey is completely dead before swallowing it.
rous plant. There are many noncarnivorous plants that do some (but not all) of these things. For example, flowers attract pollinators (such as insects, birds, and other creatures, even humans!); some plants such as orchids and water lilies temporarily trap insect pollinators to ensure pollen transfer. All plants absorb nutrients either through their roots or leaves. However, even though these plants do some of the things that carnivorous plants do, they do not fulfill all of the criteria necessary to qualify as a carnivorous plant. Only plants which attract, capture, kill, digest, an
d absorb prey are truly carnivorous.

rder after beetles and flies that had evolved about 155 million years ago. The digger wasp first prepares a burrow in a suitable spot, and then starts digging. When a little hole is made, then she enters it and comes out carrying soils between her curved forelegs and her head, repeating this till there was a considerable heap of soil. This heap she then demolishes by standing and kicking it away with her hind legs, leaving no evidence of its excavation. Before beginning hunting she makes a complex series of short flights around and above the nest site, fixing in her mind a visual pattern of its location and of prominent landmarks by which it can be locates from long distance. A major disadvantage of preparing the nest in advance lies in the necessity of transporting the prey when it is obtained at some long distance. Many times wasp hunts for larger prey, sometimes heavier than herself, and may have a long and difficult task dragging the loa
d over rough terrain and through dense, tangles vegetation.

, the antlion is busy chucking sand at it, again using its head and jaws. Eventually the shower of sand may knock the ant within the antlion’s reach. Once seized, the ant is dragged into the sand at the bottom of the burrow where it is consumed. Adults Antlion have short antenna which thicken towards the tips. They are medium to large size with long wings. Most of them are predators on other insects although some feed on pollen. They have two pairs of membranous wings like the dragonfly, but Antlion flies slowly and short distance.
