TYPE OF NERVOUS SYSTEMS IN ANIMALS


   

         During the course of evolution, nervous systems have become more complex. This is largely because animals have become larger and more mobile, requiring more neurons than a sedentary animal. The most fundamental function of aa nervous system is,

  • To receive a stimulus
  • Transmission of a stimulus to a central “brain”
  • Interpretation and analysis of the stimulus
  • Proper response by effectors

                       with the evolution of a complex nervous system and bilateral symmetry, cephalization (formation of a head) has taken Place, and the ganglia in  the head became large enough to called a brain, which is the main nervous control center of the body.

there are several type of neural organization in the animal kingdom. In the unicellular from, the single cell functions both as receptor and effector, there are no structural specializations.

In the cnidarians (Coelenterates) specialized cell are found in the body which functions as neurons or nerve cells. These neurons are multipolar and non-myelinated and organized in the from of a diffused nerve net. This nerve network is located in the body wall (mesoglia)

In platyhelminthes a more complex nervous system basically resembling a ladder is present. In its basic from, a nerve ring or pair of cerebral ganglia is present in the anterior end of the body. The neurons of cerebral ganglia is present in the anterior end of the body. The neurons of this nervous system are non-myelinated. From this nerve ring two lateral solid nerve cords originate and passes towards the posterior end of the body. These two lateral nerve cords are connected by several transverse nerves which give a ladder like structure. Therefore platyhelminthes have a rudiment of a central nervous (brain and nerve cords) and peripheral nervous systems (transverse nerves).

BEE AND FLOWERS



             Karl Frich (1886-1982) was an Austrian zoologist who studied how bees communicate with other. In 1973 he received a Nobel Prize for his work on animal behavior.
             The sent from a flower that has produced nectar through the air. It may stimulate the receptor cell of a honey bee and the insect flies towards it. As it get closer, the bee uses its eyes to find the flower, its eyes are sensitive to ultraviolet light. This make some of the pale markings we see in normal light stand out more distinctly to help the bee identify the flower. Some of the markings are lines running down the inside of petal. They are called honey guides and direct the bee towards the nectar.

RESPIRATORY STRUCTURES IN ANIMALS

                           The simplest respiratory is surface, is the body covering. You may have noticed that some animals are small and shaped in a way that allow the body surface of the animal to be the gas exchange surface. However, as animals, as animals become bigger and complex their body surface to volume ratio gets decreased. Therefore, gaseous exchange through their body surface by simple diffusion become inefficient. Thus, s

Speed and Grace of the Cheetah


All children are sure to know about the cheetah. You would know that fastest land animal on Earth with the ability to run at speeds of 112 to 120 km/h (70 to 75 mph), accelerating from 0 to over 100 km/h (62 mph) in just three seconds. The speed and grace of this member of cat family have astonished humans and the sight of a stop us in our tracks.
                             Scientists think that about 10,000-12,000 years ago, at least 99 percent of the world king cheetah population may have died within a short period, resulting in the population getting as low as one pregnant female. The main difference between the king cheetah and the normal spotted cheetah is in the cat pattern. The standard cheetah’s fur coat is usually yellow, tawny or golden in color with a circular spotted pattern of small black markings, 0.75 to 1.5 inches in diameter, distributed fairly evenly across its body. The animal also displays the famous black ‘tear streaks’ down either cheek.

How Cruel the man on earth..?


              According to a wild life magazine, the total number of insects so far is in between one and two million.
               And….about ten thousand new species are identified annually.
     It could take another of that magazine, who is a conservationist, birdwatcher and active and dedicated supporter of wildlife conservation organizations… insects are the most abundant and successful animals on earth.
              Do you know the total number of other species living in this world today…?
                               The same wildlife magazine reveals that also …., But…, the total number of species living in this world today…, is staggering.
             These species are broadly categorized into Mammals, reptiles, Fish, Crustaceans, (shellfish like crabs and lobsters) amphibians, birds, insects and plants.
               Accordingly, there are nearly 4,600 species of mammals, 6400 species of amphibians, 8250 species of reptiles, 9700 species of birds, 26000 species of crustaceans, 20000 species of fish, 310000 species  of plants, and estimated four to six million insects living today.
       The variety of species in the forests of the world tigers, wolves, elephants, serpents, eagles, painted storks, caterpillars, luminous beetles. Insects, plants with leaves that close upon touch and pitches trap insects, was amazing. Don’t you think so…?
                                     The world’s largest mammal is the Blue whale, which can grow over 33 metres, long, and the smallest is the tiny bat from Thailand. Its size is about the size of a bumblebee and weighs just two grams.
                    The highest number of amphibians of any country on the earth is reported from Brazil. That is 751 species.
                           The largest living bird is, without doubt – the Ostrich. That magnificent bird stands a 2.7 metres high and weighs as much a 160 kg.  
                  The smallest bird in the world, is the ‘Hummingbird’ from Cuba, which weighs a mere 1.6 grams.
               However large number of animal species may be, many are under the threat of extinction, owing to poaching of wildlife, over fishing of the oceans, destruction of wildlife habit and climate change. 
          All of which have been brought by the most successful species on this earth-‘The man’. The number of species under threat is alarming..!
                              One fifth (1/5) of the mammalian species, one tenth(1/10) of birds, one third(1/3) of fish, one half(1/2) of plants, are under the threat of extinction, unless… immediate action is taken, to save them.

THE CEYLON ELEPHANT


The elephant is the king of the Ceylon jungle. No other animal dares to challenge his kingship. In their wild state, elephant live in small herds, about twenty-five in each. A full-grown male is usually the leader of the herd. Such a leader, in all his majesty and dignity, roams the jungle with his followers. Some elephants have tusks from which we obtain ivory; but “tuskers” are now rare in Ceylon.

RAINFORESTS


The importance of Rainforests
Tropical rainforests are located around the equator. The temperature around the equator is high. Hence the rate of water evaporation is high. As a result there is frequent rain in rainforests. They are found in South and Central America, Africa, in the islands around Australia and Asia. The rainforests are important to human existence and the surroundings. Rainforests are rich source of medicinal plants, food and useful forest products. They maintain about 50% of the plant, animal, bird, reptile and insect species of the world. These forests help to maintain a regular rainfall. They also stand as a buffer against floods, droughts and erosion. These forests produce a significant amount of the world’s oxygen. 


“Sinharaja” Rainforest in Sri Lanka.
The sinharaja forest is the only undisturbed rainforest left in Sri Lanka. It is about 9000 hectares in extent. Many of the plants are rave. Over 60% of the tree species are found only in the lowland wet zone of Sri Lanka. If these species of tree are allowed to get destroyed, the world would lose them altogether. So it is important that much effort is made to conserve this rich, valuable and fragile habitat.
             The sinharaja rainforest is the largest rainforest reserve in Sri Lanka. In 1840 Sinharaja became a crown property. In 1988 the Sinharaja was made National Wilderness area. In1989 UNESCO included the Sinharaja Forest in the World Heritage list, as the fist National Heritage of Sri Lanka.
                                The sinharaja forest is home to many rare animal, birds, butterflies, insects, reptiles and trees. Ferns and mosses grow well as the climate is humid because of heavy rainfall.
          
The vegetation
Vegetation means trees, shrubs and woody climbers. The average height of tree in the Sinharaja varies between 35 to 40metres. Some trees are above 50 metres.

The animals and the birds
Sinharaja provides a habitat for animals. The plants provide them with food. There are large mammals as well ones living there. The purple faced monkeys can be observed easily. They move about in groups. There are herbivores, carnivores as well as mixed feeders. The wild pig, the sambur, the mouse-deer and the barking-deer are some that you find in the Sinharaja. There is also evidence of the presence of the leopard. Among others are the rusty spotted cat and the fishing cat. There are many other varieties of small mammals.
                            Studies have recorded 147 species of birds. Some threatened species of birds are found in the Sinharaja. Among them are the blue magpie, the white-headed starling and the ash-headed babbler.



Reptiles



Studies have recorded 45 varieties of reptiles. These include snakes, lizards and tortoises. The viper and the cobra are among the venomous species. Conservation of sinharaja is of vital necessity. It ensures the maintenance of water resources. It also controls floods, which is a constant threat due to heavy rainfall in the area.
