Predatory animals. wolf family

Wolf family. A typical representative is a wolf. It lives throughout Russia - from the tundra to the southern steppes. They lead a wandering lifestyle, uniting in flocks. During the breeding season, they form pairs. The lair is arranged in remote places, under the roots of trees. The she-wolf brings 4-6 puppies. They feed on rodents, hares, birds, and ungulates. Puppies are fed by both parents. They hunt alone or in packs, chasing prey.

Common fox. The size, color and nature of the fur depends on geographical conditions. Distributed everywhere. Leads a nomadic lifestyle. Forms pairs during the breeding season. The fox digs a hole itself or occupies the minks of other animals. Once a year it brings 4-6, sometimes up to 10 blind cubs, which grow rapidly and can leave the hole in a month. Active around the clock, but especially in the evening and at dawn. It feeds on live prey: it pursues it, and digs up rodents. The fox destroys sick and dead animals.

Bear family. Three types of bears live in our country: white, brown and black. Bears are distinguished by their large body size, thick hair, and sharp, non-retractable claws on their paws. Bears are plantigrade mammals with short tails. Distributed in the northern hemisphere. They eat both animal and plant foods. The female gives birth to 1-2 cubs, very small, blind.

Polar bear. The largest of the bears is up to 3 meters long, weighing up to 1 ton. Does not hibernate. In the snowy lair, arranged under the rocks, lies only the female, who is preparing to become a mother. The number of the polar bear has been reduced, it is under protection.

Brown bear. The brown bear lives in Siberia, the Caucasus, in the mountains of Central Asia. Prefers forests rich in berries with swamps and ravines. In winter, it hibernates. The lair is arranged in remote areas of the forest, using natural shelters. In lean years, the bear does not sleep, this is called a connecting rod. He is very dangerous: he attacks domestic animals, ruins the hive. In December-February, the female gives birth to 1-3 cubs.

Characteristics of cats. Predators are large and medium, with long limbs armed with retractable claws. The coloration is spotted or striped. The carnivorous teeth are well developed. They feed on live prey, which they watch for and rush from an ambush. Distributed on all continents except Australia.

Tiger. The tiger is the largest of our cats. Up to 3 meters long, weighing 350 kg. Lives in the Far East and Central Asia. Leads a nomadic life, active at all times of the day. The lair suits in the bushes, less often among the rocks. It breeds every 2-3 years. There are 2-6 kittens in a litter. They become sexually mature at 4 years of age. They feed on ungulates: deer, roe deer, wild boars. After eating, he likes to rinse his mouth. The tiger is a rare animal, taken under protection.

The text of this presentation

Predatory animals
The presentation was made for a biology lesson by a student of grade 6 A

Who are the predators?
PREDATORY Beasts (Carnivora), a detachment of mammals. According to modern concepts, it includes the families of wolves, bears, raccoons, hyenas, mustelids, viverrids, mongooses, felines, as well as three families that were previously united in the order of pinnipeds: seals, eared seals and walruses; only about 270 species. They are distributed all over the world, in Russia only viverrids are absent. Body sizes of adult animals can be from 12 cm with a weight of 50 g (weasel) to 3 m and 700 kg (polar bear) and even 6.5 m and 3000 kg (elephant seal). Specific features of the body structure and lifestyle are very different in representatives of different systematic and ecological groups. Various species of carnivores can lead a terrestrial (most species), semi-arboreal (some viverrids, raccoons), semi-aquatic (otter) and aquatic (sea otter, seals) lifestyle. They inhabit a variety of landscapes - from arctic deserts to deserts and highlands. Most species feed mainly on animal food, but among terrestrial forms there are also omnivores and even predominantly herbivores (for example, the giant panda). Some species are distributed over very large areas, occur in various biotopes, and are characterized by a wide food spectrum. Others are characterized by a narrow biotopic or food specialization. Terrestrial carnivores are characterized by monogamy and the birth of underdeveloped and blind cubs.

WOLF (canine, canine; Canidae), a family of mammals of the order of predatory animals, includes 11 genera (about 35 species), including maned wolves, red wolves, arctic foxes, raccoon dogs, phoenixes (all in one species), wolves, foxes . Most of the species are included in the wolf subfamily. They always live in a pack of 6-8 animals. The main feature of the wolf character is “friendliness”. The length of an adult wolf from the tip of the nose to the tail is 2 meters. They weigh 43-45 kg. Smell 1.5 km away. Hardy Run 65-80 km per day at a speed of 55-60 km / h Eat up to 6 kg of meat in one sitting, hide the rest in reserve

Mustelidae, or marten (lat. Mustelidae) - a family of mammals of the order of carnivores. They are one of the most species-rich families. Mustelids appeared 40 million years ago, their size for predators is quite small. Mustelids include martens, minks, otters, badgers, ferrets, and so on. Mustelids are able to adapt well to various conditions, therefore they are represented in all parts of the world.

ROCCOON (Procyonidae), a family of mammals of the order of carnivores; includes 8 genera, 15–21 species. Most of the raccoons are medium-sized animals with an elongated flexible body (31–67 cm), a long (20–69 cm) tail, some of them prehensile. Weight from 0.8 to 22 kg. The muzzle of almost all is short, pointed, the ears are erect. Feet with long prehensile toes, plantigrade or digitigrade, sometimes with semi-retractable claws. Color varies from gray to bright reddish-brown. There are often marks on the muzzle, a ringed tail pattern is characteristic. Most species live in South and Central America, one species - in North America, two species - in Asia (pandas). Raccoons live mainly in tropical, mixed and mountain forests. Some species plunge into hibernation (raccoon-poloskun). Raccoons feed on amphibians, fish, rodents, as well as plant foods (fruits, berries) and insects. They breed once a year, usually from 2 to 6 cubs are born. Some species (raccoon-poloskun) are an object of fur trade.

Hyenas (Hyaenidae), a family of predatory mammals; includes four types. Hyenas are quite large animals: their body length is 55-165 cm, tail 20-33 cm, weight 10-80 kg. They have a short body. The head is massive, in most species with powerful jaws. The legs are strong, somewhat curved. The forelimbs are longer than the hind ones. Real hyenas have 4 fingers on both legs, the earthen wolf has 5. The claws are long, but blunt, convenient for digging. The coat is coarse, shaggy, on the ridge in the form of a long standing mane. The general color tone is dirty, yellowish-gray, or brown, with a striped or spotted pattern on the whole body or only on the legs. Hyenas are common in Africa, Western, Central and Southwestern Asia. One species is the striped hyena (body length about 1 m, tail about 30 cm) in Transcaucasia and Central Asia. The smallest species is the earthwolf (Proteles cristatus). The length of its body is up to 80 cm, the tail is up to 30 cm. It is common in East and South Africa. The earthwolf does not feed on carrion, unlike other species, but mainly on insects and their larvae (termites), less often on small mammals and birds. An important means of protection are the secretions of the anal glands, which scare away predators. The spotted hyena is the largest member of the hyena family. The number of hyenas is declining due to a decrease in wild ungulates, the corpses of which hyenas mainly feed on. The brown hyena (Hyaena brunnea) and the striped hyena are listed in the International Red Book.

Viverrids (Viverridae), a family of mammals of the carnivore order (Carnivora). Mostly small slender animals with short legs and long tails; many V. are similar in appearance to representatives of the weasel family. Some have special glands located near the anus and secrete an odorous secret - civet. 36 (or 37) genera, including about 75 species (the largest family of the carnivorous order). Distributed in South Asia, Africa (including Madagascar) and Southwestern Europe. They lead a terrestrial lifestyle, some live in trees. They feed on small animals, sometimes fruits and nuts. Main genera: genet (6 species), civet (3 species), binturong (one species), fossa (one species), ichneumons (8 species), mungo (one species), African civet (Civettictis, one species), African palm civet (Nandinia, one species), etc. Many V. are an object of hunting; civet is used in perfumery and medicine. Some V. are also kept in captivity to obtain civet.

Tiger (lat. Panthera tigris) is a species of predatory mammals of the cat family, which belongs to the subfamily of big cats. Reaches a length of 3.5 meters. Weighs 300 kg. A hungry tiger eats everything: deer, bulls, cows, buffaloes, lynxes, wolves, fish, locusts, snakes, frogs, mice. They live closer to the reservoir, swim well. Tigers hunt in the evening. They kill a horse with one blow of their paws.

What is developed?
Perfection of the brain A high level of nervous activity, characteristic of predatory animals, is ensured by a great perfection of the brain. It has well-developed hemispheres with three grooves, numerous convolutions, and large olfactory lobes. The number of respiratory movements in mammals depends on the size of the animal, which determines the different metabolic rates. It is (in 1 minute): in a horse - 8-16, in a black bear - 15-25, in a fox - 25-40, in a rat - 100-150, in a mouse - about 200. Ventilation of the lungs not only provides gas exchange, but it also has thermoregulatory significance. When the temperature rises, the number of breaths increases, and with it, the amount of heat removed from the body also increases. So, in a dog, the ratio of heat transfer during breathing to its total loss at an air temperature of 8 ° C is (in percent) 14, at 15 ° C - 22, at 30 ° - 46. All sense organs are well developed. All organs are well developed in predators. feelings. Especially the sense of smell: it is stronger than human in thousands of times. The sense of smell gives the predator more information about the world around him than his sharp eyesight.

Predator birds
Birds of prey are birds that hunt in flight. They have good eyesight, large claws and a beak adapted to capture or kill prey. Birds of prey do not constitute a single taxonomic group, but represent several taxa united by common features. Most diurnal birds of prey belong to the Falconiformes order: Accipitridae (Accipitridae) Skopidae (Pandionidae) Secretaries (Sagittariidae) Falcons (Falconidae) Nocturnal birds of prey include representatives of the order of owls (Strigiformes), which include two families: Owls (Strigidae) Barn owls (Tytonidae)

What is characteristic of birds of prey?
a certain set of digestive enzymes necessary for the efficient digestion of animal food, and the corresponding forms of behavior used when hunting various animals (birds, mammals, reptiles, etc.), large wingspan, strongly pointed claws, curved beak, sharp eyesight and good hearing .

Hawks (lat. Accipitridae) - a family of falcon-like birds. They are found on all continents except Antarctica and some oceanic islands, the most diverse and numerous in the tropics. There are cosmopolitan species whose range covers several parts of the world, island forms have a dotted range. They are found in a wide variety of types of landscapes: forests, tundras, steppes, deserts, in mountains up to an altitude of 7000 meters above sea level.
whistling kite

SCOPE (Pandion haliaetus) is the only species of the skopin family - it has a cosmopolitan distribution, occurring near water bodies. It lives in Europe and Asia (except for the tundra, south to Spain, the Mediterranean and South China), North Africa, Australia, North America, and on a number of islands in the Pacific Ocean. In the northern part of the nesting area, the osprey is migratory, wintering in South Africa, India, Indochina, and in the south of North America. The osprey arrives in our country in April, when water bodies are freed from the ice cover, and flies away for wintering in September. Osprey length 55-60 cm, weight 1.3-1.9 kg.
Osprey

The secretary bird, or secretary [(lat. Sagittarius serpentarius) is a bird from the falconiformes order, the only species of the family of secretaries. Her peculiar name comes from the black goose feather feathers on her head that court clerks used to wear in their wigs.
secretary bird

Falcons (lat. Falconidae) - a family of birds from the order Falconiformes (Falconiformes). Contains 12 genera and about 60 species. These include the smallest birds of prey - pygmy falcons, the size of which is in the range from 15 to 19 cm.
caracara

Owls (lat. Strigidae) - a family of birds of prey, belonging to the order of owls. Owls include, for example, long-eared owls, tawny owls, scops and eagle owls. In total, 23 genera and more than 200 species are classified as owls. Most owls hunt exclusively at night or at dusk. They differ from other birds of prey in the absence of a goiter, the presence of long blind intestines. For many peoples, owls are a symbol of wisdom. The owl has always been depicted along with the ancient Greek goddess of wisdom Pallas Athena and the Roman Minerva.
Owl

Barn owls (lat. Tytonidae) are one of two families of owls. The triangular facial disc, tapering downwards, distinguishes barn owls from true owls. The body is slender, the head is narrow and long. All barn owls are nocturnal hunters and feed mainly on small mammals such as mice, shrews, as well as small birds and large insects. To avoid sounds during flight, their feathers have a special fluff, and the feathers themselves have a special structure.

5 Significance of Predators

Are predatory animals necessary for nature?

Predators are nurses. Only sick animals are killed and the rest are kept. Destroy field pests (mice). Skins and fur are used by man. Due to the fact that many animals have good fur, they were mercilessly killed.

Lone hunter. Hunting antelope. Always knocks down the victim with one jump and kills him by biting through the throat. Doesn't eat carrion. Never attacks a person

Is on the brink of extinction

Side 38

Student Snow Leopard

Found in the mountains at an altitude of 3-4 km. Beautiful and strong animal. The fur is spotted, black spots on a silvery white background. The leopard is not a very large animal, its body length is 1.5 meters, and its weight is 30-39 kg like a dog's. Short legs and long very fluffy tail. Hunting mountain goats. The leopard lies in wait for them on narrow mountain paths. Sometimes it follows the same herd on its heels for months. Sometimes it manages with hares, catches a marmot or a bird. The man loves to hunt leopards. There were cases when hunters died falling from a height. Once a leopard killed a hunter by pushing a stone at him. Over the past 20 years, the number of snow leopards has declined markedly.

Carnivores - a detachment of placental mammals11 modern families of carnivores contain about 270 species in 110 genera and are distributed almost all over the world. The vast majority of the members of the order are classic carnivores, preying mainly on vertebrates. Carnivores are sometimes also divided into two groups that differ greatly from each other in their way of life: land predators and pinnipeds.

Many carnivores eat more than just meat. Bears are opportunistic omnivores, and some species, such as the giant panda, even specialize in plant-based nutrition.

Red pandas, badgers, olingos, kinkajou, raccoons, and raccoon dogs also make up a significant, if not the main, part of their diet. Hyenas and canines (wolves, coyotes, jackals, foxes) eat watermelons and melons on melons and fruits that have fallen to the ground

The order of predatory animals is very diverse. Animals vary in size, habitat, modes of movement and other characteristics. Most of the predatory representatives lead a terrestrial lifestyle, but there are also individual representatives, such as minks and otters, living in fresh water, and a sea otter, which is a marine animal.

The animals of this detachment are different in size. The order includes both a miniature weasel and a polar bear. Body length varies from 14 cm to 3 m, and weight from 100 g to 1 ton. Predatory animals are armed with very sharp claws that help them in hunting. Most carnivores have a long tail, except for bears, in which it is hidden under fur. The hairline is well developed. It is different, depending on the type of animal, in density, splendor and color.

For most predators, it is common to eat the meat of animals killed by them, while they do not disdain the remnants of other people's food, carrion, insects and vegetation. Due to the difficulties of regularly obtaining meat, predators have to stock up, but sometimes there comes a time when they have to starve.

Most representatives of the predatory order prefer a solitary or lonely family lifestyle. Animals mark their territory with urine or excrement. The size of the territory depends on the size of the predator, the amount of food needed and the availability of food. Some animals live in packs. The pack consists of united families of parents and their cubs, such a way of life includes wolves and lions. Predatory animals hunt mainly at dusk, at night or at dawn, in places remote from people.

The habitat of the predatory order is very wide. Its representatives can be found all over the globe, except for Antarctica and small oceanic islands. The families of wolf, bear and marten are especially widespread.

Most representatives of the predatory order have practical applications for us. Such animals as sable, otter, mink, arctic fox, leopard, fox, etc., we attributed to animals with very beautiful and lush fur, which is valued to this day. Especially valuable are the skins of animals that lived in the northern latitudes and high mountain regions. Due to the high demand for their skins on the market, people began to breed or acclimatize them in places that are not natural habitat or where they were once exterminated.

Sometimes predatory animals can be epidemically harmful. For example, a wolf, a jackal, a raccoon dog, along with domestic dogs, in some cases are the hosts of the rabies virus and become very dangerous for humans.
