INVERTEBRATES: WORMS EARTHWORMS The family of earthworms consists of almost 170 species, and belongs to the type of annelids. All earthworms similar in lifestyle. They live in damp places, swarm underground, in cold and drought they go deep into the ground. After heavy rains due to lack of air, earthworms are forced to rise to the surface. They feed on decaying plant remains and soil microorganisms. There are especially many earthworms in the soil of gardens, orchards and other soils, where their number can reach 400 pieces per 1 m of land. Size from 8 to 30 cm.

Cephalopods octopus, cuttlefish and squid There are 600 species of animals belonging to the class of cephalopods. These are mollusks with a clearly distinct head and a crown of eight or ten tentacles surrounding the mouth. All cephalopods are predators. The main food is fish, crabs, and small mollusks. INVERTEBRATES: molluscs

Cephalopods octopuses, cuttlefish and squid Cephalopods have not one, but three hearts: one head and two gills. And their blood is unusual - blue! Dark blue when saturated with oxygen, and pale with carbon dioxide. INVERTEBRATES: mollusks A cephalopod moves by sucking in water (it also supplies it with oxygen) and forcibly pushing it out through a funnel. The active work of the natural jet engine allows them to reach speeds of more than 30 km per hour. The meat of squid, octopus is a human food product. Their fishing is especially developed in Japan, China and Korea.

Octopuses do not live long. Most species live only up to 2 years. Octopuses stop feeding after mating, and go without food for several months. Octopuses do not have any bones or protective bodies. The only hard part of the body is the parrot-like beak. The whole body is unusually soft, flexible and elastic. It allows the octopus to penetrate the narrowest cracks and holes in the rocks. The only limitation is the beak. One of the most interesting features octopus is its ability to change the color of the body, allowing you to instantly copy the colors of surrounding objects.

INVERTEBRATES: molluscs bivalve molluscs fresh waters. Man uses some types of bivalves for food (mussels and oysters), as a source of material for jewelry (mother-of-pearl and pearls), as souvenirs or even money. The body of these mollusks is covered with a hard bivalve shell. It opens with an elastic ligament that connects the flaps on the dorsal side. The valves are closed with the help of two closing muscles running across the body at the anterior and posterior ends. About 20,000 species of mollusks belong to the class of bivalves.

"Butterfly Lesson" - Butterfly came out immediately. If we were allowed to live without encountering difficulties, we would be deprived. Sometimes it is effort that we need in life. On the path to virtue. And life gave me the brain and muscles so that I could work. I asked for blessings... and life gave me opportunities. We could never fly.

"Lesson Animals" - At an early age they live in water and breathe with gills. Acquaintance with new theme. Systematization of knowledge. SPb APPO Center for Informatization of Education. Herbs. Let's continue filling in the table: Insects. Write down the answers in 3 columns: Trees. Red tail Covers traces. They breathe oxygen dissolved in water. The body is covered with feathers.

"The life of animals in winter" - The life of animals in winter. How do animals prepare for winter? January, our people say, is the beginning of the year, the middle of winter. Academic subjects: The world. Constipated water - ice. Grasses, bushes and trees froze. The fundamental question is: how nature changes in winter. Wolves, foxes prey on mice, hares. Blizzards and blizzards came flying in February, they run along the trail, but there is no trace.

"Predatory animals" - Eagle. Predatory mammals. Fragment of a film about a predator. Predatory fish. Herbivorous and carnivorous animals. Lion and lioness. Hare.

"Animals and Plants of Russia" - Animal and vegetable world Russia. Deserts and semi-deserts. Steppes. In semi-deserts and deserts temperate zone conditions are less favorable for the existence of plants and animals than in the steppe, therefore, as in arctic deserts, a continuous cover of vegetation is not formed here. Desert vegetation is well adapted to drought: the leaves of many plants have turned into thorns, evaporating a minimum of moisture, the roots are branched and very long.

"Ancient Animals" - Ankylosaurus. Ceratosaurus. Completed by: a student of grade 3 G of the multidisciplinary gymnasium No. 12 in Chita Mikhalev Yuri. Introduction. Thank you for your attention! The dinosaur's body is covered with a thick shell. Dinosaurs. Presentation to research work on the topic "Prehistoric animals" (Dinosaurs). Stegosaurus. Allosaurus. The first remains were discovered in the 19th century.

MKOU Vasilievskaya secondary school of the Safonovsky district Theme of the lesson: "Invertebrates" Biology teacher: Berkunova Elena Anatolyevna 2016

The purpose of the lesson: to introduce students to the sub-kingdom Multicellular and invertebrate animals; To form students' interest in the study of the animal world.

At the beginning of the 19th century, the French scientist Jean-Baptiste Lamarck divided the animal world into two main groups - invertebrates and vertebrates. Invertebrates are a large group of animals that do not have an internal skeleton, the basis of which is the spine. Invertebrates make up approximately 95% of all living animal species. They have a different structure. Many of them adapt well to changing living conditions.

Sponges Sponges are predominantly marine animals attached to the bottom and underwater objects. The body of sponges resembles a glass filled with pores. At the free end of the body there is an outlet - the mouth.

Coelenterates Coelenterates - predatory aquatic, mainly marine with a sac-like body. At the front end of the body is a mouth opening surrounded by tentacles. jellyfish hydra coral polyps

Echinoderms Echinoderms are inhabitants of the seas, capable of slow movement. The sizes of echinoderms range from a few millimeters to 1 m. Holothuria sea urchins starfish

Mollusks Mollusks are terrestrial and aquatic animals with a soft non-segmented body covered with a skin fold - mantle. The body of mollusks consists of a head, trunk and legs. Most molluscs have a shell. mussels cuttlefish squid octopus snail oysters

Arthropods Arthropods are the most large group animals that inhabit our planet. Outside, their body is covered with a hard cuticle. It consists mainly of the organic matter of chitin and forms a shell that protects the body and acts as an external skeleton. Arthropods include crustaceans, arachnids and insects.

Crustaceans Crustaceans are mostly aquatic animals. Their body consists of a head, chest and abdomen. Respiratory organs gills. crab shrimp lobster

Arachnids Arachnids are basically terrestrial arthropods that have eight legs. The body of arachnids consists of a head, thorax and abdomen. mite harvester scorpion

Insects Insects are arthropods that have six legs and respiratory organs - the trachea. The body of insects consists of three sections: head, thorax and abdomen. Most insect species have developed wings. The world of insects is most diverse in the tropics.

Thank you for attention

Jellyfish have relatives - corals The secret of corals is that we most often see a whole coral house, more precisely, their common skeleton. And in this common skeleton, as in apartments, tiny transparent numerous corals live. Corals are similar to jellyfish: they are also transparent and have poisonous tentacles. transparent and with poisonous tentacles. You will see them on the next slide. staghorn coral

Sponges are not predators. They pass, pump water through themselves and find in it everything that can be eaten: pieces of algae, the remains of someone else's food, and so on. And everything that you can eat is left for yourself, and the rest comes out of the sponges along with the water. It's like a water filter (although a real filter doesn't eat anyone, of course). Sponges for such nutrition are called filter feeders.

The most famous worm is the earthworm. It lives in the soil and crawls out of its burrows after rain. The earthworm is very useful. It improves the soil. With its help, the soil becomes more fertile, that is, plants grow better on it and we get more harvest!

Mollusks are not only gastropods, like snails or slugs. Clams are bivalve! Such molluscs are placed in shells from two halves - from two valves. For a shell of two wings, they were called bivalves. Bivalves are oysters and their relatives. Bivalves are filter feeders, that is, they eat the same way as sponges. filter feeders

Since ancient times, bivalves have been highly valued for the pearls they sometimes make in their shells. Yes, even without pearls, the shells of bivalve mollusks shimmer with mother-of-pearl. Jewelry is made from pearls and mother-of-pearl. In the photo - galiotis, the builder of a very beautiful mother-of-pearl shell

Who is it floating? Yes, it's an octopus! Octopuses and their relatives are also mollusks. Only they are called cephalopods. And relatives of octopuses are squid and cuttlefish. They are all good hunters. cephalopods very fast, strong and smart! Large octopuses are called octopuses.
