  2. ARTHROPODA • More than 1 million species • The most numerous group of the animal kingdom • A segmented body • The segments are joined into units: • Head • Thorax • Abdomen • The units of some arthropoda can merge

  3. ARTHROPODA • Limbs are segmented • They are changed into mouth organ and feelers on the head • They are used for movement on the thorax • They are used for different purposes on the abdomen – reproduction… • The body is covered by one layer of epidermis – the cells of epidermis segregate a thick cuticila (chitin) • chitin – solid, hard, resistant • The body cover has a function of a skeleton which muscles are set to

  4. ARTHROPODA • An external skeleton must be taken off during the growth • The period of growth is limited • Breathing: • By the whole surface of the body • By gills • By pneumatocysts • By spiracles

  5. ARTHROPODA • Sensorium: • Cone cells and rod cells (chemical and mechanical stimulations) • Eyes (compound, non-compound) • High nerve abilities • instincts • adaptive behaviour • They got into all biotopes

  6. ARTHROPODA • CHELICERATA • TESTACEOUS ANIMALS • TRACHEATA • DIPLOPODA • CHILOPODA • COLLEMBOLA • INSECTA

  7. ARTHROPODA - CHELICERATA

  8. ARTHROPODA - CRUSTACEANS • Fresh waters, salt waters • A stone crayfish • A noble crayfish • A crab • A crayfish • A prawn • They are a part of plankton – cyclopoida, cladocera (water fleas)…

  9. ARTHROPODA-TRACHEATA

  10. ARTHROPODA–TRACHEATA - INSECTA • Head, thorax, abdomen • HEAD: • Antennae, mouth system, eyes (compound, non-compound) • Mouth apparatus– biting, licking, sucking, sting sucking • THORAX: • Three pairs of segmented limbs • Two pairs of wings

  11. INSECTA HMYZ – MOUTH APPARATUS ÚSTNÍ ÚSTROJÍ

  12. INSCESTA – LIMBS HMYZ – KONČETINY G – a walking leg H – a jumping leg CH – a digging leg I – a predatory leg J – a swimming leg K – a swimming leg L – a climbing leg

  13. REVISION: • 1) The body of arthropoda is divided into… • 2) On the skin there is created a solid … • 3) Do arthropoda have an internal skeleton? • 4) How do spiders differ from harvestmen? • 5) Cyclopoida and cladocera are a part of…
