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

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

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

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

ARTHROPODA•CHELICERATA•TESTACEOUS ANIMALS•TRACHEATA

▫DIPLOPODA▫CHILOPODA▫COLLEMBOLA▫INSECTA

ARTHROPODA - CHELICERATA

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)…

ARTHROPODA-TRACHEATA

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

INSECTA HMYZ – MOUTH APPARATUS ÚSTNÍ ÚSTROJÍ

INSCESTA – LIMBS HMYZ – KONČETINY

G – a walking leg H – a jumping legCH – a digging legI – a predatory legJ – a swimming legK – a swimming legL – a climbing leg

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…
