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 SCORPIONES Tropic, subtropic A venom gland on the abdomen An euscorpius tergestinus PSEUDOS CORPIONES In our country A venom gland on the small claws SPIDERS A cephalo thorax and an abdomen Nets An extracorporeal digestion A cross spider A lycosa (a wolf spider) A misumena (a flower crab spider) HARVESTMEN They do not make nets Autonomy (the ability to separate out a part of the body) ACARI Parasites A castor bean tick An itch mite Spider mites

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 MILLIPEDES They live under stones The body is covered by a shell A glomeris A polydesmus CHILOPODA An oblate body There is a pair of limbs from each segment SPRINGTAILS They have a spring system on the abdomen They eat algae, fungi They live in the soil A tomocerus

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 C) biting D) sucking E) sting sucking F) licking

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

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…
