3 Arthropods Jointed imbs Hard externa skeeton Segmented body Segments are grouped together to form distinct regions, the head, thorax and abdomen. Exampes: insects, crustacea, spiders and centipeds

4 Crustacea Exoskeeton and jointed egs. Two pairs of antennae (sensitive to touch and to chemicas) Compound eyes are made up of tens or hundreds of separate enses Jointed imbs on each segment of the body Exampes: Crabs, prawns and obsters.

5 Insects Large cass of arthropods. Segmented body. Segments are grouped into distinct head, thorax and abdomen regions. Exoskeeton Two pairs of jointed egs Compound eyes Two pairs of wings Exampe: bees, butterfies, mosquitoes, house fies, beetes etc.

6 How insects differ from crustacea? Insects having wings Ony one pair of antennae Three pair of egs No imbs in abdomina segments.

7 Arachnids Body is divided into two regions, the cephaothorax and the abdomen. Four pairs of imbs on the cephaothorax Pedipaps are for reproduction Cheicerae are used to bite the prey Severa simpe eyes

9 Myriapods Miipedes (hebivorous) and centipedes (carnivorous) They have head and a segmented body, which is not divided into thorax and abdomen. Simpe eyes One pair of antennae

12 Vertebrates

13 Fish Basic Facts Fish ive in neary every singe aquatic habitat imaginabe Fish are aquatic vertebrates characterized by fins, scaes, and gis Fish were the first vertebrates to evove. Fish bring in Oxygen rich water through gis and remove oxygen poor water through gi sits Cosed circuatory system Four chambered heart Swim badder contros buoyancy Most are egg aying Most move by contracting opposite musces (S Shaped)

14 Groups of Fish Jawess Fish Have mouths of soft tissue with no true teeth. Have no bones Ony vertebrates with no vertebra coumn as aduts Lampreys, Hagfish Chondrichthyes Skeeton buit entirey of cartiage Sharks, sea rays Osteichthyes Bony Fish Majority of fish fa in this order Carp, sea horse, perch, etc.

16 Amphibians Basic Facts Amphibian = doube ife Live in both water and and Cod booded Four imbs and no scae Most arvae are fishike; aduts are terrestria carnivores Larvae respire through skin/gis; Aduts use ungs First appeared 360 miion years ago Externa fertiization Cosed circuatory system; three chambered heart They have moist skin which hepfu in the exchange of gases with air and water. Exampe: Frog, toads

17 How hind feet in frogs heps in swimming? Hind feet offers a arge surface area to thrust against the water when the anima is swimming.

18 Section 30-3 The Life Cyce of a Frog Adut Frog Young Frog Aduts are typicay ready to breed in about one to two years. Frog eggs are aid in water and undergo externa fertiization. Fertiized Eggs The eggs hatch into tadpoes a few days to severa weeks ater. Tadpoes Tadpoes graduay grow imbs, ose their tais and gis, and become meat-eaters as they deveop into terrestria aduts.

19 Section 30-3 Amphibians means Doube ife as Larvae they ive in aduts they ive on Water Land and have specia adaptations such as Bones that aow for Efficient movement Lungs are Ribs that aow that provide Breathing are air Support and protection

20 Groups of Amphibians Saamanders Long bodies and tais Aduts are carnivorous Usuay ive in moist woods Frogs and Toads Lack tais Frogs have ong egs and are usuay tied to water Toads have shorter egs and not as cosey tied to water

21 Repties Basic Facts A repties have: Dry, scay skin heps prevent oss of body water in dry environments Terestria eggs first animas to deveop amniotic eggs that didn t need to be deposited in water Cod booded Respire using ungs Interna Fertiization; Most are egg-aying Cosed circuatory system They can reguate their body temperature by basking in the sun unti their bodies warm up. Exampe: Lizards, snakes, turtes, crocodie and tortoises

22 Spotted Saamander Poison Dart Frog Fire Beied Toad Caeciian

23 Groups of Repties Lizards and Snakes Have egs & cawed toes (izards) externa ears, movabe eyeids Highy evoved speciaized forms (venom) Crocodies and Aigators Long, typicay broad snout and squat appearance A are carnivorous Protective of young; carry hatchings in their mouth Live in tropics and subtropics Aigators ive in freshwater Crocodies ive in fresh or satwater

24 Cora Snake Sea Turte Gaapagos Tortoise Tuatara

25 Nie Crocodie North American Aigator

26 Birds Basic Facts Neary 10,000 modern bird species Warm booded Birds are cosey reated to repties (scaes on egs) Have outer covering made of feathers, two egs used for waking or perching, and foreimbs modified into wings Feathers separate birds from a other anima species Feathers provide insuation for warmth; can generate on body heat Beak/Bis adapted to type of food they eat Highy efficient respiratory system; ungs ony exposed to Oxygen rich air Interna fertiization

27 Purpe Finch Stork Red-Taied Hawk Emu

28 Mammas Basic Facts First true mammas appeared 220 miion years ago Mammas fourished after dinosaurs became extinct 65 miion years ago Basic characteristics Hair Mammary gands produce mik to nourish young Breathe air Four chambered heart Endotherms can generate own body heat Interna fertiization; care for young
