34. Kingdom Animal:
... is also divided into 9 large groups called Phyla. There are 8 invertebrate phyla and only 1 vertebrate phylum.

35. There is only one phyla of vertebrates, chordates.

36. Phylum #9. Chordates (vertebrates)
Chordates are the last and most complicated phylum to appear on earth. They are divided into 7 classes....
Missing jawless fish

37. From least to most complex:
Fish(3 classes)
Jawless Fish
Cartilage Fish
Bony Fish
Amphibians
Reptiles
Birds
Mammals

38. Class #1-3 Fish 1st animals with bones Cold blooded Breathe with gills
Divided into 3 classes ....

39. Fish (cont.)
The simplest, earliest fish were Jawless Fish(Class#1). They have cartilage bones, no gill covers, and are parasites. Few species remain today, but among them are the:

40. Hagfish

41. Lamprey
mouth
Major Hickey!!

42. Fish (cont.)
The next fishes to evolve were the Cartilage fish (Class#2). They still had cartilage bones and no gill covers, but were predators and able to seek out food.

43. Shark

44. Rays

45. Fish (cont.)
The most complicated group of fish is the Bony Fish(Class#3). They have real bones, gill covers, swim bladder and dominate the fish class today.

46. Walleye

47. Sunfish

48. Seahorse

49. Porcupine fish

50. From least to most complex:
Fish(3 classes)
Jawless Fish
Cartilage Fish
Bony Fish
Amphibians
Reptiles
Birds
Mammals

51. Class#4 Amphibians
The next bony animals to appear on earth moved on to the land for part of their life. They start in the water, move to land as adults, and back to water to reproduce.

52. Amphibians spend their
early days in water.

53. Amphibians absorb their
tail and develop lungs
instead
of gills.

54. Leopard Frog

55. Tree Frogs

56. Toads

57. Salamanders

58. From least to most complex:
Fish(3 classes)
Jawless Fish
Cartilage Fish
Bony Fish
Amphibians
Reptiles
Birds
Mammals

59. Class#5 Reptiles
The 1st class of chordates to live mostly on land, they have dry, scaly skin, lay their eggs on land and ruled the earth for a while but are still cold blooded. Reptiles are divided into 4 groups...

60. Class#3 Reptiles (cont.)
Snakes species left
Lizards species left
Turtles- only 200 species
Crocodilians- 25 species remain

61. Reptiles were the first
animals to lay
shelled
eggs.

62. Chameleon

63. Timber Rattlesnake

64. Boa Constrictor

65. Painted Turtle

66. Desert Tortoise

67. Sea Turtles mate only
once every 30 years and
live for 150 years!!

68. Alligator

69. Crocodiles really need
braces!!

70. Gavials

71. From least to most complex:
Fish(3 classes)
Jawless Fish
Cartilage Fish
Bony Fish
Amphibians
Reptiles
Birds
Mammals

72. Class#6 Birds
Descended from lizards, Birds were the 1st warm blooded creatures on the earth. That, plus feathers and the ability to fly allows them to flourish today!!

73. Although warm blooded,
birds eggs are vulnerable!

74. Swans

75. Birds of prey
have
keen
eyes
and
ears.

76. Not all birds fly!

77. Many male
birds are
colorful to
attract females.

78. From least to most complex:
Fish(3 classes)
Jawless Fish
Cartilage Fish
Bony Fish
Amphibians
Reptiles
Birds
Mammals

79. Class#7 Mammals
Not only were they warm blooded, but they keep their young inside the female until born. They still dominate the animal kingdom, the Mammals.

80. Female mammals have milk
(mammary)
glands.

81. Mammals are warm blooded
and live in a variety of climates.

82. Some
in very
hot
climates
African
Elephant

83. Some mammals even live

84. Mammals are also
adapted to
eat in a
variety of
ways.

85. An average bat

86. Some mammals have hoofs.
