THE ANIMAL KINGDOM
VERTEBRATES: Animals with true backbones (PHYLUM
CHORDATA)
Science AHSGE Standard III-3, part 2
Kingdom Animalia All vertebrates have
bilateral symmetry All vertebrates are
sexual
Multicellular with true tissues
Specialized eukaryotic cells
Muscular/nervous systems unique to animals
Have their own means of locomotion
Consumers- ingest food
1,326,239 classified species
9,812,298 total species
Fish Aquatic/marine Fins- Projections that allow for turning and
balance Swim Bladder- Sac-like organ that holds air
for floatation Gills- Remove oxygen from water Two-chambered heart External fertilization Differentiated by skeleton and/or jaws
Class Osteichthyes (Pisces): Bony fish
Catfish * Red snapper
Giant Asian catfish
Class Chondrichthyes: Cartilagenous fish
Great white shark
Class Chondrichthyes: Cartilagenous fish
Skate
Sting ray
Class Agnatha
Jawless fish Many parasitic
Class Amphibia Smooth moist skin Mucus secreting- Chemical defense Three chambered heart Some skin breathing Two life stages: water and land
– Born with gills– Develop lungs later in life
External fertilization
Class Amphibia Poison dart frog
Example: Warning coloration
Marble Salamander
Class Reptilia Dry, scaly skin Many have claws and fangs
(mechanical defense) Amniotic egg- soft, leathery shell Three chambered heart Internal fertilization Most give no parental care
Class Reptilia Left- Coral snake
– Example: Warning coloration
Right- Scarlet king snake– Example: Mimicry
Class Reptilia Alligator
Crocodile
Giant Croc found in New Orleans after hurricane
Class Reptilia
Turtles
Class Aves Covered with feathers Feathers serve as insulation/flight Hollow bones Beaks are an adaptation to food sources Hard, calcium-enriched shell; some spotted
for camouflage Four chambered heart Internal fertilization
Class Aves Bald eagle
Gray heron
Class Aves Ostrich
Penguins
Class Mammalia Covered in fur Females produce milk for the young Parental care for young Internal fertilization Four chambered heart

Class Mammalia
Order Marsupials Tasmanian devil
Class Mammalia Order Placentals
– Young fully develop inside the mother in a sac-like organ called the placenta

see at night Humpback whales
– Baleen- Device in a whales mouth used to filter food parties
Class Mammalia Order Placentals
