Kingdom Animalia
~ Characteristics ~
• Multi-cellular
•Eukaryotic with no cell walls
• Heterotrophs (consumers)
•motile
Characteristics Cont.Animal Movement
• Motile, mobile–Most animals are capable of
complex and relatively rapid movement compared to plants and other organisms.
Animal Reproduction
• Most animals reproduce sexually, by differentiated haploid cells (eggs & sperm).
• Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material.
Characteristics of Life
1. Living things are organized.2. Living things are made up of cells.3. Living things metabolize.4. Living things maintain an internal
environment.5. Living things grow.6. Living things respond.7. Living things reproduce.8. Living things evolve.
Animal Sizes
• Animals range in size from no more than a few cells to organisms weighing many tons
a mesozoan blue whale
Animal Habitats
• Most animals inhabit the seas, with fewer in fresh water and even fewer on land.
Animal Cell Diagram
Animal Bodies
• The bodies of most animals are made up of cells organized into tissues.
• Each tissue is specialized to perform specific functions.
Cells->tissues->organs->organ sys >organism
Animal Symmetry
• Describes how animal body structures are arranged
• Allows animals to move in different ways
• Cnidarians and echinoderms are radially symmetrical.
• Most animals are bilaterally symmetrical.
Symmetry:
• The most primitive
animals are
asymmetrical:
No symmetry
Radial Symmetry
• forms that can be divided into similar halves by more than two planes passing through it.
• Animals with radial symmetry are usually sessile, free-floating, or weakly swimming.
Radial Symmetry
Bilateral Symmetry
• Animals with bilateral symmetry are most well-suited for directional movement.
Bilateral Symmetry
~Invertebrates~
• No backbones
• 95% of all animals are in this group
~ Protection and Support ~
–exoskeleton – a hard, waxy coating on the outside of the body
– endoskeleton – support framework within the body
~Invertebrate Phylum Porifera~
• Sponges
• simplest form of animal life
• live in water
• Do not move around
• no symmetry
• 5000 species
~Invertebrate Phylum Porifera~
• Examples: Tube Sponge, Glass Sponge, Sea Sponge
~Invertebrate Phylum Cnidaria~
• Live in water
• Most have tentacles
• catch food with stinging cells
• gut for digesting
~Invertebrate Phylum Cnidaria~
2 different shapes
Medusa - like a jellyfish
Polyp - like a hydra
~Invertebrate Phylum Cnidaria~
• Examples - Jellyfish, Hydra, sea anemones, and corals
~Invertebrate Phylum Mollusca ~
• Soft bodies
• Hard Shells
• Live on land or in water
• have a circulatory system and a complex nervous system.
• Important food source for humans
~Invertebrate Phylum Mollusca ~
Class Gastropoda
–snails and slugs
–may have 1 shell
–stomach-footed - move on stomach
~Invertebrate Phylum Mollusca ~
Class Bivalves
–2 shells hinged together
–clams, oysters,
scallops and mussels
~Invertebrate Phylum Mollusca ~
Class Cephalopods
–squids and octopuses
–internal mantel
~Invertebrate Phylum Platyhelminthes:
worms ~ Flatworms
Example: Planaria, tape wormsFlat, ribbon-like body Live in water or are parasites lives in intestines of host absorbing
foodbilateral symmetryRegeneration- regrow body parts
~Invertebrate : Flat WORMS Cont.~
eyespots detect light scavengers & predators lives in intestines of host
absorbing food food and waste
go in and out the same opening
Examples of flat worms
~InvertebratePhylum Annelida ~
Are Segmented worms Have Body divided into
segments (sections)
–Live in water or underground
–have a nervous and circulatory system
~Invertebrate Annelida Cont~
• Earthworms
• eat soil and breakdown organic matter, wastes provide nutrients to soil
More annelids: segmented worms
• leeches• parasites that feed on blood of other
animals
~Invertebrate
Phylum Arthropod ~ • Body divided into sections/segments
• Exoskeleton – outer – Molt – shed exoskeletons as they grow
• Jointed appendages (legs)
• well developed nervous system
• largest group of organisms on earth
~Invertebrate Phylum Arthropod ~
• Include the classes:–Crustaceans, arachnids,
centipedes, millipedes, and ***Class insecta
• Classified into classes according to the number of legs, eyes and antennae they have.
~Invertebrate Phylum Arthropods~
• Insects- 3 body sections1. Head – antenna
2. Thorax – midsection (wings and legs)
3. Abdomen – (internal organs/structures)
– grasshoppers, ants, butterflies, bees
~ Phylum Chordata: Vertebrata~
