Kingdom Animalia
Embryonic development
Types of Symmetry
Phylum Porifera“Pore
Bearers”
Symmetry Asymetrical
Reproduction Asexual: budding/fragmentation
Sexual: hermaphrodites
Evolutionary Milestone multicellularity
Circulatory System Diffusion
Unique Characteristic sessile
regeneration
Importance Food chain
Absorbent qualities
Cnidaria“Stinging Creatures”
Symmetry Radial
Reproduction Asexual: budding
Sexual: hermaphrodites
Evolutionary Milestone Tissues (no organs)
Circulatory System Diffusion
Unique Characteristic Stinging cells: cnidocytes
Tentacles
Importance Edible
Protect shorelines
Habitat for others
Coelm: body cavityFluid filled space in multicellular
animals• Coelomate animals: true cavity: with a complete lining
called peritoneum derived from mesoderm
• Pseudocoelomate animals have a pseudocoel: – “false cavity”– tissue derived from mesoderm only partly lines the fluid filled
body cavity of these animals. – All pseudocoelomates are protosomes
• Acoelomate animals, like flatworms, have no body cavity at all. Organs have direct contact with the epithelium.
Platyhelminthes“Flat worms”
Symmetry Bilateral
Reproduction Asexual
Sexual: some are hermaphrodites
Evolutionary Milestone Cephalization: bilateral symmetry
Circulatory System Diffusion
Unique Characteristic acoeloms
Importance Cause diseases
(if wade in water larvae bore thru skin to blood vessels)
Nematoda“Round Worms”
Symmetry Bilateral
Reproduction Sexual
Evolutionary Milestone False Body cavity
Pseudocoelm
Circulatory System Open: fluids circulate within body cavity
Unique Characteristic Tube within a tube
Importance Cause diseases
parasitic
Circulatory System
Mollusca“The Mollusks”
Symmetry Bilateral
Reproduction Sexual
Snails: hermaphrodites
Evolutionary Milestone Coelom: true body cavity
Circulatory System Open: 3 chambered hearts
Closed: octopus and squid
Unique Characteristic •Radula•Mantle
Importance Food chain: edible
pearls
Toothlike scraping device
Annelida“Segmented Worms”
Symmetry Bilateral
Reproduction Hermaphrodites
Evolutionary Milestone Segmentation
Circulatory System Closed
Unique Characteristic Ganglion: primitive brain
Organ systems
Importance Medicinal purposes
Fertilize soil and creates air spaces
Arthropoda“BUGS”
Symmetry Bilateral
ReproductionSexual
asexual
Evolutionary Milestone Jointed appendages
Circulatory System Closed
Unique Characteristic Jointed appendages
Exoskeleton
Importance Food
Causes disease or transmits
Food chain
pollinators
Echinodermata“spiny skinned”
Symmetry Larvae: bilateral
Adults: radial
Reproduction Sex: gonads
Evolutionary Milestone Deuterostome
(Pattern of embryonic dev. Where anus forms @ the blastopore)
Circulatory System Closed
Unique Characteristic Tube feeders
Regenerate “arms”
Importance Food chain
