- Hollow case
- Phylum Cnidaria ( Jellyfish, Corals, Anaenome)
- Radial Symmetry
- Sessile Polyps
- Mobile Medusa
- Diploblastic
- Gastrovascular cavity
- Hydrostatic Skeleton
- A form of skeletal structure that forms due to the opposing force created between the contractile muscles of a creature and the hydraulic pressure created within it's gastro-vascular cavity
- A form of skeletal structure that forms due to the opposing force created between the contractile muscles of a creature and the hydraulic pressure created within it's gastro-vascular cavity
- Hydrostatic Skeleton
- Radial Symmetry
- Triploblastic Development
- Bilateral
- 3 Types
- Acoelomates
- Solid mass of tissue
- Lack coelom and body cavity
- Solid mass of tissue
- Psuedocoelomate
- Body cavity
- Only lined by mesoderm on one side
- Body cavity
- Coelomate
- True coelom
- Lined on both sides by mesoderm
- Endoderm and ectoderm lined by
- Endoderm and ectoderm lined by
- True coelom
- Acoelomates
- 3 Germ Layers
- Endoderm
- Ectoderm
- Mesoderm
- Increase size
- Hydrostatic cavity
- Cushioning organs
- Ciculate metabolites
- Increase size
- Endoderm
- Bilateral
- Phylum Platyhelminthes (Flatworms)
- Bilateral and triploblastic
- Acoelomate
- Locomotion by cilia and muscles
- Limited cephalisation
- Bilateral and triploblastic
- Phylum Annelida (Segmented Worms)
- Bilateral, triploblastic, coelomate
- Able to suspend complex organs
- Able to suspend complex organs
- Segmented Body
- Cephalsiation
- The concentration of sense organs, nervous control
- The concentration of sense organs, nervous control
- Locomotion
- Longitudinal muscles
- Circular muscles
- Contraction of muscles lengthens segment
- Act on hydrostatic skeleton
- Contraction of muscles lengthens segment
- Longitudinal muscles
- Bilateral, triploblastic, coelomate
- Phylum Nematoda (Roundworms)
- Bilateral, Triploblasctic, Psuedocoelomate
- Exoskeleton
- Cuticle
- Keeps pressure on coelomic fluid - no circulatory muscles required
- Keeps pressure on coelomic fluid - no circulatory muscles required
- Cuticle
- No circulatory, excretory or respiratory systems
- Locomotion
- Undulations
- Longitudinal muscles only
- Undulations
- Bilateral, Triploblasctic, Psuedocoelomate
- Phylum Arthropoda (Crustaceans, millipedes, insects
- Bilateral, triploblastic, coelomates
- Most diverse range of species
- Exoskeleton
- Tough, non-cellular, secreted from epidermis
- Provides protection, reduces effects of evaporation, muscle support
- Costly to produce, vulnerable during malting, limits size
- Tough, non-cellular, secreted from epidermis
- Appendages
- Adaptations (e.g. insects have mouth
- Articulated (e.g. flexor-extendor muscles
- Adaptations (e.g. insects have mouth
- Terrestrial adaptations
- Trachea and book lungs for gas exchange
- Impermeable cuticle
- Exoskeleton
- Adaptable mouth parts due to the different food sources
- Trachea and book lungs for gas exchange
- Bilateral, triploblastic, coelomates
