• Anne lida
• Arthropoda
• Mollusca
• Echinodermata
• Chordata

PORIFERA

• Consisting of organisms commonly known as sponges, name means pore-bearers
• Represent the least evolutionarily advanced group
• Sponges are classified as animals because they are multicellular,heterotrophs and have no cell wall.
• Maintain homeostasis by diffusion
• Sponges have no true circulatory system water is used for circulation dissolved gasses are brought into the cell metabolic waste are brought in through diffusion.
• Porifera's reproduce sexually and sexually. They use egg and sperm at different times
• Porifera's have structures called spicules which is a fine skeletal mesh that has glass like features. Very sharp shards of glass
• Porifera's protect themselves from the environment by their sponges closing their pores.
• Examples include Bath sponge, Finger sponge and basket sponge

CNIDARIA

• Soft bodied carnivorous animals that have stinging tentacles arranged in circles
• Have basic forms of muscle to move around but no heart or brain
• Get nutrients through diffusion of the digestive chamber
• Produce sexually involves polyp and medusa stages of life cycle
• Cnidarians have stinging cells called nematocysts on their tentacles
• Examples medusoid jellyfish, polypoid jellyfish, ctenophore

PLATHELMINTHES

• A flat worm bilateral symmetry and a soft flattened body
• Maintain homeostasis through their hydro skeleton and three layers of skin
• Get nutrients directly from the host they digest
• They reproduce by asexually, have egg and sperm
• Have bad eyesight but can sense good places to hide
• Do not have digestive or nervous system, but have hooked fangs on their mouth
• Examples New Zealand flatworm, Lancet liver fluke and the pork tapeworm

NEMATODA

• Phylum of worms that are parasitic and decomposers
• To maintain homeostasis they take oxygen through their skin, but have no respiratory system
• Nematodes can be herbivore, carnivorous and parasitic when acquiring nutrients
• Nematodes go through sexual reproduction
• Defend themselves through their stylet, a sharp piercing in the mouth
• Nematodes can undergo cryptobiosis a state of live in response to environmental conditions
• Examples Meloidgyne incognita, Ascaris lumbricoides, hook worm
