Kingdom Animalia

Kingdom Animalia

Char: Domain Eukarya, Opisthokonta, Kingdom Animalia, and Multi Cell, Ingest food and digest internally, movement at some stage, most invertebrates, most larvae stage, most have complex tissues
Synap: Unique Cellular junctions and Matrices, (Collagen/Proteoglycans=Matrix and Desmosomes/tight junctions=cell junctions)

Bilateral Symmetry

One plane through center of organism

Radial Symmetry

Multiple planes of symmetry from center out

Ectoderm

Outside of body (Skin/Nervous System)

Endoderm

Innermost (Digestive tract/urinary tract)

Mesoderm

Middle layer (Body Cavity with organs, muscles, skeleton) Tripoblast only

Acoelmates

Flatworms
No Selom, ancestors had them

Complete Coelomates

Mollusks, Anthropods, etc
Body Cavity lined with mesoderm (More complex body)

Pseudocoelmates

Body cavity partially lined w/ mesoderm (Limits complexity/movement)

Phylum Cnidaria

Jellyfish/Corals/Sea Anemones/etc
Char: All Euk, Opis, Animal King, Radial Symmetry, Dipoblast (2 layer tissue), no brain but evidence of sleep, mostly muscles/nerves, most 2 life stages (Medusa/Hydra or Polyp), blind gut (one opening for mouth and anus)
Synap:Cnidocytes: Stinging cells
Mesoglea: Proteinaceous gel/jelly layer btwn endo
Nerve net: web of nerves across body

Phylum Cnidaria Eco/Econ

Tropical Oceans: Coral reefs (Hard corals from CaCo3 from h20) which is habitat for many species/tourism/fishing
Monterey Bay: No reefs but lots of pelagic jellies
Major Impact from climate change: Coral Bleaching: normally dinoflagellates(zookontheia) live in coral/feed on w/ photosynthesis but warm temps trigger immune response and kicks out dinoflagellates
Sea Anemones (Major Pred)

Protosomes

Blastopore becomes mouth 1st
Mesoderm splits to form Coelum

Deuterostomes

Blastopore becomes mouth 2nd/anus first
Mesoderm pinches off to form Coelum

Gastrulation

Gut formation from blastospore

Body cavity

Coelom formation from mesoderm

Superphylum Protostomia/Protosomes

More than 95% of animal species
Synap: Anterior (front) brain that surrounds the gut
Central nervous system on ventral/stomach side

Lophtrochozoans

Major protostome group
They have lophophor(Ciliated hair tentacle for food) or/and Trochophore larvae (ciliated larvae that swims)

Ecdysozoans

2nd Major protostome group
Sheds exoskeletons like anthropods shed outer body to grow

Phylum Platheminthes (flatworms)

Plat means flat
Blood/liver flukes, trematodes, tapeworms, planarians
Char: D. Euk, K Animal, Protostome, Opisthokonta, Very Flat (Sometimes 1 cell thick), blind gut (mouth=mouth and anus)
Synap: Secondarily evolved the loss of coelom (body cavity) but ancestors had
Due to thinness: Gas exchange directly through host/environment

Phylum Annelida (Segmented worms)

Earthworms/Maine polychaetes:leeches
Char:D. Euk, K Animal, protostome, Opisthokonta, one way gut (mouth/anus seperate), closed circulatory system, complete coelum
Synap: Repeated organs in each segment
Circumvention and Longitudal muscles around ceolum for complete movement

Phylum Molluska

Mollsuks/shellfish/Squids/Slugs
Char:D. Euk, K Animal, protostome, Opisthokonta, one way gut(sep mouth and anus), most open circulatory but cephalopods=closed circulatory system)
Synap: Mantle: Dorsal tissue that secretes protective layer (Like Shell)
Muscular foot: Special muscle for locomotion
mantle cavity: Central area of organs (blob)

Phylum Molluska Eco/Econ

MMajor predator/herbivore/filler feeder
Intertidal domination:mollusks
Medical research such as cone snail toxin
Important food like clams oysters muscles
Smart invertabrates

Phylum Annelida Eco/Econ

Terrestrial (Earth Worms) that are decomposers and build soils
Marine: Predator/Filler feeders
Freshwater: Ectoparasites like leeches, anticoagulant blood, medical research

Phylum Platyhelminthes Eco/Econ

Most are major parasites
Some tiny free living predators
