Metazoa, Opistokonths (common ancestor protist) - Coggle Diagram
Metazoa
blastula, (radial cleavage (even layers))?
asymeterical gutless animals, aquiferous system of branched water canals, differencited cells but no muscels , spicules, sessile, larvie mobile, budding or sexual(heramprodites)
Aquiferous system: flows into numerous incurrent pores (ostia) and out through excurrent pores (oscula) by coanocyte flagella (like collar cells)
Porifera (sponge)
calcareous sponges (calcium carbonate)
glass sponges (silica)
demosponges (silica) (most common)
extracellular digestion in gut, complete one way gut, diploblasty, radial symmetry, nerve net and simple musculature
cnetophoe
extracellular digestion in gut, diploblasty
triploblasty (formation of mesoderm), bilateral symetery, cephalization, anterior/posterier end, (coelum opening inside mesoderm)
Bilateria
blastophore becomes mouth, mesoderm starts to form near lip.
protozomes
spiral cleavage, trochaphore larva
1 more item...
Ecdysozoa
2 more items...
blastophore --> anus, enterocoelous (2 coelum cavities)
deutrosomes
radial symmetry (independent from cnetophores etc becase larva is bilaterally symmetrical
2 more items...
notochord
1 more item...
radial end, incomplete cut, tentacles around oral end, grastrovascular cavety, extracellular digestion in gut which is compelted intracellularlly, photosytheos enegry via symbiosis
cnidarians
diversity
cubozoa (box jelly) toxic sting - have eyes with cornea lens retina (but no brain?)
syphozoa - sea jelly
hydrozoans (hydra)
anthazoa (no medusa stage) coral sea anemones, sea fans
asexual polyp & seuxual medusa (one form is often lost - other form must prodcue gametes)
body forms: polyp sessile & medusa motile, cnidocyte (stinging cell)
placazoans
diplontic life cycle, multicellular, heterotrophs, food ingested, disticncitve male gametes, zygote--> blastula (--->gastrula), distinctive cell junctions, collegen and proteoglycan in extracellular matrix
Opistokonths (common ancestor protist)
choanofagulates
animals (metazoa)
fungi
