Characteristics of Animals
1) Heterotrophs, Motile/mobile, multicellular, sexual reproduction, adult is diploid
invertebrates lack what?
endoskeleton
5 ways to classify?
levels of organization, Type of body plan, type of coelom, type of symmetry, segmented or not
3 levels of organization?
cell level, tissue level, organ level
two germ layers have?
endoderm and ectoderm
3 layered germ has?
endoderm, ectoderm and mesoderm
two types of body plans
sac plan and tube within a tube plan
sac plan is
organisms have a incomplete digestive system
tube within a tube plan is
organisms with a complete digestive system, food enters and waste exits through separate openings.
3 types of coelom
true coelom, pseudocoelom, and acoelomate
true coelom have?
internal body cavity is completely lined with mesoderm
pseudocoelom have?
incompletely lined with mesoderm
acoelomate have?
have mesoderm but no lined body cavity
types of symmetry?
radial, bilateral, biradial, Asymmetry, spherical
radial symmetry is?
animal is organized circular to the center point and all body appendages are arranged around the center point. (Octopus)
Bilateral symmetry is?
equal right and left half if divided down a midline
anatomical terms that describe the relative location of body parts
Anterior, posterior, dorsal, and ventral
protostomes and deuterostomes mean what? and what form of symmetry uses them?
Pro - “Mouth 1st”, Deutero - “Mouth 2nd”; Bilateral symmetery
A symmetry
the body has no particular symmetry
Phylum Porifora means
“Pore Bearing” (sea sponges)
spicules means
“little spikes”
sessiles are?
attached directly at the base
sea sponges are what kind of reproduction?
A sexual (Budding) and sexually (egg and sperm)
Phylum Cnideria means?
“stinging cells” (sea anenome aka jellyfish, corals) (flowers of the sea)
Phylum Platyhelminthes means?
“Flat worms” (planarian, flukes, tape worms)
Platyhelminthes have what kind of sex organs?
male and female sex organs, cross fertilize
Phylum Nematoda means
“Round worms”
a nematoda example would be?
Ascaris lumbricoides
Hook worms, pin worms, and heart worms are what kind of Phylum?
Nematoda
Phylum mollusca means?
soft body (have shells to protect)
Phylum Mollusca have 3 body parts?
Visceral Mass (Internal organs), Foot (Mobility), and Mantle (covers visceral mass and produces shells)
classifications for Mollusca Phylum?
Gastropoda (stomach footed; snails), Cephalopoda (head footed; squid and octopus) and Bivalvia (two shell ; oysters and clams)
Bivalvia hold the two shells together with what muscle? what kind of circulatory system do they have?
adductor muscle (hatchet footed) they have a closed circulatory system so they move slow.
Phylum Annelida
“segmented worms”
Phylum Annelida classifications
Polychaeta, oligochaeta, Hirudirea
what are Parapedia?
Paddle like setae for movement; setae are bristles for movement
example of Oligochaeta
earthworm
what is a clitellum
reproductive organ, they fuse together
ganglia means
nerves
brain
cerebral ganglion
castings
earthworm poop
earthworms have 5 hearts called
aortic arches
Phylum Arthopoda means
“Jointed foot” made of chitin (exoskeleton)(hard flexible protein)
molt
shed exoskeleton and regrow
3 body region in Arthropoda are?
head, thorax and abdomen
class crustacea are
(yummy) shrimp, crawfish, rollie pollies)
in the class crustacea the cephalothorax is?
the head and thorax
the tail end in the crustacea class?
uropod (telson is the center bottom part of the tail)
entomology is the study of?
insects
metamorphosis is?
the change in shape of organisms as it matures into an adult
class Arachnida are?
spiders, scorpions, ticks and mites
Arachnologists are
scientists that study spiders
ticks feed on
blood
mites feed on
vertebrate skin
Phylum Echinodermata means
Marine animals
Echinodermata endoskeleton consist of
spines and plates
examples of Asteroidea
starfish
characteristics of Asteroidea
move using water vascular system, tube feet, eye spots, sexual and A sexual, spawning - release egg and sperm into the water, regeneration - fragment of the body can regrow as long as central disc is attached.
vertebrates have?
flexible vertebral columns, segmented (repeating vertebra), ears (hearing), equilibrium (balance), complete digestive system, closed circulatory system (blood vessels), separate sexes that carry out sexual reproduction.
what is the class Agnatha?
“jawless fish” lampreys and hagfish
lampreys do what to other fish?
attach and suck their blood
hagfish do what to other fish?
feed on dead fish
