what eats sponges
spongillaflies
sponges are ____ feeders,
they are also friends with algae - why?
filter
sponge symbiosis with algae: algae gives sponge oxygen, sponge gives algae home/protection
cnidaria have cnidocytes. what are these?
specialized cells with filaments to lure prey
hydra:
- habitat:
- _____ in water or _____ to benthic substrates
- they eat _______
- streams, wetlands, lakes
- float in water or attached to benthic substrates
- eat small invertebrates
plathelminthes are _______ and ___ worms and why are they a nusence for humans?
tape and flat worms
and they suck for humans because they’re parasites
nemertea are _______ and live in ______
non segmented worms
marine environments
gastrotricha:
- habitat:
- predator that eats:
- why are they abundant?
benthic, shallow habitat
bacteria, algae, protozoa
eggs resistant to drying/freezing/heat…
which phylum is the zooplankton in?
rotifera
nematoda are the _____ worms that live in ____ habitat
round
extreme
what are the two subsections of phylum mollusca?
gastropoda (snails)
bivalvia (clams)
gastropoda are grazers. what does that mean?
grind surfaces of rock to pull algae of rock
why are gastropoda (snails) important in controlling primary production levels
they eat algae (primary producers), so they control how much algae that grows
T/F: of the phylum mollusca, gastropoda are hosts for many parasites
gastropoda (snails) AND bivalvia (clams) are hosts for parasites
which subgroup of the phylum mollusca is the host to many host-specific parasites
bivalvia (clams)
oligochaetes are part of which phyla, eat _____ and live where?
annelidia (segmented worms)
eat detritus
live in shitty environment: low O2 and pollution
leeches are part of what phyla, eat what and found where
annelidia (segmented worms), eat mollusc/insects/worms, live in slow moving water
bryozoans are sessile and heterotrophs. what does this mean
sessile = attached to substrate
heterotroph = eat suspended food particles
arthropoda have 3 general points/characteristics. what are they
- have 3 body segments
- chitin exoskeleton
- diverse
what are the 3 main subgroups of the phyla arthropoda?
arachnida
insecta
crustacea
arachnida:
- water mites and spiders
- mites live in:
- spiders live:
- mites are _____ and some ______
mites live in fresh waters
spiders live on land beside water
mites are predaceous and some parasitic
insecta:’
- what’s so special about their life cycle?
- can live in ____ or _____ water
- feeding examples
- part of life cycle in water, other part on land
- lentic (not flowing) or lotic (flowing) water
- scrapes, shredders, parasites, predator
crustacea have a cool exoskeleton. what’s it made of
chitin exoskeleton reinforced with calcium
what are the 5 subgroups of crustacea

- food:
- what’s so special about them?
- benthic, in all aquatic places
- eat detritus and algae
- taste yummy to predators
Copepods
- micro-_____
- habitat:
- what’s so special about them?
- micro crustaceans
- benthic or pelagic
- complex behaviours: predator avoidance, mating, foraging
^ COPE-pods know how to cope
Branchipoda
- water ___ and ____
- habitat:
- they don’t like:
- what’s so special about them?
water fleas and shrimps
pelagic zone of lake
don’t like flowing water
predator avoidance by moving to bottom o flake during day so predators can’t see them
Decapoda
- ex.
- highly developed ____
crabs, lobsters, shrimp
chelae (pinchers)
isopoda vs amplipoda
- morphology
- eating habits
- habitat
isopoda are flat and wide

shape and mouthparts
where they live
fish have 3 main sensory systems:
eyes,
chemoreception
lateral line (feel vibrations)
