red algae

bryozoans

colonial invertebrates calcareous skeleton

if a lot of bivalves were present what would that mean for the substrate?

usually infaunal meaning there would be very little hard substrate

Nekton

organisms that can move independently of currents

can plankton move independently of currents

no they need currents or other physical forces

phytoplankton are what

autotrophic

zoopkaton are what

heterotrophic think of the hboi tour and how we collected a bunch of baby crabs. Animals

larger than 0.5mm

less than 0.005mm

Chrysophyta

diatoms: silica cell wall. forms fossils or diatomaceous earth

haptophyta

coccolithophores. Think the clivers of Dover. they form chalky plates

dinoglagellata

dinoflagellates. alga that has cell wall of silica common fossil in soik and sediment deposits and culprit of red tide plus bioluminescence

cyanobacteria

blue green algae however its bacteria

Chaetognaths

arrow worm. very fast for seize and predator of zooplankton

pteropods

Mukkucs; very simular to snails

they live in the open ocean

ichthyoplankton

larval fish

epifauna

living on ocean bottom or substrate

infauna

living in the bottom

what are some motile organisms

brittle sea stars, worms, horse-shoe crabs.

fringing reefs

grow near or attached to the shoreline in shallow water

barrier reef

typically grow along outer edges of continental shelves

atolls

circular reefs enclosing lagoons withour a central island. brgin growing upward around seamount

patch reef

are isolated comparatively small reef outcrops usually surrounded by sand or seagrass beds

what do coral need to survive?

a. water clarity and sunlight

b. warm water 20-32 C

c. Oligotrophic water

d. currents

e. all the above

e

branching algae that looks like a wanky tree

halimeda spp.

algae that is straight and kind of looks like when you put you hand spread out

Codium sp

merman's shaving brush. looks like a brush at the end that you put shaving cream on

penicillus pyriformis

mermaids wine cup. Spiral. when you stick it to your nose it shows if you are one with the sea

Acetabularia calyculus

sea pearls. These can get really big and are circular

Ventricaria ventricosa

mermainds fan. this looks like an algae fan

udotea flabellum

what are some important uses for algae?

biofuels, agar, cosmetics, food, clean up

what is a clear difference between algae and sea grass?

algae holds onto something, where as seagrass plants itself (it has roots)
