(Density of organisms - Density of water)/(surface
sinking rate
resistance of organism x viscosity of water)
Which aspects of the Density & surface resistance of organisms
sinking rate can be
altered?
~Substitute heavy ions with lighter ones ~Developing
What are some ways flotation mechanisms ~Accumulate oils and fat ~Have
organisms can decrease a cartilaginous skeleton ~Increase surface resistance
their density? of body ~Be small ~Learn how to swim ~Reynolds
number
~GAS/FLUID-FILLED FLOATS: some cnidarians secrete
gases to create little air sacs that can deflate in the
What flotation event of an attack on the surface ~SWIM BLADDER:
mechanisms do various gases are secreted into the bladder at the same
organisms use? pressure as the feeesh to maintain buoyancy ~BE OILY:
like sharks, keeping oil in the liver determines
buoyancy because its less dense than seawater
What types of organisms ~Benthic species, such as flatfish ~Highly migratory
don't need swim species that need to move quickly, such as blue fin
bladders? tuna
How can an organism ~Flattened body shape & appendages ~Have
increase its surface spiny/spiky projections to increase surface area but
resistance? not volume ~Be super small!
What are ways to find ~Build a collection device/filter ~Have the capability
enough food to eat and to degrow during periods of starvation ~Be big in size!
grow in the epipelagic ~Hunt in groups (cooperative hunting) ~Stay with your
zone? food ~Know where your food will be
