Adaptations
why are some deep sea animals translucent/lacking pigment
because there is no sunlight, they do not need pigment for UV protection
Hammerhead sharks and sea angels
twilight zone/mesopelagic
what colors are absorbed by the ocean (hint: not reflected)
red, orange, yellow, green, NOT BLUE
Deep sea animals have swim bladders
what TERRESTRIAL animal gives off bioluminescence?
firefly!
why do some deep sea animals have long mucus covered appendages/filaments
(bonus points if you name some animals that have this adaptation)
to accumulate marine snow (lack of food)
(vampire squid + 50)
comb jelly and chiton
trench - hadal zone
what is the section of the electromagnetic spectrum that we can SEE color with?
the visible light spectrum
elephant seals dive to the bathypelagic zone
TRUE - Elephant seals swim deep into the mesopelagic (twilight) zone and sometimes into the bathypelagic (midnight) zone of the ocean.
what adaptation is specific to the sunlight zone?
COUNTERSHADING
why do animals in the midnight zone use bioluminescence?
DOUBLE JEOPARDY (what is one negative effect that bioluminescence can have?)
- hunt/lure
- communicate/find mates
- defend against predators
(DJ ANSWER: clear animals that consume bioluminescent animals can become a target!)
blue ringed octopus
sunlight zone
phytoplankton + fungi
the reaction that creates bioluminescence generates heat (bonus points for how much thermal energy within 1-100% range)
NO it is a cold light reaction
(20% thermal energy +200pts)
what was johns favorite deep sea animal?
COLLSAL SQUID
which zone do we start seeing larger eyes as an adaptation?
twilight zone! since light starts to dwindle their eyes are large to capture as MUCH as possible
Snailfish
HADAL ZONE
does red or blue have a longer wavelengths
red has the longest wavelength
when all colors are reflected, white light is formed
TRUE
what was Abril's and Deren's favorite deep sea animal
DUMBO OCTOPUS
How do tube worms convert minerals from hydrothermal vents into food?
BONUS - what are the specific reactants?
Chemosynthesis
Hydrogen Sulfide, Oxygen
twilight/mesopelagic zone
which type of luminescence causes glo in the dark stickers to glow?
a- fluorescence
b- phosphorescence
c- chemiluminescence
phosphorescence - Phosphorescent materials absorb energy from radiation, like light, and slowly re-emit it.
the headless chicken fish is in the twilight zone
FALSE - it is in the midnight zone
how do nudibranchs breathe?
exposed gill appendages
