Marine
Habitats
Kelp Forest
•
habitat found in
cold water right
offshore, sea
otters anchor
themselves in this
brown algae and
eat the sea
urchins that could
devastate this
habitat if
unchecked
coral reef
•
formation and area formed
by calcium carbonate
excretions, in the photic
zone and tropical latitudes,
provides a home for 25
percent of marine fish
species (lots of
biodiversity), many
organisms here, including
sponges, sharks, parrotfish,
eels, and even sea turtles
•
sandy beach
habitat along coastlines formed from sand
deposits, harsh place to live because of the
shifting tides, animals like ghost crabs and
beach hoppers live here, most of food is
organic debris (dead fish, loose seaweed)
that washes ashore
rocky shore
•
habitat subjected to the battering of
waves and periodic exposure to air, has
limpets, sea stars, mussels, and sea
urchins, along with seaweed/algae,
divided into definite zones based on tide
changes
mangrove swamp
•
has a dense canopy, along tropical
coastlines, protects coastlines against
erosion and storms, can find snails,
raccoons, pelicans, and even crocodiles
here
salt marsh
•
area where cord grass is abundant,
detritus is plentiful, and oysters, crabs,
and small fish thrive in these "nurseries",
GA has one of the most productive ones
in the world
hydrothermal vent
• a deep sea oasis of life,
formed around mid-ocean
ridges where cold water
seeps into the rocks and is
heated to 300-400 degrees C,
bacteria make food through
chemosynthesis, feeding
tubeworms, mussels, crabs,
shrimp, etc.
tide pool
•
where water collects in a small
depression, many animals here can
burrow down in the sand to camouflage
themselves and to prevent drying out,
like the rock crab
mud flat
•
habitat with a flat expanse of mud
deposited by slow moving water, bacteria
live in the mud decaying matter, many
clams, crabs, and snails live here
oceanic—photic zone
• open ocean area where light
penetrates and photosynthesis can
occur, lots of plankton, as well as
many fish, squid, whales, and jellies
oceanic—midwater realm,
twilight zone
•
zone between photic and aphotic, where
little light penetration occurs, many
animals tend to be black or red in color
and have large, sensitive eyes, comb
jellies and others migrate to the photic
zone at night to feed
oceanic—aphotic zone, deep sea
bottom
•
word meaning no light, this area includes
most of the ocean where food falls from
above and the organisms are quite
strange, growing slowly because of the
extreme pressure
•
subtidal
area from the low tide level to the
edge of the continental shelf always
submerged underwater, animals
found here can include sand dollars,
brittle stars, angel sharks, worms,
and stingrays
