Focus On….
Marine (ocean or sea) - including
littoral or intertidal zones
euphotic (sunlit) zone
Coral reef (warm shallow salt-water environments
based on coral formations)
Biomes:
• estuarine biomes (where rivers meet oceans)
• pelagic biomes (open seas near the surface)
• disphotic (twilight) zone
• midnight (aphotic) zone
• benthic biomes (bottom)
• sea trenches
• sea Caves
Creatures of the Sea
Organisms to be covered: Blue Whale, Shark, Clown fish, sea turtles,
coral reefs, sea turtle, zoo plankton, etc…

Clown Fish
Habitat
• Clownfish belong to a group of small, brightly colored
fish called damselfish. These inshore reef dwellers have
developed a curious and potentially deadly relationship
with the sea anemone.
Reproduction
• Clownfish lay their eggs in batches on the clear coral or
rock adjacent to the anemone, or at the base of the
male guards the eggs until they hatch 4-5 days later. In
some species of clownfish, the male cares for the young
until they reach sexual maturity, at which time they
leave to find their own host anemone.
RETURN
Sea Turtles
• Sea turtles are found in warm and temperate seas
throughout the world.
Habitat
• Adults of most species are found in shallow, coastal
waters, bays, lagoons, and estuaries. Some also venture
into the open sea. Juveniles of some species may be
found in bays and estuaries, as well as at sea.
• Like other turtles, sea turtles lay eggs. They must come
ashore to do so.
RETURN
The Marine Food Chain
Phytoplankton is the first level of our food chain,
followed by the zooplankton, which feeds on the
phytoplankton. The zooplankton are then eaten
by krill, fish and other crustaceans, which all go
on to be eaten by big fish, penguins, seals,
walruses and whales. The food chain continues
when these are eaten by mammals like polar
bears.
Return
Marine Biomes
The marine regions are divided between coral reefs,
estuaries, and oceans. Oceans represent the largest
and most diverse of the ecosystems; salt water
evaporates and turns to rain which falls on the land
regions, while most of the oxygen in our atmosphere is
generated by algae. Algae is also responsible for the
absorption of large amounts of carbon dioxide from our
atmosphere. Return or For even more information click
