Focus On…. euphotic (sunlit) zone littoral or intertidal zones 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… To learn more about these organisms just click on the picture!

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.
