Transcript of "Ocean Life"

  1. 1. Ocean Habitats • Ocean animal habitats are divided into layers or zones according to the amount of sunlight each receives.
  2. 2. Zones The Sunlight Zone (Light Zone) • 0 feet – 600 feet Starfish • Receives the most light The Twilight Zone • 600 feet – 3,000 feet Squid • Receives very little light The Midnight Zone (Dark Zone) • 3,000 feet – 15,000 feet • Only light produced by bioluminescence Angler Fish

  4. 4. Coral Reefs • Corals are small, soft- bodied animals that live in shallow waters of the oceans (Light zone). • They develop a rock skeleton that forms a hard shelter for the tiny corals. • The rock makes up coral reefs.
  5. 5. Helpful Coral Reefs • Coral reefs protect the shoreline from tropical storms & makes safe harbors for ships. • Fish and lobsters thrive on the reefers provide food for people. • Many tiny fish hide in reefs. They can find food there and bigger fish also swim around reefs for their food.
  6. 6. Coral Reefs in Danger!! • More than 35 million acres of coral reef have been destroyed because of humans! Human Contact Touching Reefs, even slightly, can harm them. Boats and dropped anchors can cause severe damage. Frequent human contact kills the reefs over time. Fertilizer/Pollution Fertilizer runoff, pesticides and other chemicals can poison reefs. Cyanide Fishing Some fishermen stun fish by squirting cyanide, a very toxic poison. The poison does not kill, but disorients the fish in the coral where they hide. Cyanide kills coral polyps and the algae and other small organisms necessary for healthy reefs. Cyanide Coral Polyp fishing is common in the South Pacific and Southeast Asia.
