  1. Tropical Oceans By: Katelin Rose McDonald

  2. Coral Reefs • Consists of several thousand organisms living together. • Warm and shallow water • Grow slowly (1 inch takes 100 years) • Covers 600,000m of the ocean • Home to 500,000 species • When coral dies it leaves a skeleton of calcium carbonate behind. The new coral attaches itself to the skeleton and starts again.

  3. Location • 23.5 S lat & 23.5 N lat • Great Barrier Reef: Australia • Hawaii, Red Sea, and other tropical oceans • Circle Earth in an equatorial band between Tropic of Cancer and Tropic of Capricorn • Central portions of Pacific and Atlantic oceans and most of Indian

  4. Climate • Temperatures exceed 68⁰F • Rainfall • Intense radiation over equator evaporates seawater and forms a mass of very warm, humid tropical air that rises and cools as it flows. Because cool air holds less moisture, the water vapor quickly condenses into clouds and falls as rain. • Warm, heavy, year round rains are typical.

  5. Climatogram

  6. Bethnic Zone • The ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers • Animals here live in close relationship with the substrate bottom. • Organisms here play an important role in the food chain and break down of organic matter • Provides an area for spawning, foraging, and refuge for various fish species, and benthic habitats function in nutrient cycling

  7. Plants • Algea (Seaweed) • Brown, green, and golden • Halimedaplant •  irregular oval segments of Halimeda appear as several small green coins glued from end-to-end, forming a chain •  Red Mangrove Propagule •  grows in the upper end of the intertidal waters of the tropical oceans of the world

  8. Animals • Clown Anemonefish • Amphiprionpercula • Green Turtle • Cheloniamydas • Jellyfish • ChrysaoraFuscescens

  9. Food Chain

  10. Adaptions • Most animals camouflage • Clownfish-poisonous mucus • Hammerhead-unique shape • Crustaceans-exoskeletons, segmented bodies, and claws to capture food • Sea cucumbers-poisonous, throws out organs to scare away predators

  11. Resources • Salt, magnesium, placer gold, tin, titanium, and diamonds • Limestone and gypsum • Various fish and food for consumption ~These mounds of sea salt were mined from deeply buried beds deposited when sea water evaporated in an ancient environment.

  12. Human Effect on Biome • 10% of coral reefs are completely destroyed • In Philippians 70% destroyed 5% in good condition • Indirect effect • Direct effect
