Document Summary

Symbiosis co occurrence of 2 different species interacting with each other in different ways; i. e. anemonie fish: mutualism host and symbiont both benefit, commensalism symbiont benefits, host gets no benefit but is not harmed; i. e. pilot fish living off shark, parasitism symbiont lives in or on host, feeds at host"s expense; i. e. nematode worms (cid:1) (cid:1) Each zone has its own evolved flora and fauna: algae, barnacles crustaceans; arthropods, gastropods intertidal lower middle and upper, as well as supratidal (cid:1) (cid:1) 11/23/2015 (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Three types of coral reefs (1) fringing reefs surround volcanoes (2) reef atolls: sand accumulates, some individual areas of coral growth, cross section through atoll, coral reef generates those moat looking shorelines that surround the island (3) barrier reefs surround sinking volcano, not fully only partial, australian corals can withstand exposure at surface, caribbean corals cannot this is an adaptation due to different tidal patterns.
