Introduction to Biology of Coral Reefs Coral reefs are the largest structures ever built by living organisms Inhabited by greater diversity of types of organisms than any other ecosystem 0 Every organisms I linked to many others in a complex web of interactions Coral reefs are extremely vulnerable to destruction by human activities Reefs protect coastlines from damage by storm waves and shelter sh and other sea foods 0 Other coral reef resources include aquarium animals building and decorative materials pharmaceutical and diving tourism Where are the coral reefs Corals that build reefs require 0 Warm waterbetween 25 degrees N and 25 degrees S latitude o Sunlight a shallow bottom and clear water 0 Normal Salinity away from rivers 35 0 Moderate water movement F Reef building can only inhabit areas with Coral Reefs are part Animal Part Plant and Part Rock Rock as corals grow they deposit skeletons of A39 sunl39ght B Normal seawater caICIum carbonate salinity Live tissue is a thin layer on the surface C Animal corals are related to sea anemones and D jelly sh all in the group of animals called cnidarians o All cnidarians have a saclike design a mouth nged Clear Water Warm water Corals reproduce sexuallv producing eggs and sperm which unite to form an embryo Some species release eggs and sperm into the water where fertilization occurs and others release only sperm and fertilization occurs inside the female colonies Spawning when eggs and sperm are spread out in the water all at once by male and female corals Planula larvae that escape predators and settle ina good spot grow into small coral colonies What are 2 important reasons why is makes sense to care about te health of coral reefs What are 2 important ways in which humans bene t from healthy coral reefs Describe 2 ways in which the life cycle of a reefbuilding coral differs from a human life Carl Linnaeus created the biological classi cation scheme of grouping all living organisms Every Species had a twopart scienti c name consisting of the genes and species humans are Homo Sapens bottlenose dolphins are Turiops truncates The most fundamental division is o Prokaryotes are very small and simgle cells gt Prokaryetes were the rst Including bacterIa and bluegreen algae organisms to live on earth The Eukaryotes are divided into 4 kingdoms Protista a single celled Fungi constructed of lamentous hyphae o Plantae manufacture their own food using All except fungi are energy from sunlight well represented on o Animalia have to eat food coral reefs Kingdom All protists are 0 single celled gt 0 but vey complex and much larger than prokaryotes cells 0 Many protists cause problems Red tides which make some seafoods toxic are caused by a protists Kingdom 0 Plants make their own food using energy from sunlight to transform water carbon dioxide and nutrients into living tissue Algae seaweeds have no roots and soak up nutrients and water trough their surfaces in coral tissue are protists o Flowering Plants acquire nutrients and water through their roots their reproductive organs are in owers Kingdom 0 Animals have to eat food Familiar birds sh and mammals represent only a tiny fraction of diversity of animal life forms and styles Green algae Red algae Brown algae Phylum Sponges pump water through their canals and lter out tiny food particles Sponges are Simple and homogenous Flexible in form Able to regenerate Phylum corals sea anemones and jelly sh All cnidarians have 0 A saclike gut A mouth ringed by tentacles Nematocysts Phylum segmented worms 0 Earthworms are annelid worms 0 All annelid worms are Bilaterally symmetrical with a head end and a tail end Divided into segments the rst few can be modi ed into many types of feeding structures Phylum calms snails sea slugs squids and octopuses All mollusks Have a muscular foot Phylum Crabs shrimps lobsters All arthropods have Jointed appendages exoskeleton that they must shed in order to grow 0 Bilateral symmetry Phylum star sh sea urchins sea cucumbers brittle stars sea lilies crinoids All echinoderms have Pentaradial symmetry The key distinguishing characteristic between members of the kingdom plantae and embers of the kingdom 39 TUbe feet I I I animalia is Calcareous bits embedded in their Skin A Plants are unable t live in seawater B All animals can move D Only animals reproduce is someone showed you a mystery animal and asked you to please tell them the phylum to which it belong which 2 characteristics would allow you to continuously declare the mystery animal to be 1 An echinoderm tube feet and Pentaradial symmetry 2 An arthropod jointed appendages exoskeleton that they must shed in order to grow and Bilateral Symmetry Two phyla characteristics by radial Phylum Chordata birds reptiles sea Symmetry are squirts sh and mammals A Arthropods sponges B Cnidarians annelids C Annelid arthropods E Arthropods echinoderms
