OVER THE YEARS In 1872 the British ship Challenger, set sail for three- and- a- half years. The crew threw nets down into the ocean and discoveredfour thousand new speciesWilliam Beebe and Otis Barton made a bathysphere or as we know it today, a submarine.
In the past, submarines were made out of quartz and steel and they still are todayBathysphere
OVER THE YEARS (CONT)The ocean covers 70% of the EarthScientists have only discovered 5% of the ocean out of 70%You might think thats not a lot, but there are a lot of places in the ocean that are too dangerous to explore our to deep down to travel toScientists have found hydrothermal vents that use the chemicals in the hot water to make food for the animals that cant find anyHydrothermal vents
ANTARCTICAIn the 2000s scientists discovered Yeti Crabs and Albino Octopuses Yeti Crabs have hairy chests and hairy armsScientists described the moving crabs as bees because they are always busyThey also have bacteria growing on their arms Yeti Crab
The chart above is a picture of the different layers of the ocean. Many different animals lived in these zones. The next few slides will describe the different zones and the animals that live there.Ocean Zones
The Epipelagic Zone- Algae The Epipelagic Zone is where most of the plants and animals of the ocean liveIt is nicknamed the Sunlight Zone because it is where most visible light existsAlgae is a plant that is found in the Epipelagic ZoneIt provides oxygen for other marine animalsAlgae grows by the process of photosynthesisPhotosynthesis- a process used by plants and other organisms to covert light energy, normally from the sun, into chemical energy that can be later released to fuel the organisms activities Ocean Algae
Mesopelagic Zone- Comb JelliesIn the Mesopelagic Zone, fish use bioluminescence to see in the dark watersBioluminescence- is the production of light by a living organismOne animal that lives in the Mesopelagic Zone is the Comb JellyIt is not related to the jellyfish at allThe Comb Jellies have lived in the ocean for about 5 million yearsIt has long trailing tentacles and will almost eat anything it runs intoComb Jelly
Abyssal Zone- Giant SquidSunlight doesnt reach the Abyssal ZoneThe animals in this zone usually are invertebrates Invertebrates- animals without a backbone The Giant Squid lives in this layer of the oceanIt moves by jet propulsion which consists of collecting the ocean water and shooting it out Giant Squid
Hadal Zone- Sea Cucumber & Sea SpiderNicknamed the Trench Zone because the deepest trenches are in this zoneIt is dark and cold Animals in this zone have adapted to the darkness by reducing their use of eyesightThe Sea Cucumber eats floating food like algae They break down their food into tiny pieces which then becomes food for bacteriaThe Sea Spider is related to horseshoe crabs, scorpions, and mitesThey eat jelly fish and other soft body animals by ripping them to bits
