Animal Life in the Ocean By Daniel Gonzalez & Gio Aranda
The Zones of Survival • Epipelagic Zone -very Shallow -abundant with fish big or small • Mesopelagic Zone -Also known as twilight zone -Little light penetrates -Goes down to 3,300 • Bathypelagic Zone -Also known as Midnight zone -At depths of 20,000 feet • Abyssopeligic Zone -At depths of 13,123 to 19,685 feet
Epipelagic Zone • This is ideal place for about 90 percent of all ocean life. • Sharks, mackerels, tuna, seals, jellyfish, sea lions, sea turtles, sting rays, and much more live in this area. • Some species have developed a camouflage called counter shading • Counter shading is when a specie’s skin is dark on the top of their bodies, and light on the bottom. • The shark is a example.
Creatures of the Twilight • This Zone is formally known as Mesopelagic Zone • The twilight zone has some animals including octopus, squid, and hatchet fish • The animals living in this zone must survive -- cold temperatures -- increased water pressure -- dark water • Some fish has big eyes to help them see but there those that make there own light called bioluminescence. • A example of bioluminescence is the Hatcher fish
The creatures of Midnight • This zone is formally called the bathypelagic zone. • This Zone has a very intense water pressure • The fishes seen in this zone are vampire squid, giant squid, amphipod, slime stars, snake dragon fish, anglerfish, oarfish, gulper eel. • Only one percent of all ocean species live in this zone
Creatures of The Abyss • This zone is formally Abyssopelagic Zone. • The creatures in this zone are Black swallower, tripod fish, deep-sea anglerfish, and the giant squid • Many abyssal creatures have underslung jaws to sift through the sand to catch food • Under slung mean to have a part projecting beyond the upper body.
