3 May 2013 Classification General Info Habitat Biome food- sea urchins, seaweed, and mostly jellyfish
shelter- almost all oceans of the world in the open water or beaches where they nest & where they're born. (Some live on seaweed rafts as hatchlings in the ocean)
water- gets water from the ocean, metabolizes it to purify it.
body temperature- they have no specific body temperature, but they can survive in colder waters due to adaptations that allows them to be 18* C warmer than surrounding water Leatherback Sea Turtle Classification Kingdom: Animalia Phylum: Cordata Class: Reptilia Scientific Name: Dermochelys Coriacea (genus- Dermochelys) adult size:
1.5-2.4 km (6-8 ft) adult weight:
350-900 kg (800-2,000 lbs) adult color:
carapace (upper part of shell)is black with small white dots
plastron (lower part of shell) is white with large black blotches
pinkish belly hatchling color:
grey/black with white bordering that will eventually turn into white spots. The leatherback does not change colors during seasons Marine biome
Mostly in tropic, coastal, and temperate waters
Specifically in the Atlantic, Pacific, Indian, and Mediterranean oceans
Animals in this biome include...
- sharks
- squid
- jellyfish
- sea urchin
- crustaceans
- some coral
Plants found in this biome include...
- seaweed
- kelp
- algae
- seagrass
- red algae Adaptations Getting water:
The turtles use sea water and filter it through their metabolism. They get rid of unwanted salt through salt glands that form tears to leave the body. Body temperature:
Its dark, thick oily skin and thick layer of fat help retain a good body temperature. It also has a type of circulatory system where the arteries and veins lay close together to help the blood in both get warmer. getting and eating food:
The throat and mouth of the turtle are lined with spikes to help trap their jellyfish prey, and they have sharp cusps as well as a pointy-lined jaw. Protection:
The hatchlings are very vulnerable to predators but as the turtle gets older, their large size helps protect them and helps them become predators. Thanks for watching!! Interesting Facts 1. Deepest-diving of almost all vertebrates
2. Leatherbacks make 3,700 mile migrations each way.
3. Biggest leatherback ever found was 2,020 lb. and 8.5 ft. Gestation reach maturity at 15-21 years old
lay about 80-100 eggs every 2-3 years
the offspring are called hatchlings
must learn to survive on their own after they hatch Habits and Behaviors can dive up to 1,000 m. below the surface
swims very fast with slick shell and large flippers
able to make very long migrations
sleep for several hrs. at a time underwater Bibliography Ripple, Jeff. Sea Turtles. Stillwater: World Life Library, 1996. Print.
