Transcript of Marine Life
Biotic and Abiotic Factors
Marine Biome Map
Examples of Predation:
A Great White shark and a Seal.
Dolphins and mackerel.
The Marine biome is the largest in the world. It covers over 70% of Earth. Consists of all five oceans:
Pacific 0.0000°S, 160.0°W
Atlantic 0.0000°S, 30.0°W
Arctic 90.0°N, 0.0000°W
Southern 20.0°S, 80.0°E
Indian 70.0°S, 150.0°W
Taylor Stoyko, Abby Miller, Chloe Moncayo
The average precipitation in the marine biome averages well over 100 inches per year because the biome is so large.
Since the Marine biome is the largest biome in the world the temperature varies from -40°F to over 100°F.
Adapt to high salinity of water
Adapt to different temperatures
Adapt to salt water by sorting salt out of the water so they can take in/store freshwater.
Affects of Abiotic Factors:
Some animals rely on currents for transportation
Thicker blubber to keep animals warm in colder temperatures
Examples of smaller Predation:
Clownfish prefer to eat the leftovers of usually copepods, isopods, or zooplankton.
Starfish eat mussels and oysters
Both organisms benefit
Clown Fish and Sea Anemone
The Clown Fish eats invertebrates that can be harmful to the anemone. The anemone provides shelter and protection to the clown fish.
One organism benefits and the other is not affected.
Sea Barnacles and Whales
Made by: Abby Miller
Sea Barnacles attach to some whales for protection and to receive nutrients. The whale is ultimately unaffected by this.
Christmas Tree Worm
Bearded Fire Worm
Over fishing, pollution, and introduced species have affected sea life negatively. Humans depend on fish as a source of food. Due to over fishing many fish stocks have decreased. All marine pollution has potential to damage habitat. The sea has been used as an international dumping ground for waste. Humans have had a negative impact on the marine biome.
Animals of the Marine
The walrus is a large flippered marine mammal mostly found in the Arctic Circle. They use their large tusks to pull their large bodies out of the water. The average weight of a walrus is up to 1.5 tons. They live up to 40 years, and are an endangered species.
Walruses eat a variety of things. From clams, worms, snails,shrimp, and slow moving fish.
There are 32 species of Dolphins. Dolphins live in mostly all the oceans. They are mammals and are a very intelligent species. They can be trained by humans, and even in some cases can learn to communicate with humans. Dolphins tend to live in groups that can range from 2 to 40 dolphins. Dolphins eat all sorts of things. It all depends on what ocean they come from.
