Biome Project- Marine

By: Megan Toper

Marine location

The Marine takes up 70% of our earth. The oceans are Pacific, Atlantic, Indian, Artic, and Southern. They are also found on some smaller gulfs and bays.

Marine climate

The temperature normally varies. Since it is the largest biome in the world the temperature can range from -40 degrees to over 100 degrees. There is no annual precipitation because we are already underwater.

Six animals in my biome

Orca/ Killer Whale

Killer whales adaptations are that they can swim very fast to catch its prey and it has its blubber for warmth. A fun fact is that once a baby is born it learns to swim within 30 minutes of its arrival.

Sea Star

A Sea Stars adaptations are that they have a strong sense of smell. They can detect chemicals coming their way. This keeps them away from harm. A fun fact is that they have a feature called autonomy which means that if they lose an arm it will just grow back.


A dolphin is not a fish, so it has to breath air. When the dolphin breathes air it can last them up to 10 minutes underwater. A fun fact about dolphins is that they swim at the speed of 5 to 11kph.

Great White Shark

The Great White Shark has big jaws and teeth. These features help it catch its prey and hunt for food. An interesting fact about a Great White Shark is that they can almost live anywhere. They have even been spot in Hawaii.

Sea Turtle

Sea Turtles are very strong swimmers. They have forelimbs which are like long paddles flippers for swimming. An interesting fact about them is that they can stay submerged under water for 35 to 45 minutes.

Beluga Whale

The Beluga Whale are adapted to be maneuverable not fast. A Beluga whales circulatory system is modified in a way so that they can maintain body heat. An interesting fact is that they are also known as sea canaries.

Four plants that live in The Marine


Algae relies on water to grow, so if you put it in the desert if wouldn't even be able to come to life. Humans rely on algae a whole lot because they produce 70% of the oxygen we breathe.

Sea Grass

Sea grass is only able to survive in a marine biome, in the water. If you put it in the tundra the snow would overpower it and it would die. An interesting fact about sea grass is that they can produce over 10 tons of grass each year.


Kelp is very important to the marine biome. Sea otters is its main predator. If you put kelp in the freshwater environment it would probably survive, but the sea otters wouldn't have anything to eat and would die. An interesting fact about them is that they can be used in medicines.

Red Algae

Red Algae is very important to the Marine because they form reefs for sea animals to live in. If you put it in the taiga there wouldn't be enough moisture to sustain the plant. An interesting fact is that they have 10,000 species.

Interesting Facts

1. It is home to largest animal in the world.

2. It takes up 140 million square miles.

3. The ocean contains more than 20 million tons of gold.

4. Even though we are in the ocean, there are mountains there.
