Course DescriptionMarine biology is the science of saltwater and everything that lives, moves, and filters through it. The word "marine" in this sense refers specifically to saltwater that you find in oceans, not freshwater, which is found in lakes.
When you look at a globe, you can see that nearly three quarters of the Earth's surface is covered with water. Scientists believe life on Earth got its start in the ocean, and gradually adapted to life on land. Some land-based organisms eventually returned to the water, like dolphins and whales. Tiny ocean plants, called phytoplankton, produce most of the oxygen in the air we breathe. When producing oxygen, these plants soak up carbon dioxide, removing this gas from the air.
The ocean is always in motion: currents move water around the globe. Water evaporates and rises into the atmosphere where it will eventually fall as rain and snow. Cold water sinks in the ocean, warm water rises, and this constant movement distributes heat and nutrients around the globe.
In this course, you will learn about life in the ocean depths, at the Polar extremes, in coral reefs, estuaries, and in the open sea. You will learn about plants large and small, marine birds, reptiles, invertebrates and fish. You will learn how all these organisms connect with each other in the marine biome, and what threats are facing these ecosystems.

Lesson 1: IntroductionMarine biology is the science of saltwater and everything that lives, moves, and filters through it.
Lesson 2: Geology and the OceanThe area where old crust is sinking under another slab of crust is called a subduction zone. Subduction zones create such deep trenches that they are all below sea level.
Lesson 3: Currents and TidesThe term current refers to the motion of water. On land, the motion of water is usually driven by gravity: rain falls from clouds and then runs downhill toward lakes and to the ocean.
Lesson 4: What's in a Name?A species is a group of organisms that are able to successfully reproduce with one another.
Lesson 5: InvertebratesThe jellyfish, for example, contracts its umbrella shaped body to propel itself through water. Other invertebrates use water pressure, shell, or cups to support themselves.
Lesson 6: VertebratesThere are seven main classes and superclasses of vertebrates that include fish, reptiles, amphibians, birds and mammals.
Lesson 7: Marine FishThe study of fish is called ichthyology, and ichthyologists have grouped all fish into three main categories: jawless, cartilaginous, and bony.
Lesson 8: Marine MammalsMammals, whether they live on the land or in the sea, are all vertebrates (meaning they have a backbone and a brain).
Lesson 9: Marine EcosystemsA biome is a large geographical area that contains several different ecosystems. All the plants, animals and other organisms that live in a biome are adapted to that environment.
Lesson 10: Life at the ShoreThe intertidal zone (also called the foreshore, seashore and the littoral zone) is the area that is exposed to air at low tide and underwater at high tide.
Lesson 11: EstuariesAn estuary is one type of intertidal zone, where a river meets the sea: freshwater meets saltwater in a bay, lagoon, sound, or slough.
Lesson 12: Coral Reef BiologyCoral reefs are usually found in the tropics, and although corals make up a big part of the reef, they are just one component of an enormous community.
Lesson 13: Coral Reef EcosystemsMany marine scientists think that most reefs start out as fringe reefs, and over time, the coral grows out and away from land. As it gets farther from land, the reef's diameter expands and a large lagoon forms.
Lesson 14: Life in the Polar OceansAlthough the two poles have a lot of similarities, like very cold weather and extreme living conditions, life in the two regions was shaped by a different series of circumstances.
Lesson 15: The Open SeaThe open ocean is the largest biome in the world by volume, but in terms of the quantity of life, the Pelagic resembles the most enormous desert ever known.
Lesson 16: Life in the Ocean's DepthThe Benthic Zonerefers to the sea floor, which extends from the tidal areas all the way down to the deepest trenches on the planet.
Lesson 17: Oceans in JeopardySome of the major threats facing the oceans include climate change, pollution, nutrient runoff, garbage dumping, overfishing, and ship strikes.
