Algae are some of the most overlooked but important organisms on the planet. They are simple celled organisms that often use photosynthesis to gather nutrients. They can be found in fresh water, but there are also many different types of marine algae that fill the world’s oceans. Most of these algae are complex organisms more commonly referred to as seaweed.

Giant Kelp

One of the most amazing types of marine algae on earth is the giant kelp. Giant kelp is a type of green-brown seaweed that is common in shallow waters in the Pacific Ocean, specifically along North, Central and South America’s Western coast. Giant kelp is almost the fastest growing organism on the planet. It grows to about 160 feet long in total and, as it is maturing, can grow at a rate of about two feet per day.

Giant kelp is important for many reasons. It forms large habitats and shelters for a wide variety of marine life. In addition, many people can also benefit from the raising and harvesting of giant kelp. Products produced from this kelp include alginate, iodine and potassium. Giant kelp can also be used as a food source for farmed marine life.

Codium Fragile

Another fascinating type of seaweed found in the ocean is Codium fragile, more commonly known as green fleece seaweed or dead man’s fingers. Codium fragile is, as its nicknames imply, a fluffy, spindly bright green species that grows in small clumps. This seaweed generally clings to rocks, and can be about a foot long.

Codium fragile is originally thought to have come from Asia. However, this species has gradually drifted around the world, and has become an invasive species in many areas. This alga can now be found in Europe, Norway, Denmark and Asia, as well as along the eastern coast of the United States.

Gracilaria

Gracilaria is a type of bright red algae. This seaweed, which has several different species, is found around the world. It grows in thin, spindly branches, and looks a bit like a clump of wiry red wool. Gracilaria is not only lovely to look at but is an important species because it is heavily used in some Asian cuisines. This seaweed is popular with Hawaiian, Filipino, and Japanese chefs. The agar the seaweed produces is often used to make jellies, sweets, and sticky, savory dishes. In addition, this agar is sometimes used in scientific experiments.
