The Intriguing Difference Between Seaweed and Kelp

For Plants

February 28, 2024

When it comes to marine life, the terms “seaweed” and “kelp” are often used interchangeably. However, there are distinct differences between the two that make each unique. Let’s dive in and explore these differences in detail.

Quick Answer:

Kelp refers to a specific kind of large, brown seaweed, while seaweed is a more general term that includes many different kinds of marine algae, including kelp.

 

What is Seaweed?

Seaweed is a general term used to describe many different species of marine plants and algae that grow in the ocean. This includes microscopic organisms like phytoplankton, as well as larger, more recognizable plants like kelp and nori.

The scientific term for seaweed is “algae.” Algae is a diverse group of aquatic organisms that have the ability to conduct photosynthesis. They range from small, single-celled forms to complex multicellular forms, like seaweeds. The term “seaweed” is often used to refer to larger, more visible types of algae, such as kelp and nori, which are integral to both marine ecosystems and human diets.

Seaweeds play a crucial role in marine ecosystems. They provide food and shelter for many species and produce a significant percentage of the world’s oxygen through photosynthesis. Seaweeds are also an essential part of human diets in many cultures, especially in East Asia, where they are often used in soups, salads, and sushi.

 

What is Kelp?

Kelp is a specific type of seaweed. It is a large brown algae that belongs to the order Laminariales. Kelp grows in “underwater forests” in shallow oceans and is known for its high growth rate—the fastest species can grow up to half a meter a day!

Kelp, a specific type of seaweed, is predominantly found in cooler, nutrient-rich waters. These conditions are ideal for its growth and survival. Unlike some other types of seaweeds that can inhabit various environments, kelp is specifically adapted to these cooler waters. Kelp forms large, dense colonies that are commonly referred to as ‘kelp forests.’ These kelp forests, which can be vast and dense, provide a rich habitat and serve as a source of food for a myriad of marine species. The existence of these underwater forests demonstrates the adaptability and resilience of kelp, highlighting its crucial role in maintaining marine biodiversity.

Kelp forests are incredibly productive ecosystems that provide homes and food for numerous marine species.

Many marine species rely on kelp for survival. Kelp forests provide a rich habitat and serve as a source of food for a myriad of marine species. This includes, but is not limited to, various types of fish, crustaceans, sea urchins, and sea otters.

They can also help protect coastlines from wave action. Kelp is used in various products, including food, fertilizers, and even in the production of biofuels.

 

So, What’s the Difference?

Kelp is seaweed, but not all seaweed is kelp. Kelp refers to a specific kind of large, brown seaweed, while seaweed is a more general term that includes many different kinds of marine algae, including kelp.

Seaweed can differ in size, color, and habitat. It can be microscopic or up to 60 meters in length. It can be green, red, or brown. It can live in either cold or warm waters, and it can grow along rocky shorelines or float freely in the open sea.

Kelp, on the other hand, is always large and brown and grows in cooler, nutrient-rich waters in large colonies known as kelp forests.

 

 

While kelp and seaweed are closely related and share many similarities, they are not the same. The next time you see these terms used, you’ll understand the fascinating differences that make each unique in its own right!
