What Is Kelp?

Kelp is a type of large seaweed that belongs to the Laminariales group. It grows in underwater forests in shallow, nutrient-rich saltwater, usually in cooler coastal areas. From the physical structure of kelp forests to their role as a habitat for marine organisms, kelp has big, leaf-like parts called blades and long, stem-like parts called stipes that anchor it to the ocean floor.

  • There are around 30 different kinds of kelp with hundreds of species worldwide. Some common types include giant, bull, sugar, and also bladder kelp, which accounts for 21 percent of Japanese meals and is suggested as a reason for their above-average life span.
  • Giant kelp, or Macrocystis pyrifera, is one of the fastest-growing plants on Earth, stretching up to 18 inches a day in the right conditions.
  • Kelp forests are incredibly important to ocean life. They provide food and shelter for many fish, sea creatures, and also marine mammals.
  • Because of their rich diversity and crucial role in the ecosystem, these underwater forests are often called the “rainforests of the sea.”
