What is seaweed? 3 types of seaweed you might not know.

Seaweed is sea vegetable. It grows in the coastal seas in shallow water with lots of sunlight. Most root to the ocean floor or to rocks.  Seaweeds are organized into three (3) groups by color: Red, Green, and Brown (not yellow!)

Seaweeds are not plants. They are algae, which means they don’t have seeds and flowers but instead have spores! Seaweeds not only provide a home for many aquatic species, but also are a source of food for them. Where do you think fish get their Omegas from?

1. Red seaweeds

The red color of red seaweeds come from the fact that they photosynthesize in dim light. The less light they receive, the darker the color. There are more than 7,000 species of red algae seaweeds. The red seaweeds are usually smaller than the brown seaweeds.  Sea moss or Irish moss is a type of red seaweeds.
