What are the characteristics of seaweed?

The Hawaiian way to say seaweed is limu. It is one of the sources we use for food. There are about 420 species that grow in Hawaii. 13 of the 420 species can only be found here in Hawaii. Seaweed can be found in different colors (red, green or brown), shapes and sizes. It is mostly found near the shore, in the intertidal zone. Seaweed is gathered at beaches, near shore waters, and can also be found in vast underwater forests or floating on the water's surface. Seaweed can be very tiny or stretch to 300 ft or 100 m. That's like from the ocean floor to the surface!Seaweed is like an underwater weed because it grows freely and often times plentiful, but it is used for many things and is not a weed at all. Seaweed has many plant-like features, but they are not true vascular plants, they are marine algae. Algae is part of the Kingdom Protista, they are neither plants nor animals.

also,seaweed can live up to 500 meters deep in the sea.Seaweeds cousin

protists,can cause harmful things to the sea killing fish,even sometimes

humans.This is called a red tide.This can also be caused by blue-green

algae.
