Maripelta (red algae) has a single blade that can grow to almost 5 inches in diameter and typically sits upon a two inch stem. It is deep red in color and is known to produce its blade seasonally. All types of red algae, collectively known as rhodophyta, contain two substances of economic importance that are widely used in food and pharmaceutical industries. These two compounds are agar and carrageenin which both help thicken everyday products such as toothpaste and ice cream.

Since blue light penetrates deeper than most other colors of the spectrum and red algae absorbs blue light for photosynthesis, it can grow deeper on average than most algae.
