---------------------------
HABITAT
This red algae lives in the tropical oceans. It is one of the amazing organisms that make up the coral reefs in the seas. They tend to live in the deeper waters because of its pigment that absorbs blue light.

PREDATORS
Because of it's habitat in the seas, the Gibsmithia hawaiiensis is constantly preyed by many other sea creatures. Some predators can be fish and crabs.

ITS PREY
The Gibsmithia hawaiiensis don't need to devour anything to survive; it eats NOTHING. Algae has the ability to make its own food with chlorophyll. Chlorophyll is a pigment that takes in sunlight to generate energy for food production. Then carbon dioxide is taken in from the water to make glucose. Glucose, a type of sugar, is their source of food.

ANATOMY
As multicellular organisms, the Gibsmithia hawaiiensis can be seen with the naked eye. They possess three pigments: phycoerythrin, phycocyanin and allophycocyanine. The pigment phycoerrythrin gives the organism a red color. This is also the pigment that reflects red light and absorbs blue light. This algae appears in a funny form that makes it stand out from all the other algae types. It has many thick loose branches branching out from a central root. Its branches have a round, curvy shape. In addition, these algae can vary from 3-12 cm in size.
EXTRA
The oldest red algae fossil found was also the most ancient eukaryote fossil discovered.

Also, red algae is a great daily use in our world. They carry ingredients such as carrageenan and agar in them, which are often used as gelling agents for food, paint, and cosmetics. If sheets of algae are toasted, they can also be used to wrap sushi.
