Coralline algae
Corallinales
Coralline algae are special plants that live in the ocean. They help make coral reefs strong and colorful, providing homes for many sea creatures.
Habitat: Coastal areas
Appearance
The Coralline algae is primarily pink, red, or purple, forming hard, stony crusts or intricate branching structures. Unlike soft, leafy seaweeds, its unique calcified body makes it feel rough and rigid, resembling tiny underwater rocks or corals.

Interesting facts
Fossils show these ancient plants have been growing in oceans for over 500 million years!
Some make natural sunscreen to protect themselves from harsh sunlight!
Their tough, stony bodies are made of calcium carbonate, just like clam shells!
These ocean architects help build huge coral reefs by cementing them together!
Special abilities
Ability
Stony Shield
Coralline algae can harden its body with calcium carbonate, creating a tough, protective shield against grazers and strong currents.
Ability
Light Seeker
Coralline algae has special pigments that help it capture sunlight in deeper, dimmer waters, allowing it to photosynthesize.
Ability
Coral Caller
Coralline algae releases chemical signals that attract baby coral polyps, guiding them to settle and helping new coral reefs grow.

Traits
Nonvascular
This trait characterizes plants lacking specialized vascular tissues (xylem and phloem) for transporting water and nutrients.
Salt Tolerant
Salt tolerant plants can withstand and grow in conditions with elevated salinity levels in the soil or water.
Colorful
Colorful describes organisms or objects displaying a wide range of bright and distinct colors.
Ancient Lineage
This trait signifies organisms belonging to a very old evolutionary group with ancestors dating back millions of years.
Decomposer
Describes organisms that break down dead organic material, recycling nutrients back into the ecosystem.
Coastal
Coastal habitats are dynamic environments located along the interface between land and sea, influenced by tides, waves, and saltwater.
Keystone Species
Describes a species whose presence and role have a disproportionately large effect on its environment.
Marine
Marine habitats encompass all saltwater environments of the Earth's oceans, supporting an immense diversity of aquatic life.
