Tubastraea

Tubastraea is a genus of colonial stony corals in the family Dendrophylliidae. These corals are often called “sun corals” or “orange cup corals” due to their distinctive appearance and color. They are found in tropical and subtropical waters throughout the world, with some species being considered invasive in certain regions.

Characteristics

Tubastraea corals are characterized by their distinctive cup-shaped corallites, which are typically orange, yellow, or brown in color. Each polyp has a single, prominent oral disc with numerous tentacles. Unlike many other stony corals, Tubastraea species are able to reproduce both sexually and asexually, and they can grow rapidly under favorable conditions.

Environments

Tubastraea corals are typically found in shallow, sun-lit waters, often in association with other invertebrates such as sponges and sea anemones. Some species, such as Tubastraea coccinea, are also known to inhabit deeper waters, up to 200 meters. They can be found in a variety of habitats, including reefs, rocky shores, and even submerged structures like piers and shipwrecks.

Invasive Species

Some Tubastraea species, such as Tubastraea coccinea, have been identified as invasive species in certain regions. These corals can outcompete native species for space and resources, leading to a decline in biodiversity. Their rapid growth and ability to reproduce both sexually and asexually contribute to their invasive potential.
