The Goldtipped Torch Coral, Torch Coral, scientifically known as Euphyllia glabrescens, is a captivating and popular coral species renowned for its unique morphology and vibrant colors.
Description & Characteristics
Euphyllia glabrescens is characterized by its distinctive branching structure, resembling a torch, hence its common name. Each branch of the coral colony can grow to a considerable size, with the overall colony reaching a maximum diameter of approximately 12 inches. The coral polyps, which are the individual living units, have long, slender tentacles that extend outwards from the central mouth. These tentacles are often tipped with vibrant, contrasting colors, giving the coral its distinctive “goldtipped” appearance. The polyp itself is typically a creamy white, with the tentacles boasting a palette of colors that range from deep red and orange to bright yellow and green.
Habitat and Occurrence
The Goldtipped Torch Coral, Euphyllia glabrescens, is a widespread species found in tropical and subtropical waters across the Indo-Pacific region. They typically inhabit shallow, protected reefs, residing in the subtidal, sublittoral, infralittoral, and deep zones of the oceans. This means they are prevalent from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. They are a common sight within the neritic marine zone, characterized by its relatively shallow depth and proximity to the coastline.
Taxonomy
The species Euphyllia glabrescens belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Euphylliidae. This classification highlights its close relationship with other stony corals, reflecting shared characteristics like their hard, calcium carbonate skeleton and their ability to form extensive colonies.
Feeding
Like many other corals, Euphyllia glabrescens relies on a combination of feeding strategies. It is a heterotrophic organism, meaning it obtains nutrients from external sources. Its primary source of nutrition comes from the symbiotic relationship with zooxanthellae, single-celled algae that reside within its tissues. These algae photosynthesize and provide the coral with organic compounds, contributing significantly to its growth and energy needs. However, Euphyllia glabrescens is also a carnivore, actively capturing small invertebrates and plankton using its tentacles. Its diet can also include dissolved inorganic substances like NaCL, CA, Mag, K, I.P, as well as dissolved organic substances. Additionally, it can be fed frozen food, particularly large varieties, phytoplankton, and zooplankton.
