Ophidiaster guildingi is a species of starfish belonging to the family Ophidiasteridae. It is a common and widespread species found in the Indo-Pacific region.

Description & Characteristics

Ophidiaster guildingi is characterized by its distinctive five-pointed star shape and its relatively large size. Individuals can reach a maximum diameter of around 15 centimeters. The starfish’s body is typically covered in small, granular bumps. Its arms are relatively short and stout, tapering towards the tips. The color of Ophidiaster guildingi can vary depending on the individual and its environment. It is commonly found in shades of brown, red, orange, and yellow.

Habitat and Occurrence

Ophidiaster guildingi is a primarily benthic species, meaning it lives on the seafloor. It is commonly found in shallow coral reef environments, as well as in seagrass beds and sandy areas. Ophidiaster guildingi is distributed throughout the Indo-Pacific region, ranging from the Red Sea and East Africa to the Pacific Ocean. This species is commonly found in tropical and subtropical marine zones, typically inhabiting depths ranging from the intertidal zone to depths of around 50 meters. This wide distribution and preference for shallow, nearshore environments make Ophidiaster guildingi a prevalent presence in these aquatic ecosystems.

Taxonomy

Ophidiaster guildingi is classified within the phylum Echinodermata, which also includes sea urchins, sea cucumbers, and brittle stars. It belongs to the Class Asteroidea, which encompasses all starfish species. Ophidiaster guildingi is further classified within the Order Valvatida, a group of starfish characterized by their valvate pedicellariae (small, pincer-like structures on their bodies). The family Ophidiasteridae includes a number of other starfish species that share similar characteristics, such as their typically five-armed body plan and their granular texture.

Feeding

Ophidiaster guildingi is a carnivorous species, feeding primarily on a variety of invertebrates. Its diet consists mainly of sponges, algae, and other benthic organisms. It uses its tube feet to capture and manipulate its prey before consuming it. Ophidiaster guildingi plays an important role in the ecosystem as a predator and as a food source for other marine organisms.
