Ophidiasteridae

Characteristics

Ophidiasteridae species are characterized by several distinctive features:

• Slender, elongated arms: They typically have five arms, but some species can have up to 10. These arms are much longer than their central disc, and their tips are often pointed.
• Flexible arms: The arms are highly flexible, allowing them to move through narrow spaces and navigate complex coral reefs.
• Spines: Their bodies are covered in spines, which are typically small and granular. The spines can vary in shape and size depending on the species.
• Pedicellariae: These are small, pincer-like structures found on their body surface, which help them to clean their bodies and capture prey.

Environments

Ophidiasteridae starfish are primarily found in shallow, tropical and subtropical waters. They are commonly associated with coral reefs, seagrass beds, and rocky shores. These environments provide them with ample food sources, shelter, and opportunities for reproduction.

Diet and Feeding

Ophidiasteridae starfish are carnivores and opportunistic feeders. Their diet consists of a variety of invertebrates, including:

• Corals
• Sponges
• Bryozoans
• Mollusks
• Sea anemones

They use their long, flexible arms to reach into crevices and under rocks to capture prey. Once they have captured their prey, they use their tube feet to bring it to their mouth.

Reproduction

Ophidiasteridae starfish reproduce sexually. They release sperm and eggs into the water, where fertilization takes place. The larvae are free-swimming plankton and spend several weeks in the water column before settling onto the seafloor and transforming into adults.
