Red Commensal Scaleworm

Arctonoe pulchra

Arctonoe pulchra is a benthic polychaete worm that can be found in the Eastern Pacific, specifically in regions such as Mexico, Peru, and the Galapagos Islands. This species typically inhabits depths shallower than 160 meters, with most occurrences recorded at depths less than 40 meters. The worm is often associated with various substrates in its environment, which may include rocky or sandy bottoms. Its appearance is characterized by a segmented body covered in scales, which helps distinguish it from other similar polychaete species. The coloration can also aid in identification during dives. In terms of diet, Arctonoe pulchra primarily feeds on organic matter and detritus, which it collects from the surrounding environment. This feeding behavior is typical of many polychaetes, allowing them to play a crucial role in the benthic ecosystem. The reproductive strategy of this species involves swarming behavior, where females release pheromones to attract males for mating. This results in the production of eggs, which may either be released into the water column or retained within protective structures. Divers encountering the Red Commensal Scaleworm may observe it in its natural habitat, often nestled within its burrows or tubes. These worms can be found at various dive sites, making them a relatively common sight for divers exploring the shallow waters of the Eastern Pacific. The conservation status of Arctonoe pulchra has not been evaluated, indicating a lack of specific data regarding its population trends.
