Diopatra sugokai is a species of marine worm belonging to the family Onuphidae, commonly known as the “sand-mason worms” or “beard worms.” These worms are characterized by their distinctive tube-dwelling lifestyle and their ability to construct intricate burrows in the seabed.
Description & Characteristics
Diopatra sugokai exhibits a characteristic elongated, segmented body structure typical of polychaetes. The worm possesses a distinct head region with a pair of well-developed palps used for sensing and feeding. Its body is further adorned with numerous parapodia (paired, fleshy appendages) that aid in locomotion and respiration. The size of Diopatra sugokai can vary depending on factors such as habitat and food availability, with a maximum recorded length of approximately 10 cm.
Habitat and Occurrence
Diopatra sugokai is typically found in intertidal and shallow subtidal zones, inhabiting sandy or muddy sediments. This species is predominantly associated with marine environments, with a depth range extending from the intertidal zone to depths of around 20 meters. Its preference for sandy substrates makes it a common inhabitant of coastal environments and estuaries, often found in areas with moderate wave action and abundant food sources.
Taxonomy
Diopatra sugokai is classified under the phylum Annelida, belonging to the class Polychaeta, order Eunicida, and family Onuphidae. This taxonomic classification places it within a diverse group of marine worms, with a significant number of species found in various marine environments across the globe.
Feeding
Diopatra sugokai is a carnivorous worm, relying primarily on a diet of smaller invertebrates and organic matter. Its feeding strategy involves extending its proboscis (a fleshy, extensible mouthpart) out of its burrow to capture prey. The proboscis is equipped with sharp teeth and a strong muscular structure, enabling it to effectively grasp and consume its food. Diopatra sugokai‘s dietary preferences play a crucial role in the ecological balance of its marine habitat.
