Common Names

There are no widely recognized common names for Paralepidonotus worms.

Characteristics

Members of the genus Paralepidonotus share several key characteristics:

  • Flattened body: Their bodies are typically dorsoventrally flattened, allowing them to move easily through sediment and under rocks.
  • Numerous scales: They possess a large number of overlapping scales (elytra) that cover their dorsal surface. These scales are often ornamented with various patterns and textures.
  • Protruding antennae: They have prominent antennae that project from the head region, which are thought to play a role in sensory perception.
  • Parapodia: Like all polychaete worms, they have parapodia, fleshy appendages on each body segment that aid in locomotion and respiration.
  • Small size: Most Paralepidonotus species are relatively small, typically measuring less than a few centimeters in length.

Environment

Paralepidonotus species inhabit a variety of marine environments, primarily in the deep sea:

  • Deep-sea sediments: They are often found burrowing in soft sediments on the seafloor.
  • Coral reefs: Some species may occur in association with coral reefs, particularly in deeper water habitats.
  • Hydrothermal vents: Several species have been recorded in hydrothermal vent environments.
