Polygordius appendiculatus is a species of segmented worms in the family Polygordiidae. They are surficial modifiers. Individuals can grow to 4.5 cm. They rely on anguilliform to move around.
Definition: overall repetitive or reflective pattern in the body of one individual of this taxon. eg: bilateral symmetry, rotational symmetry, radial symmetry
Definition: Living in the fluid medium (water or air) but unable to maintain their position or distribution independently of the movement of the water/air mass (adapted from Lincoln et al., 1998).
Definition: directly or indirectly modulating the availability of resources to other species, by causing physical state changes in biotic or abiotic materials; modifying, maintaining and/or creating habitats
Definition: The marine benthic biome (benthic meaning 'bottom') encompasses the seafloor and includes such areas as shores, littoral or intertidal areas, marine coral reefs, and the deep seabed.
Definition: A group of species that exploit the same food resources, and/or use the same feeding or foraging methods. http://en.wikipedia.org/wiki/Guild_(ecology)
Definition: consumers specializing in labile organic matter, which is easily metabolized; usually low molecular weight compounds, eg: simple sugars or proteins. For instance, metabolic scaling puts intense selective pressure on small organisms to ingest foods rich in labile organic matter; the residence time in a very short gut is too brief for enzymatic hydrolysis, so they specialize in rapidly metabolizable compounds.
