Nemertesia norvegica is a species of hydroid, a type of colonial animal, belonging to the family Plumulariidae. These animals are commonly found in marine environments, particularly in the North Atlantic Ocean.
Description & Characteristics
Nemertesia norvegica typically grows to a maximum length of about 10 cm. It has a slender, branching structure with small, polyp-like individuals called hydranths that are responsible for feeding. The colonies are often attached to seaweed or other substrates.
Habitat and Occurrence
Nemertesia norvegica is a common species in the North Atlantic Ocean, primarily found in the neritic zone, which extends from the shoreline to the edge of the continental shelf. This species is often found attached to various substrates, including seaweed, rocks, and piers, indicating its adaptability to different environments.
Taxonomy
Nemertesia norvegica is classified within the phylum Cnidaria, class Hydrozoa, order Leptothecata, and family Plumulariidae. This classification highlights its close relationships with other hydroids and its distinctive features within the broader group of cnidarians.
Feeding
Like other hydroids, Nemertesia norvegica is a carnivorous species, feeding primarily on small planktonic organisms. The hydranths of the colony use stinging cells called nematocysts to capture and paralyze their prey.
