Acartia hudsonica
Acartia hudsonica is a species of marine copepod belonging to the family Acartiidae. Acartia hudsonica is a coastal, cold water species that can be found along the northwest Atlantic coast.
Acartia hudsonica was originally described as a subspecies of Acartia clausi, but subsequent research concluded it is sufficiently distinct to warrant specific status. It is found in shallow coastal habitats along both the Atlantic and Pacific coasts of northern North America

Description
Acartia hudsonica anatomy is different for the nauplius (larval) stage than the copepodite (juvenile) and adult stages. A nauplius has a head and a tail, but no defined abdominal region. After six stages of molting, a nauplius develops into a copepodite, which now has a distinct abdomen. After molting six more times, a copepodite will have grown enough to be considered an adult copepod. An adult copepod is usually under 1 millimeter long. Their bodies are split up into three sections: 1. the head (cephalosome); 2. the abdomen (metasome); and 3. the tail (urosome). The head has a single eye in the center with two pairs of antenna, one long and one short. Copepods also have five pairs of swimming legs that are located on the underside of the abdomen. An anatomical characteristic that distinguish A. hudsonica from other Acartia species is blue lines on the anterior of their abdomen.
