Acartia clausi is a species of marine copepod belonging to the family Acartiidae. This species was previously thought to have a worldwide distribution but recent research has restricted its range to coastal regions of the north-east Atlantic Ocean as far north as Iceland the Mediterranean Sea and the Black Sea with specimens from other regions assigned to different species.At just over 1 mm in length this is a generally larger animal than its closest congeners.
