Through Species, Fresh water and Abdomen
Harpacticoids are distinguished from other copepods by the presence of only a very short pair of first antennae. The second pair of antennae are biramous, and the major joint within the body is located between the fourth and fifth body segments. They typically have a wide abdomen, and often have a somewhat worm-like body.
