An order of the Copepoda derived from the genus Harpacticus Milne-Edwards 1840, with about 1700 species known. This group of crustaceans is referred to as Podoplea Copepoda. Their form is variable but is generally linear and more or less cylindrical (see illustration). These animals are minute and vary in length from 0.016 to 0.12 in. (0.4 to 3 mm). As a rule, the first thoracic segment is incorporated with the cephalothorax, and the last thoracic segment is included in the abdomen. First antennae in the males are prehensile, while second antennae in both sexes are usually biramous.
