Harpacticoida is an
meiofaunal group in marine sediments, after nematodes. In Arctic and Antarctic seas, Harpacticoida are common inhabitants of sea ice
. The name Harpacticoida comes from the Greek noun harpacticon (rapacious predator) and the suffix -oid (akin to) and means reminiscent of a predator .
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.[1]
