Harpacticoida
Her presenteres 27 arter harpactoide hoppekreps funnet i Norge.
Harpactoidene skiller seg fra de øvrige hoppekrepsene ved at de ofte er små og ved at den første antennen er svært kort. I motsetning til hos calanoidene og cyclopoidene, der forkroppen er adskilt fra bakkroppen, går forkropp og bakkropp hos harpactoidene mer eller mindre i ett. Harpactoidene er svært tolerante med hensyn til varierende miljøforhold og fins i et vidt spekter av habitater (kilder, innsjøer, dammer, huler, «rock pools», rennende vann, hule trær, jord, løv).
