Seven harpacticoid species were found to be associated with sea ice collected during 5 Antarctic cruises of the &lt;i&gt;RV Polarstern&lt;/i&gt;. Their distribution within the fast ice and pack ice zones of the Weddell Sea is presented. Whereas some individuals probably become entrapped into the ice only accidentally, at least 4 species are genuinely sympagic. These have evolved remarkable adaptations, as evidenced by field and laboratory studies of &lt;i&gt;Drescheriella glacialis&lt;/i&gt;, which is by far the most abundant. Such adaptations include: the ability to penetrate deep into ice; a comparatively high salinity tolerance allowing it to endure large salinity fluctuations associated with ice crystal formation and melting; good swimming ability,...
