വളരെ ചെറിയ ഒരു ശുദ്ധജല ജീവിയാണ് . ഹൈഡ്രയെ ഒരു മാംസഭുക്കായാണു കണക്കാക്കുന്നത്. <ref>Gilberson, Lance (1999) ''Zoology Lab Manual'', 4th edition. Primis Custom Publishing.</ref><ref>Solomon, E., Berg, l., Martin, D. (2002) ''Biology'' 6th edition. Brooks/Cole Publishing.</ref>ശുദ്ധജലത്തിൽ കാണപ്പെടുന്ന ചെറു ഷഡ്പദങ്ങൾ അവയുടെ ലാർവകൾ എന്നിവയാണു പ്രധാന ഭക്ഷണം. പ്രായം ആക്കുകയോ പ്രായാധിക്യത്താൽ മരണപെടുകയോ ചെയ്യാറില്ലാ ഇവ. ഇവയുടെ കേടുക്കൾ സ്വയം ഭേദമാകുന്ന രീതിയും ശ്രദ്ധേയമാണ്.
