By alkaline comet assay primary DNA damage was assessed and cytotoxicity by fluorescent staining. Norflurazon at 0.61 mg L\u2212\u20091\u00a0significantly increased DNA damage in brown hydras compared to the control (6.17\u2009\u00b1\u20090.6\u00a0\u03bcm, 5.2\u2009\u00b1\u20091.7% vs. 2.9\u2009\u00b1\u20090.2\u00a0\u03bcm, 1.2\u2009\u00b1\u20090.2%). Cytotoxicity was significantly elevated, being higher in brown hydras (25.7\u2009\u00b1\u20093.5% vs. 8.2\u2009\u00b1\u20090.2%). UV-B irradiation induced significant DNA damage in brown hydras (13.5\u2009\u00b1\u20091.0\u00a0\u03bcm, 4.1\u2009\u00b1\u20091.0%). Simultaneous exposure to UV-B and norflurazon led to a synergistic DNA damaging. The frequency of cytotoxicity and hedgehog nucleoids was more pronounced in brown (78.3\u2009\u00b1\u20099.4%; 56.4\u2009\u00b1\u20096.0%) than in green hydras (34.7\u2009\u00b1\u20092.5%; 24.2\u2009\u00b1\u20090.6%).
