Developmental toxicity of Calothrix 33−2 extracts. Within 4 dpf, zebrafish embryos exposed at 4- to 32-cell stage to 100 μg/mL chloroform extracts of Calothrix 33−2 (B) show morphological deformities, including pericardial and peritoneal edemas, as well as bent tails/body axes, compared to control embryos treated with solvent (i.e. CHCl3) only (A).
