Effect of petroleum-related pollutants on Aurelia growth and development. Progress report, September 12, 1977--November 15, 1978
Strobilation initiation studies revealed that phenol and aniline inhibited strobilation initiation and phenol (at lower dosages) caused a reversal of strobilation initiation whereas benzo(a)pyrene did not affect this process. Ephyra abnormalities were created by phenol (abnormal pulsing and a cup-shaped morphology) naphthalene (abnormal lappet formation) and aniline (impaired nematocyst synthesis). Statolith synthesis was reduced by aniline, naphthalene, phenol, and benzo(a)pyrene. Budding rates were likewise retarded by phenol and aniline as was the metamorphosis of planulae into polyps. Tentacle regeneration of mature polyps was not affected by phenol or aniline. A specific testing procedure for the administration of the water insoluble hydrocarbons was developed using sonication. The hydrocarbons were reduced to very fine particles with sonication and the minute particles were taken into the jellyfish. New jellyfish cultures were developed from medusae collected in Norfolk. These organisms responded to iodide, thyroxine, and hydrocarbons in a similar manner as the Texas Aurelia. The hydrocarbon effects on strobilation initiation and ephyra formation suggested that the hydrocarbons affected thyroxine synthesis and/or action in the jellyfish (and other organisms) and call for detailed studies as to their specific mechanisms of action.
