The sessile or polyp stage ofChrysaora quinquecirrha, the sea nettle, is likely to be found in Chesapeake Bay and its tributaries on the hard substrates wherever salinities from 7 to 20% occur.From experimental studies in field and laboratory, we found that the planulae, larval stage of the sea nettle, set on oyster shells which were placed off the CBL pier and in St. John Creek; that planulae set more … Broadcasting of chemicals on the bay bottom in an … When most Marylanders think of jellyfish, they picture Bay beaches surrounded by globes of milky-white — and stinging — sea nettles.
