It is generally assumed that plankton of the open seas—regions which exhibit relatively constant high salinities—are stenohaline. This paper reports a preliminary investigation of the tolerance of Caribbean and and South Atlantic marine zooplankton to both increases and decreases in salinity. The majority of forms studied will withstand salinity changes much greater than they would be expected to encounter in their normal environment, thus suggesting that salinity may not be a limiting factor in their distribution. The forms studied are listed in the order of their ability to resist salinity change.
