Abstract

Despite their important functional role in marine ecosystems, we lack much information about jellyfish, including basic research on their swimming behavior.Here we used acoustic telemetry to obtain detailed behavioral data on 2 scyphozoans, lion's mane jellyfish Cyanea capillata and fried-egg jellyfish Phacellophora camtschatica, in Hood Canal, Puget Sound, Washington, USA.Individual variation was high in both the short-term (hours) and long-term (days) data, although several patterns of behavior emerged.Lion's mane jellyfish performed diel vertical migrations over the longer time period, but their depth did not vary with tidal stage.Additionally, horizontal swimming speeds varied with diel period and tidal stage for both lion's mane and fried-egg jellyfish.Lion's mane jellyfish swam faster during the night than day, whereas fried-egg jellyfish swam faster during the day.Both species had the highest swimming rates during flood tides.Jellyfish clearly exhibited active swimming behaviors and were not passively planktonic.Net and cumulative distances traveled suggest that Hood Canal may be a sink for jellyfish, potentially exacerbating effects of population blooms on the ecosystem.Our findings provide mixed support for previous studies reporting diel vertical migrations in other jelly fish species, and provide evidence that jellyfish are capable of more advanced swimming behaviors than often thought.

  • A sleep-like state may not be specific to Cassiopea; other cnidarians may also exhibit it.

    “Although future studies are required to test whether other cnidarians sleep, field studies showing behavioral quiescence, diel vertical migration, and swimming speeds that vary with diel period [21,22,23,37] suggest that a sleep-like state may not be specific to Cassiopea.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
