Estimated filtration rate per individual, as well as WW- and DW-specific filtration rates for Cassiopea sp. (assuming a density of 29 animals per m2), C. virginica, M. edulis, and the benthic tunicate C. intestinalis
Filtration | WW-specific | DW-specific | Population | |
rate | filtration rate | filtration rate | bulk transport | |
(Lh−1) | (Lh−1g−1) | (Lh−1g−1) | (Lh−1m−2) | |
Cassiopea sp. | 137 | 2.43 | 42.89 | 4,569 |

C. virginica | 2.61 | 0.71 | 6.41 | 1,176 |
(38, 39) | (39, 40) | (39) | ||
M. edulis | 11.9 | 0.80 | 5.94 | 3,443 |
(12) | (12, 41, 42) | (12, 42) | ||
C. intestinalis | 0.1 to 1 | 1.16 to 1.57 | 24 | 1,000 |

Rates for Cassiopea sp. are consistently an order of magnitude larger than those of bivalves. Citations refer to sources of filtration rates and size conversion factors used to calculate these values.
