Allometric function PR = aVb between sponge pumping rate (PR, ml min−1) and its size (V, cm3) calculated for multi-osculated specimens.
| Species | n | a | b | R2 | p | Volume range (cm3) |
|---|---|---|---|---|---|---|
| D. avara | 39 | 44.83 ± 16.27 | 0.50 ± 0.09 | 0.54 | <0.0001 | 1.5–148 |
| C. crambe | 39 | 23.88 ± 5.65 | 0.77 ± 0.09 | 0.74 | <0.0001 | 0.8–25 |
| P. ficiformis | 40 | 10.41 ± 4.48 | 0.65 ± 0.08 | 0.74 | <0.0001 | 3–420 |
| C. reniformis | 41 | 18.03 ± 7.42 | 0.61 ± 0.09 | 0.69 | <0.0001 | 3–180 |
| A. oroides | 40 | 18.52 ± 6.93 | 0.46 ± 0.07 | 0.64 | <0.0001 | 3–440 |
Data are expressed as the regression coefficient ± standard error. n is the number of specimens sampled. The probability that the exponent b is zero was <0.0001 for all species.
