ABSTRACT
Usually, suspension feeding holothurians are considered as passive suspension feeders because they depend exclusively on ambient water movements. In general, suspension feeders, and in particular passive suspension feeders, have structures (tentacles, tube beet, arms, etc.) that enhance the rate of particle capture by changing the scale of turbulence in the water, in terms of the number of Reynolds. As more long are the filtration structures, more turbulent became the flux.
