Group sweeping: Feeding activity and filtration rate in the tubiculous amphipod Haploops nirae (Kaim-Malka, 1976)

► We investigated feeding ecology of crustacean tubiculous amphipod Haploops nirae. ► Retention efficiency showed that particles larger than 20 µm ESD were 100% retained. ► The individual clearance rate was 14.6 ± 0.4 mL·h− 1.ind− 1 or 25.2 ± 0.7 L·h− 1.gdw− 1. ► The feeding activity revealed an adaptation to feed under turbid conditions. ► Haploops filter a volume of water equivalent to the whole bay in 29-30 days.
