Grazing of two common appendicularians on the natural prey assemblage of a tropical coastal ecosystem

Trunk length 0.7 ± 0.2 for O. longicauda and 0.8 ± 0.2 for O. fusiformis. House length 3.9 ± 0.5 mm vs 7.0 ± 1.3, respectively. Clearance rate 35 and 39 ml/ind/h respectively. “The mean clearance rates of these 2 species on total sub-micron cells in Kaneohe Bay were not significantly different; however, O. fusiformis cleared Hbact at a marginally higher rate”
