63 Amphiprora sulcata 具槽繭形藻 Phylum: Heterokontophyta 门：不等鞭毛門 Class: Bacillariophyceae 纲：羽紋硅藻綱 Order: Naviculales 目：舟形藻目 Family: Amphipleuraceae 科：雙肋藻科 Morphology Cells are roughly rectangular in girdle view and strongly constricted in the middle, with biarcuate wings on both sides. Keel separation line is weakly biarcuate and valves are finely striated. Transapical striae are slightly curved in the middle, divergent from central nodule, becoming parallel towards apices. Single large elongate chloroplast with wavy edges lies in the center. 形態 細胞整體呈近似矩形，在中間明顯內凹，兩側以中間為界各具兩個半橢圓形的翼。 龍骨分界線輕微半圓形。殼面具有條紋。切頂軸的條紋在中間彎曲，從中間位置分 兩側朝向切頂軸方向平行分佈。色素體較大較長，單個，具波浪狀邊緣，位於中間 位置。 Ecology and distribution Amphiprora sulcata is a benthic species in warm coastal areas. Cells could be epiphytic or found in both sediment and water. 生態與分佈 具槽繭形藻是底棲物種，分佈於較暖的近岸。細胞可以附著生存，在水體、沉積物 均有發現。
