Nota: For Gurney (p.147), 5 species of Acrocalanus have been recorded from the Red Sea, but only one of them, A. gibber, from the Gulf of Suez and none from the Canal; in the abundant material examined from Suez and various points in the Canal, only one species is distinguishable, which, in spite of great variation in size and some variability in form, must certainly be regarded as A. gibber. All females are characterized by having a strikingly humped dorsal outline and a partial separation of the head from the 1st thoracic somite (2 characters which separate A. gibber from the others described (Wolfenden, 1908). Wolfenden states that the A1 of A. gibber does not reach the end of the abdomen; but Giesbrecht describes it as extending beyond by 1 to 2 segments, while in the Suez specimens it always exceeds the furca by 1 to 3 segments.
In size the Suez Canal specimens are very variable, ranging from 0.74 mm to 0.98 mm. The smallest specimens are from station R.3, where the maximum size was 0.82 mm while at Port Taufik (near Suez Bay) it ranged from 0.85 to 0.98 mm. In the Bitter Lakes the length was about 0.86 mm.
Adult males appear to be exceedingly rare in this genus, but not in the Suez specimens.
After moult, in the adulut male, the dorsal outline becoming evenly rounded, the line of division between head and thorax disappearing, and the abdomen becoming 5-segmented. The A1 become modified, the basal segments fusing together into a thickened part provided with numerous aesthetes, only 18 segments being visible; they are shorter than the abdomen. The P3 differs from that of the female in having marginal spines on the distal part of the exopodal segment 3, and the spines on the distal part of the exopodal segment 3 of P4 are smaller and more numerous. The P5 on the left side is long and slender, 5-segmented, the basal segment swollen and the rest of the limb bending almost at right angles to it. The terminal segment has a single short seta.
The length 0.85 to 1.06 mm.
The differences between male and female are so great that it would be difficult if not impossible to attach them to their appropriate species if more than one species was present. For tghis reason A. gardineri Wolfenden cannot be maintened as a different species, since Wolfenden had males only, apparently taken from the same collections as contained other species of female, and also immature males of those species.
A. pediger Cleve is a doubtful species. Carl (1907) has pointed out that the male described as belonging to A. pediger is actually the male of a Paracalanus to which he gives the name P. clevei, while Sewell (1914) claims it as the male of P. aculeatus. The female of A. pediger is actually the immature male, probably of A. gibber (Sewell, 1914)

Nota: The same sampling procedure was used for all cruises. Zooplankton samples were collected by vertical tows from 3 m of the bottom to the surface (plankton net : 505 µm mesh size).
The aim of the research is the relationship between copepods and associated water masses in the southern Taiwan Strait.
