The goal of the present research is to collect basic data for a study on the species composition and spatiotemporal distribution of pycnogonida (sea spider) in the Port of Kaohsiung. We used collecting net to collect samples from 8 stations within the Port of Kaohsiung during a 15-month period from March 2007 to May 2008. all pycnogonids collected were identified, if possible to species level, counted, and measured.
There were eight taxa of pycnogonids in our collection belonging to four family and seven genera, including: Achelia japonica with rounded trunk and pyramid proboscis, Ammothella sp. with palp and degrade chelifore, Tanystylum duospinum with rounded trunk which bears color stripes in live specimens, Callipallene amaxana with large and functional chelifore, Pigrogromitus timsanus with robust and short walking lags, Anoplodactylus spp.1and 2 without auxiliary claws, and Endeis sp. with elongate trunk and without cephalic appendages.
The average monthly catch of pycnogonid specimens from the Port of Kaoshiung in our collection was 111.4. Ammothella sp. was the most dominant taxon, contributing to 37.8% of the total collection while Anoplodactylus sp.2 was the laest abundant taxon, amounting to only 0.2¢H of the total number. Monthly catch of pycnogonids was not significantly different between months but significantly different between stations. Significant length difference between sex was noted in Ammothella sp.¡BC. amaxana¡BAnoplodactylus sp.1 and Endeis sp(P<0.05) and significant difference in monthly body length was found in T.duospinum and A. japonica (P<0.05).
