本研究目的在於收集高雄港內海蜘蛛，以鑑種和時空分佈組成建立對海蜘蛛研究的基本資料。實驗以吊掛收集網的方式，在高雄港內設立8處測站，進行為期15個月的收集，收集到的海蜘蛛做種類鑑定並計數。
在高雄港內出現的海蜘蛛可分為4科，7屬，8個不同的種類，包含：軀幹呈圓盤狀，吻部為三角錐形的Achelia japonica；具有觸鬚以及退化螯肢的 Ammothella sp.；軀幹為圓形，但活體具有紅色斑紋的Tanystylum duospinum；頭部具明顯大螯的Callipallene amaxana、四肢粗壯的Pigrogromitus timsanus；不具輔爪的Anoplodactylus sp.1、Anoplodactylus sp.2以及頭部沒有觸鬚及螯肢的Endeis sp.。
在高雄港每月平均可獲得111.4隻個體；最優勢的海蜘蛛種類為：Ammothella sp.佔所有樣本的37.8％，最少的種類是Anoplodactylus sp.2，佔0.2％。高雄港內海蜘蛛族群在月份間變化無顯著差異，但在測站間變化則有顯著差異，Ammothella sp.、C. amaxana、Anoplodactylus sp.1與Endeis sp有顯著性別間體長差異(P<0.05)；T. duospinum以及A. echinata sinensis會有月份間體長差異(P<0.05)

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％ 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.、C. amaxana、Anoplodactylus 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).
