野外观察A.南安普顿水域[英格兰汉普郡，英国]的echinata Hodge表明，它可能以Griffithsia和Enteromorpha为食，尽管人们并不知道这种密集藻是食藻的。这种可能性是通过在14C标记的杂草上保持pycnogonid进行实验测试的，发现它们从中吸收的活性与杂草中14C的浓度成比例。实验设计排除了海水，细菌或任何被动吸收作为来源的14C的密集藻，和比较浒苔和Griffithsia消除附生植物的来源。A.刺蛾以这两种植物为食。海藻，可能在浒苔上更容易。讨论了其取食行为及其意义。
Field observations of A. echinata Hodge in Southampton Water [Hampshire, England, UK] suggested that it may be feeding on Griffithsia and Enteromorpha, although this pycnogonid was not known to be algivorous. This possibility was experimentally tested by maintaining the pycnogonid on 14C-labeled weeds, from which they were found to take up activity in proportion to the concentration of 14C in the weed. The experimental design precluded sea water, bacteria or any passive uptake as a source of the 14C in the pycnogonids, and comparisons between Enteromorpha and Griffithsia eliminated epiphytes as the source. A. echinata actively feeds on these 2 spp. of seaweed, possibly more readily on Enteromorpha. The feeding behavior and its significance are discussed.
