在实验室测试中，在新西兰南岛凯库拉半岛附近采集的蜘蛛蟹Notomithrax ursus被某些种类的藻类所掩盖。最适合作为掩蔽材料的藻类类型是支藻，如盐翅藻和珊瑚。像Ulva sp.这样的Thallose - like藻类和像Cladhymenia oblongifolia这样的带状藻类不太受欢迎。研究还表明，熊氏奈瑟菌喜欢掩盖的藻类也是熊氏奈瑟菌喜欢吃的藻类。讨论了掩蔽和食品储存的相互矛盾的要求，以及选择藻类的可能原因。
Abstract In laboratory tests, the spider crabs Notomithrax ursus, collected near Kaikoura peninsula, South Island, New Zealand, were shown to mask with some species of algae more than others. The types of algae most preferred as masking material were branched algae such as Halopteris spicigera and Corallina officinalis. Thallose‐like algae such as Ulva sp., and strap‐like algae such as Cladhymenia oblongifolia, were less preferred. It was also shown that algae with which N. ursus prefers masking are also the algae that N. ursus prefers to eat. The conflicting requirements of masking and food storage, and possible reasons for algal choice are discussed.
