Siphonophora of the Gulf of Aqaba (Red Sea) and their associations with crustaceans

Numerous studies have been carried out on marine taxa of the Gulf of Aqaba region, but fewhave concentrated on gelatinous zooplankton. Here, a new collection of pelagic hydrozoansiphonophore species is described from a study made during December 2013, whilstsnorkelling along the Israeli coast of the Gulf of Aqaba to a depth of 5 m. Ten species wereidentified, including two species present in both post-larval and adult life stages. Fourspecies are first records for the Gulf, and almost all the specimens collected were found tobe associated with one or more hyperiid amphipod crustaceans or phyllosoma lobster larvae.Two of these crustacean species (Thamneus rostratusandPhronima colletti) are first recordsfor the Red Sea region, a third (Parascelus edwardsi) was previously observed in this area, butnot in the associations here recorded, and a fourth (Palinurellus wieneckii) is found to haveundergone a northward extension of its distributional range. Moreover, our observation ofP. wieneckiiphyllosoma larvae attached to colonies ofAgalma okeniiconstitutes the firstevidence of palinurid (spiny lobster) association with siphonophores. The siphonophore taxafound in this study and those from previous studies are tabulated, and species richnessdiscussed in relation to species lists published from other recent tropical studies worldwide.The hyperiid amphipod taxa identified are also tabulated and discussed in relation to thenature and possible means of invasion of gelatinous host siphonophores by crustaceans.
