Partner choice is an important selective force in mutualistic partnerships. Although several aspects of mutualism have been well-studied, partner choice remains a novel aspect in the study of marine mutualists. Previous research on the goby-shrimp mutualism suggested that visual cues affect the ability of gobies to discriminate between potential shrimp(More)
The current concept of Periophthalmus novemradiatus (Hamilton, 1822) includes two species. Procurement of fresh material and examination of extant type specimens revealed that P. novemradiatus differs from P. variabilis Eggert, 1935, primarily in the number of anal fin rays (I, 12 or 13 vs. I, 10-12); the lateral scale series (62-67 vs. 48-60); the extent(More)
Addressing transboundary environmental problems, such as pollution, and climate change, hinge on strategies that often require both mandatory and voluntary participation of affected nations. Using an unprecedented approach, the Singapore government recently passed a Transboundary Haze Pollution Act (THPA) that financially penalizes companies for smoke-haze(More)
The mudskipper Periophthalmus walailakae is recorded from Singapore, where it was previously misidentified as Periophthalmodon schlosseri, with which it is syntopic. Periophthalmus walailakae is distinguished from its congeners by the following combination of characters: pelvic fins completely united and shaped like a disk, and first dorsal fin dark brown(More)
A new species of mudskipper (Gobiidae: Oxudercinae) from northern Australia is described. This species was previously misidentified as P. takita [corrected] Eggert, 1935 . Periophthalmus takita sp. nov. can be distinguished from its congeners by the following suite of characters: modally VIII spines in the first dorsal fin; second dorsal and anal fins with(More)

Walter Bruno Eggert described nine species and fifteen subspecies of the oxudercine genus Periophthalmus in 1929 and 1935. His descriptions were based primarily on specimens collected by Jürgen Wilhelm Harms during several expeditions to South-east Asia and Japan. The whereabouts of many of the type specimens were unknown, and were presumed destroyed during(More)
