Gobiiformes (Gobies) >
Oxudercidae (Mudskippers) > Periophthalminae
Etymology: Periophthalmus: Greek, peri = around + Greek, ophthalmos = eye (Ref. 45335).
Taxonomic Remarks
Eschmeyer (CofF ver. Sep. 2011: Ref. 88002) recognizes Periophthalmus cantonensis (Osbeck, 1765) as valid on the basis of Cyprinus ccantonensis Osbeck, 1865 after several publications posterior to Murdy (1989: Ref. 5218) but without mentioning the later author that we follow here, The original description must be re-assessed as there is few chances that it is a Gobiidae. See Murdy (1989) for the history of that name.

Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Intertidal, actively shuttling back and forth between rock pools and air (Ref. 31184). They breathe air when out of water (Ref. 31184). Can stay out of the water for up to 22-60 hours if kept moist (Ref. 51276). Inhabits level mudflats with no vegetation (Ref. 92840). Found in estuaries, swamps, marshy areas and tidal mud flats.
