Pearse's Mudskipper

Periophthalmus pearsei Eggert, 1935 is a junior synonym of Periophthalmus novemradiatus (Hamiton, 1822); see Jaafar et al. (2009)

This is a sexually dimorphic species, with males possessing greatly elongate first spine of first dorsal fin, reaching eighth element of second dorsal fin when appressed; when preserved first dorsal fin brown or black with white distal edge, no spots; margin of first dorsal fin concave in males while concave to straight in females; second dorsal fin with two black bands, broader one located inframarginally and the other located medially, black spots basally on membrane between dorsal fin elements; pelvic fin with prominent frenum and inner rays fused for more than half of length. D1 modally IX; D2 modally I,12; A modally I,13; caudal fin rays modally 15 segmented rays, with first and last two rays unbranched; 62-67 lateral scale rows; 18-24 predorsal scales (Ref. 83659).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 9 - 11; Dorsal soft rays (total): 112; Analspines: 1; Analsoft rays: 12 - 13

An intertidal and amphibious air-breather that actively shuttles back and forth between rock pools and air (Ref. 31184).
