Mud Skipper

Total elements in second dorsal fin 24-28 (mean = 26.8); caudal-fin length/SL 21.9-25.5% (mean = 23.6%); head length/SL 23.6-28.7% (mean = 25.8%); length of second dorsal fin base/SL 42.2-44.7% (mean = 43.6%) longitudinal scale count 103-185 (mean = 146.2); predorsal scales 48-56 (mean = 52.6).

Distinguished by the following characteristics: Total elements in D2 24-28; caudal fin length 21.9-25.5% SL; head length 23.6-28.7% SL; length of D2 base 42.2-44.7% SL; first D2 element usually un segmented and unbranched; longitudinal scale count 103-185; predorsal scales 48-56; lower jaw teeth notched (Ref. 5218).

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).

Amphibious air-breather (Ref. 31184). Lives on mud flats (Ref. 11441).

Boleophthalmus dussumieri, Dussumier's mudskipper, is a species of mudskipper native to the Indian Ocean where it can be found on mudflats in fresh, brackish and marine waters of Iraq, Pakistan and India as well as probably in Bangladesh. This species can reach a length of 18.7 centimetres (7.4 in) TL.

The specific name honours the French explorer and trader Jean-Jacques Dussumier (1792-1883).
