In Malaysia Pn. It probably feeds on small invertebrates. Its behaviour is completely unknown. Synonyms: Euchoristopus kalolo regius , Periophthalmus dipus , Periophthalmus sobrinus , Periophthalmus vulgaris Maximum recorded size: 93 mm SL.
Sexual dimorphism: None known. Body colouration: Body background colour brownish to dark grey on dorsum and sides, ventrally whitish; head ventrally white; many small white speckles on cheeks, opercula and sides of body; silvery vertical stripes on flanks, ventrally more evident; dorsal dark brown saddle-like irregular bars, may also be visible. Fin colouration: First dorsal fin with a reddish brown background, a wide black to dark brown stripe below margin, darker in the anterior portion, and many small white spots below it; margin white to transparent; second dorsal fin with a transparent background, a black medial stripe, irregular brownish speckles proximally on rays and membrane, and an orange margin; caudal fin dusky, with series of dusky to brownish speckles along rays.
Distribution: The Silver-lined Mudskipper is the most widespread mudskipper species, presently known from East Africa eastward to the entire Indo-Pacific region, to the Samoa and Tonga Islands, southern Japan and eastern Australia. This species is particularly popular in southern Japan. It is usually found nearby water at low tide, frequently nearby the mangrove marine fringe, but it apparently is an extremely adaptable species, and different populations are found in different environmental conditions.
A very territorial species: aggressive and agonistic behaviours are frequently observed. Males jump to attract females into burrows. Burrows typically have two main turreted openings. It feeds on small invertebrates. Its behaviour was studied in East African and Malagasy populations.
Synonyms: Gobius barbarus , Gobius koelreuteri , Periophthalmus papilio , Periophthalmus erythronemus , Periophthalmus gabonicus Maximum recorded size: mm SL. Body colouration: Background colour dark brown to greyish on head, dorsum and flanks, ventrally whitish; sky blue speckles on flanks, which are larger and more numerous on snout, cheeks and opercula; several black to dark brown irregular saddle-like diagonal bars may be visible on dorsum.
Fin colouration: First dorsal fin membrane dark brown, with a black to bluish band below margin, sandwiched by a narrow and broken whitish-blue stripe and a narrow transparent margin; completely black in some specimens.
Second dorsal fin background brown, with a medial black stripe sandwiched by two white stripes, and a brown margin. Caudal fin dusky, with series of dark brown speckles along rays in some specimens; anal fin from whitish to brownish with a yellowish margin; pelvic fins dark brown on dorsal side; pectoral fins dusky.
If a mudskipper comes from this region, either it is a new species, or it is Periophthalmus barbarus. In Nigeria, its diet apparently includes algae in the dry season. In this region, it is found in mangrove and Nypa palm Nypa fruticans forests, and has consequently been included on lists of endangered species due to the high level of coastal environmental degradation in this area.
Periophthalmus gracilis Eggert, ; Slender Mudskipper. Synonyms: None. Maximum recorded size: 45 mm SL. Sexual dimorphism: Mature males and females have differently coloured dorsal fins; see below. Body colouration: Body ground colour dorsally and laterally grey, ventrally white; white irregular blotches on ventral side of head and vertical iridescent bluish stripes on flanks; diagonal, irregular saddle-like dark brown bars on dorsum.
Fin colouration: First dorsal fin with transparent background, with a faint greyish infra-marginal stripe, medially yellowish in mature males, and a large black blotch posteriorly, covering the last spines; in some specimens, black spots may be present between spines; second dorsal fin with a transparent background, grey spots on proximal membrane and a medial dark stripe; a reddish margin is present in mature males; membrane of caudal fin and pectoral fins transparent, with series of dark speckles on rays.
It is frequently imported from Singapore and Thailand. It is one of the smallest mudskipper species. It lives inside mangrove forests; at higher levels, reached by tides only intermittently; it is frequently found around tide pools or the openings of burrows made by the Giant Mudskipper, Periophthalmodon schlosseri. It feeds on small invertebrates, but otherwise its behaviour is almost completely unknown.
Periophthalmus novemradiatus Hamilton, ; Indian mudskipper. Maximum recorded size: 51 mm SL. Sexual dimorphism: The first spine of the first dorsal fin is highly elongated on males, reaching the second dorsal fin if pushed down. Body colouration: Body ground colour dorsally and laterally grey to pale brown, whitish on venter; white speckles scattered on flanks, denser and rounded on opercula and cheeks, interspersed with smaller dark dots only on flanks; speckles on cheeks can become sky blue; diagonal, irregular saddle-like dark brown bars may be visible on dorsum.
Fin colouration: First dorsal fin membrane with a white margin, red between the first spines, with brown diffused blotches in the distal portion, hyaline to grey for the rest, and with white flecks parallel to the spines in some specimens; spines not pigmented; second dorsal fin with a dusky translucent background, white margin, a large dark grey inframarginal stripe, a medial dark stripe and coalescent dark grey spots on the proximal membrane; membrane of caudal fin and pectoral fins dusky, darker along rays.
Pelvic fins dorsally pigmented and with a white margin. Pelvic fin shape: Pelvic fins are fused by a basal membrane for more than half the length of the inner pelvic rays, and a strong pelvic frenum is present Fig. Its behaviour and ecology are largely unknown.
Periophthalmus variabilis Eggert, ; Dusky-gilled Mudskipper. Maximum recorded size: 65 mm SL. Body colouration: Body ground colour dorsally and laterally brown, ventrally whitish to grey; edge of the gill cover posteriorly blackened; head and trunk with numerous dark brown blotches, larger on trunk; tiny iridescent bluish speckles on cheeks and flanks; diagonal, irregular saddle-like dark brown bars on dorsum.
Fin colouration: First dorsal fin with a transparent background with proximal red spots between elements, a greyish stripe below margin, anteriorly darker, and a translucent margin; second dorsal fin with a proximal series of reddish-brown spots, a dark stripe below margin, and a yellow margin; caudal fin membrane dusky, rays distally orange with series of brownish speckles; pectoral fins distally orange.
Pelvic fin shape: Pelvic fins are fused by a basal membrane for less than half the length of the inner pelvic rays, and a strong pelvic frenum is present Fig.
Distribution: The Dusky-gilled Mudskipper is distributed across Southeast Asia, and is frequently imported from Singapore, together with Periophthalmus gracilis. It is a relatively terrestrial species found inside mangrove forests, being more abundant inland, and less abundant closer to the sea. It is also found in the high supra-tidal zone, where sea water submerges the substrate only on a few days each month during the very highest tides.
It hides well on the forest floor, moving only at the very last moment when approached. Its behaviour is almost completely unknown. References Clayton D. Diesselhorst G.

How long can Mudskippers stay out of water? Clingfish can leave the water and breathe air stored in their gills. They can survive up to 3 and a half days out of the water. Gobies: Gobies, suck as mudskippers , are a truly amphibious fish. Rober Schlemmer Pundit. Is Turtle considered meat? Is turtle , meat or seafood? Turtle is seafood according to the Catholic Church, but you probably should be careful if you're a real hard-liner, because a lot of places will substitute veal in turtle soup, which is clearly not a seafood.

Do Mudskippers taste good? Ilhem Eleiciaga Teacher. How many fish are killed each day? Wild fish. Kellye Hildeberto Supporter. Where do you find Mudskippers? They live in swamps and estuaries and on mud flats and are noted for their ability to climb, walk, and skip about out of water. Elongated fishes, they range up to about 30 cm 12 inches long. Debera Fayolle Supporter. What do Mudskippers eat in the wild? Periophthalmus barbarus is an omnivore.
In the wild , mudskippers prefer to eat worms, crickets, flies, meal worms, beetles, small fish, and small crustaceans sesarmid crabs. Mudskippers kept as pets can eat frozen fare such as bloodworm or artemia and flake. By subscribing, you can help us get the story right.
