It is the first feature of P. chrysospilos, conspicuous golden spots appear in the entire body even if body color changes variously.

Body color changes largely with the circumstance of that time. Body color seems to become whitish when they are active at low tide, i. e., feeding and migrating. In contrast, they are dark body (see right picture), when they rest during high tide.

It is visible that it is many golden spots in the cheek.
When sun shines, especially it is conspicuous well.
Round pelvic fins

disk condition is feature.
Because the ? it is roundly is, adsorption power is very strong,
Even on the driftwood of the place where it has the flow
Long haul you have been able to have adhered.

Periophthalmus chrysospilos is very nimble!
P.chrysospilos to be many in the tideland which confronts in the flow and the sea of the big river seeing, very long distance moves. It is the extent which can be active at the place where sight you opened, courtship conduct and the like it can observe even from the distance.
At the place where I observe, when the tide pulls, it escapes to the sea, lifts the face and being to be many a thing which swims it does, but when the tide has been full, chasing, without escaping to water side, in order to try to escape to the land, it seemed that feels tidal period.

Crowding in the place where, ???? and the animal plankton when they are 10 centimeters in depth of water from the river edge have grown in large quantities, while swimming, in order the ? to shirk, you eat.
To be tremendous we are skillful the standing swimming.


It moves and very Satoshi the ? arm, migration length is very long, is. Liking in the water, while it increases the head it can also swim long.

It is empty, but very hateful it dries, somewhere of the bodies has gone in the water the favorite the appearance where.
It was observed well that you have gone to bed with the form where the caudal fin has entered into water.
Although being the fish, while it lifts the faceyou cannot call the place where you swim at all...
So also the original ? being quick, trying probably to scoop with the net even when,
By driving force of tail ??
The water surface it keeps leaping.
(Intently, to the sea to the sea on the move) the ?

The tide pulling, when the tideland of the big mud appears,it movesP. chrysospilos to the direction which the tide pulls with the group. And, the tied pool (after the tide pulled, the puddle which remains) it is in, the ? you shirked ???? and the juvenile shrimp and ate.
