Crab-eyed goby

The motion of this goby is interesting.When a predator approaches,this goby raises the dorsal fins to flash the "eyespots" of them and waves the ventral fin and moves like a lage sideways-moving crab.
It's easy to take profile photos for it moves sideways so the distance doesn't change.But when taking heads-on shot , it's too difficult ! It never cease moving front and in rear !
