The Blue-spotted Mudskipper (Boleophthalmus boddarti)
is a large species that can be found in Sungei Buloh Nature Park. Slightly smaller than the Giant Mudskipper, they are still quite impressive at up 22cm long. The distinctive blue chevron markings instead of two lines down their body makes them easy to identify.

Maybe not the sharpnest image, I was on full zome and this is cropped heavily, but a worthwhile post I think.

These mudskippers are vegetarians and graze on algae and other titbits that are left behind by the tide on the mudflats. They harvest this by skimming the mud surface with side-to-side movements of their heads.

They have a more vigorous courtship than the Giant Mudskipper. The males attract females by leaping into the air, raising their colourful dorsal fins at the peak of their acrobatic flip.

Mudskippers are found along the intertidal zone, living happily on the margin of land and sea. They have special adaptations to help them dominate a habitat which few other animals can exploit: soft mud with fluctuating water quantities and qualities.

How do they breathe on land? Underwater, mudskippers breathe through gills like other fishes. However, unlike other fishes, mudskippers can't stay underwater indefinitely. Other fishes asphyxiate when taken out of water because their gill filaments stick together and cannot absorb gaseous oxygen. Mudskippers can retain water in enlarged gill chambers which lock shut on land. Sort of reverse scuba gear, to keep their gills remain moist on land. They rotate their eyes to swill the water in the gill chambers around and keep the gills fluffed up and oxygenated.

Mudskippers can actually breathe air. They can absorb gaseous oxygen through blood-rich membranes at the back of the mouth and throat (buccopharyngeal cavity). They also absorb air through their skin which is rich with blood capillaries, so long as the skin remains moist. This is why they often roll in puddles and keep their tails in water, leading some early observers to believe that mudskippers breathed through their tails! Mudskippers also have to regularly replenish the water in their gill chambers so they cannot stay far from water. Giant Mudskippers have among the best land-adapted gills: shorter filaments reinforced with rods so they don't collapse easily out of water.

Do they walk? Mudskippers have arm-like pectoral fins which even have little "elbows". But they do not move these alternately in the way that we walk. Instead they make little hops by keeping their body rigid and jerking forwards on their pectoral fins; called "crutching" because the movement is similar to that of a person on crutches. They leave typical trails on the mud (right).
