Mudskippers are fish that have evolved to live part of their lives out of water. They belong to the family Gobiidae and live tropical mangrove forests through Australia, Asia and parts of Africa.
During low tide they emerge from burrows to spend hours moving about the muddy tidal flats. Their front fins have evolved into robust primitive ‘legs’ which, in combination of their powerful tail, allow them to walk and skip across the slippery mud flats. They even climb on mangrove roots where sucker-like disks on their abdomens that let them to cling to the roots. Their eyes have also modified to sit on stalks that give all-around vision. Their gills are housed in an enlarged chamber where they can store water and air and as long as the gills remain moist, they can ‘breath’ out of water, the gills acting like a type of primitive lung. They can also absorb oxygen through parts of their skin.
During high tide, they retreat to vertical U-shaped burrows in the soft mangrove mud. As the tide comes in the mudskipper gulps air and retreats several times into the burrow and expels the air into the terminal end of the chamber. This provides it with the right mix of air and water it needs during high tide.
They feed on a variety of insects, small crustaceans and marine worms. They are highly territorial with males defending a territory around their burrows. The eggs are laid by the female in funnel-shaped ‘nests’ among the mangroves, and when the young hatch they resemble normal fish. After a period of time the eyestalks develop and the young progressively leave the aquatic nesting area to adopt their amphibious way of life among the mangroves.
Six species of mudskipper live in the mangroves of northern Queensland, most belonging to the genus Periophthalmus, but I couldn’t identify which species this one from Magnetic Island was.
Fascinating animals and I though this one (about 6cm long) with his emerald eyes was worth sharing with you, hope you like it

Very interesting fish (? animal?) and great note. You've managed to show the well-camouflaged features very well against the background, and its emerald eye certainly stands out.

Chris, Cool lookin' creature here..Good details and colors and those emerald eyes are very striking..Looks like a cross between a fish, a frog and a salamander! Well done and TFS!

Halo Chris!
Great photo. I'm a little scared because of it. But superb subject and great POV!

Amazing camo against the mud.
Excelent shot and well done on the composition.

Mike

Chris, this is one of most fascinating animals. I saw many interesting programms abot in on science channels but never saw it in real life. Your picture is superb. Composition, details, quality - all excellent but emerald eye makes the picture!

Great shot Chris,
I was watching a documentary on these just 2 days ago.
Excellent detail and colours (especially the eye)
Good composition. The notes are excellent.
Thanks for posting

I Chris! I liked very much to see this one. It must be a real nightmare to get some contrast here :D It looks like the BG. You did a good job. Thanks.

Fascinating animal. What incredible camouflage. Yet that amazing color in the eyes that definitely would attract attention. Very crisp details and good light under water. Great job! Thanks for sharing about this unusual fish. : )

Another interesting critter. Wish i could actually see these guys in the wild though. Very nice eye details. Very well done, Chris.
