Climbing up in the mud it spits out water at a prey and sucks it back:-http://www.scientificamerican.com/article/fish-uses-water-tongue-to-grab-prey-on-land/?WT.mc_id=SA_DD_20150319-"In water, fish can use ‘suction feeding' — gulping in water to draw prey into their mouths. But on land, manipulating food near your mouth without a tongue is a trickier proposition.-"To get around this problem, mudskippers come onto land with water in their mouths. The team's videos show that as the fish approaches its prey — in the experiments, a piece of prawn on a Plexiglass plate — this water starts to protrude from the mouth. As the mudskipper's jaws envelop the target, the fish uses its water to manipulate the food.-"'First it spews out the water, then very rapidly… it's sucking the water back up again. They're using the water that is in their mouth as a substitute for a tongue,” says Michel. The results were published on March 18 in the Proceedings of the Royal Society B."
