How do they breathe out of water? While out of water, they breathe by retaining water in enlarged gill chambers. Just as we bring tanks of air to breathe from when we scuba dive, mudskippers bring stores of water. They can also breathe air through their wet skin. These fish are in fact more comfortable crawling around on the mud than submerged in water!

Mudskippers have interesting features designed to rule the mud! They have eyes at the top of the head for an all-round view. While their mouth faces downwards to feed on the mud surface. In some mudskippers, the pelvic fins are fused to form a sucker so they can better cling to rocks and roots. Their pectoral fins are used like crutches to crawl over mud. Some have colourful dorsal fins that can be raised to signal other mudskippers on the sand or mudflats.

They curl their muscular body sideways then push against the mud to spring forward.
