Compared with fully aquatic gobies, these specialized fish present a range of peculiar anatomical and ethological adaptations that allow them to move effectively on land as well as in the water. Pseudapocryptes This unusual morphology creates a pectoral fin with two fin segments (the radials and the rays) and two movable hinge joints: a 'shoulder' joint where the cleithrum meets the radials and an 'intra-fin' joint where the radials meet the rays. Mudskippers are amphibious fishlike creatures that use their short muscular pectoral and pelvic fins to “walk” on mud in a series of skipping like steps, thus their name. During mating season the males will also develop brightly colored spots in order to attract females.

The West African Mudskipper is the largest of the common mudskippers that can grow up to 10 inches in length. Mudskippers in the genus Periophthalmus make popular pets and aquarists like to feed them insects, spiders and other live foods by hand.

[6] Another important adaptation that aids breathing while out of water is their enlarged gill chambers, where they retain a bubble of air. Recent research has found mudskippers don’t use their gills for oxygen exchange, but use their skin for a large part of their oxygen processing. Out of water, they breathe with air trapped in their gill chambers as well as through the skin. The authors observed sound production when male mudskippers were competing for food when held in a community tank, making preliminary recordings using a hydrophone (underwater microphone) inserted into the … Mudskipper, any of about six species of small tropical gobies of the family Gobiidae (order Perciformes). Updates? They live near the shores of in the Indo - Pacific and the Atlantic coast of Africa. Mudskippers, especially the larger kinds are territorial and live in large separated areas in the wild.

About 75 percent of these are gastropods (snails) which feed on microscopic plants the remainder being bivalves. They are also able to absorb oxygen from the lining of their mouth and throat allowing them to stay out of water for long periods of time. brackish water plants .
