They are semi-terrestrial and crawl on muddy areas for long periods, breathing through the skin. They also keep a pouch of water in their gills. Their pectoral fins have been modified into fleshy appendages which are used as legs. They are common in mangroves and on the walls of monsoon drains, tree trunks and breakwaters. They feed on small animals including crabs. They are edible. (Length up to 15cm).
